✨ Dos criadores do Abundera Sign

Free Passkey / FIDO2 QR Code Generator

Two jobs in one form: wrap a FIDO:/ hybrid-transport URI from your WebAuthn server for scan-to-sign-in, or link to your passkey enrollment / management page. No passkeys created here — we only encode what your relying party issues.

    Host your PDF anywhere — Google Drive (use the "anyone with link" share URL), Dropbox, your own server, S3, etc. Paste the public link here. We encode the URL so the QR works forever and never depends on us. Tip: for Google Drive, replace /view in the share URL with /preview for a cleaner mobile view.

    Qualquer arquivo para download — instalador, arquivo compactado, documento, conjunto de dados. Hospede em qualquer lugar; codificamos a URL. O navegador do usuário gerencia o download conforme suas próprias regras MIME.

    JPEG, PNG, WebP, GIF ou HEIC — hospede em qualquer lugar. Navegadores móveis abrem a imagem em tela cheia; navegadores de desktop exibem em linha.

    URLs do YouTube e Vimeo abrem nativamente nos apps em celulares. Arquivos .mp4 / .webm diretos abrem em linha em qualquer navegador moderno.

    MP3 / OGG / WAV / FLAC / M4A direct URLs play inline in mobile browsers. Spotify (open.spotify.com/track/…) and SoundCloud (soundcloud.com/…) URLs open in their apps. Apple Music / Bandcamp / Tidal links also work.

    Restaurant / cafe / bar menu — point to a PDF, an HTML menu page, or your online-ordering platform (Toast / Square / DoorDash / Uber Eats). Print on table tents, host signs, or window stickers. Pro tip: use a frame ("Scan our menu") so customers know what to do.

    Paste your form's share link — either the short forms.gle/… or the long docs.google.com/forms/d/e/…/viewform form. We auto-prefer forms.gle when both are available since the shorter URL produces a denser QR. Works for surveys, registrations, RSVPs, lead capture, classroom polls.

    Cole uma fatura BOLT11 (lnbc...) ou um endereço Lightning. Adicionamos o prefixo do esquema URI lightning: para que qualquer carteira Lightning possa escaneá-lo.

    Use this if you're enrolling a new 2FA account in an authenticator app (Google Authenticator, Authy, 1Password, Bitwarden). Do not screenshot, email, or photograph this QR — the secret inside it is a permanent key to the account.

    Ajustes avançados

    Compatível com Google Authenticator, Authy, 1Password, Bitwarden e qualquer aplicativo TOTP padrão.

    Use this if you're provisioning a counter-based hardware token (YubiKey OTP) or a system without a reliable clock. Do not use when TOTP will do — HOTP counters drift, and recovery is harder after a dropped sync.

    Ajustes avançados

    HOTP (RFC 4226) is the counter-based sibling of TOTP. Use it for hardware tokens like YubiKey OTP or for systems without reliable clocks. Same otpauth:// scheme; counter increments per code instead of advancing on time.

    Use this if you're a carrier or MVNO issuing an eSIM activation profile to a customer (iOS 17.4+ / Android 13+). Do not share this QR after it's been scanned — the SM-DP+ activation is usually single-use and the profile belongs to one device.

    Código de ativação GSMA SGP.22 conforme LPA. iOS 17.4+ e Android 13+ os escaneiam diretamente para provisionar perfis eSIM.

    Per RFC 3261, opens a SIP softphone (Linphone, Zoiper, Bria, etc.) and dials the address. sips: forces TLS for signalling. Works with Asterisk, FreeSWITCH, 3CX, and any standards-compliant PBX.

    Opens the system MMS composer to send a multimedia message (text + image/audio/video attachment). Distinct from sms: in that the recipient receives an MMS-formatted message. iOS, Android and most carrier apps honour this scheme.

    Paste the QR URL from your Alipay Receive Money page (Settings → My QR Code → Save). We pass it through verbatim. The Alipay app, AliPayHK, and any device with the Alipay+ scanner will recognise the URL or QR.

    Personal receive codes start with wxp://f2f. Merchant codes are https://payapp.weixin.qq.com/... URLs from the Weixin Pay merchant portal. Paste either; we encode verbatim. The WeChat app and any Weixin-Pay-enabled scanner will resolve it.

    Swish is Sweden's national P2P / merchant mobile-payment service. Payee can be a private mobile number (Swish-number) or a 1234-style merchant alias. The Swish app on iOS and Android scans the standard swish://payment?data=... URI.

    Vipps is Norway's dominant mobile-payment app (now Vipps MobilePay across the Nordics). Send to phone emits a vipps://send?... deeplink for P2P; Merchant short-link wraps a https://qr.vipps.no/... URL.

    Paste the link from your Mercado Pago Cobrar page (the https://mpago.la/..., https://link.mercadopago.com.br/..., or full mercadopago.com short-link). Works across MP apps in Argentina, Brazil, Mexico, Chile, Colombia, Uruguay and Peru.

    Use this if you need pharma / medical / direct-part-marking symbology or you're encoding for industrial imagers. Do not use for consumer-facing signage — Apple iPhone cameras do not decode Data Matrix natively.

    Data Matrix is a square 2D matrix barcode (ISO/IEC 16022) used in healthcare, electronics, manufacturing, and direct-part marking. Holds up to ~2,335 alphanumeric characters in a single tag. Note: this is not a QR code — QR-only styling (eyes, dots, gradients, frames, logos) is disabled and the basic monochrome render is used.

    Use this if you're generating boarding passes, transit tickets, or electronic-ID payloads for dedicated scanners. Do not use for public marketing print — most phone cameras won't decode Aztec reliably.

    Ajustes avançados

    Aztec Code (ISO/IEC 24778) is the 2D barcode used by airline boarding passes, train tickets, and electronic ID. Designed to scan well on phone screens and at low contrast. Holds up to ~3,067 alphanumeric characters. Not a QR; QR-only styling is disabled.

    Use this if you're printing an IATA-compliant boarding pass (Aztec, QR, or PDF417) for gate scanners at any of the 200+ airlines that implement BCBP / Resolution 792. Do not use this to board a real flight you didn't check in for — the format carries no cryptographic signature; airline gate systems validate against their own DCS, not against the QR itself.

    Advanced — paste raw BCBP string

    If your airline or PSS (Amadeus / Sabre / Navitaire / HP Shares) already exports a full BCBP string, paste it here to preserve conditional fields, multi-leg data, and security sections the structured form doesn't expose.

    IATA Resolution 792 / BCBP Implementation Guide v7. Encode as Aztec for mobile boarding passes, PDF417 for printed Type-A stock, or QR for modern gates. We build the mandatory M1 header + a single leg; paste the full BCBP in Advanced for multi-leg itineraries.

    Use this if you need stacked-linear barcode for driver's-licence parsing, boarding passes, airbills, or AAMVA workflows. Do not use for normal consumer phone-camera signage — coverage is uneven across readers.

    Ajustes avançados

    PDF417 (ISO/IEC 15438) is a stacked linear barcode used on US driver's licences, passports, FedEx airbills, and AAMVA-encoded ID cards. Holds up to ~1,800 ASCII characters. Not a QR; QR-only styling is disabled.

    Use for legitimate purposes only: AAMVA parser testing, kiosk & age-gate development, accessibility tools, and demoing AAMVA workflows. Producing a counterfeit government ID is identity fraud and is prosecuted as a felony in every US state. Use real data only when you own the source license, or use synthetic data clearly marked as such.

    Gera um código de barras PDF417 seguindo o Padrão de Design de Cartão AAMVA. Escaneie de volta com o scanner deste site para ver o parser de Visualização de Licença estruturado em ação.

    Code 128 (ISO/IEC 15417). Comprimento variável, alta densidade, codifica o conjunto ASCII completo. Usado em etiquetas de envio (UPS, FedEx, DHL o usam para rastreamento interno), cadeia de suprimentos e rotulagem industrial.

    Code 39 (ISO/IEC 16388). O código de barras alfanumérico original, compatível com todos os scanners existentes. Usado em pulseiras de pacientes, logística militar do DOD (LOGMARS) e etiquetagem de inventário.

    Code 93 — sucessor mais compacto do Code 39 da Symbol Technologies. Dois caracteres de soma de verificação obrigatórios (C e K) o tornam mais confiável em etiquetas danificadas.

    Codabar (NW-7) — usado por bancos de sangue dos EUA, airbills da FedEx (legado), bibliotecas (EUA/CA/UE) e revelação fotográfica. Autovalidável; não requer dígito de verificação.

    EAN-13 / GTIN-13 — identificador global de produto de varejo. Usado fora da América do Norte (que usa UPC-A) em todos os produtos de consumo. Use o número GS1 de 12 dígitos; o 13.º dígito de verificação é calculado para você.

    EAN-8 / GTIN-8 — identificador compacto para embalagens pequenas onde o EAN-13 não cabe (chicletes, pilhas, etc.).

    UPC-A / GTIN-12 — identificador de produto de varejo norte-americano. Use o número GS1 de 11 dígitos.

    UPC-E — variante compacta de 8 dígitos com supressão de zeros do UPC-A para embalagens pequenas.

    ITF-14 (Interleaved 2 of 5) — padrão GS1 para caixas de envio / embalagens externas. Identifica o produto interno (GTIN-14). Usado por todos os grandes varejistas e armazéns 3PL.

    Número de Identificação do Veículo conforme ISO 3779. Codificado como código de barras Code 39 para compatibilidade com scanners de DMV, registros automotivos e fluxos de seguros/títulos. O 9.º caractere é um dígito de verificação (autovalidado, não autocalculado — VINs inválidos ainda são codificados para testes).

    Paste the link from your Payconiq merchant portal — typically https://payconiq.com/t/1/... for transactions or https://payconiq.com/l/1/... for static merchant QRs. Scanned by Payconiq, Bancontact, KBC Mobile, Belfius, ING, BNP Paribas Fortis, and most Benelux banking apps.

    EPC QR Code (EPC069-12 / Girocode) — the European standard for SEPA Credit Transfer initiation via QR. Supported by most European banking apps including Sparkasse, ING, KBC, BNP Paribas, Rabobank, and all EPC-compliant banks.

    Paste the URL to your .pkpass file or Apple Wallet deep link. Scanning opens the pass directly in Apple Wallet on iOS devices.

    Paste the Google Wallet save link from the Google Pay API or your pass issuer. Scanning opens the pass directly in Google Wallet on Android devices.

    Codifica a linha completa de authorized_keys. Escaneie para copiar e colar a chave em uma nova máquina.

    Para chaves muito longas, use rMQR paisagem ou divida em vários QRs. O QR padrão suporta até ~2 KB.

    Os aplicativos móveis oficiais do WireGuard escaneiam estes diretamente. Nunca inclua sua chave privada em um QR impresso — apenas para compartilhamento digital.

    Use this if your WebAuthn server issued a FIDO:/ URI for cross-device passkey sign-in, or if you want a QR that opens your passkey-management page. Do not use this to "create" a passkey — the URI is issued by your relying party; we only wrap it as a QR.

    The FIDO:/ URI is generated by your relying party (the site you're signing into) and is session-specific — it embeds a short-term session key plus a long-term identity key. Paste it here and we wrap it as a QR. Apple Safari, Chrome, Edge, and 1Password all recognise the FIDO:/ scheme for CTAP 2.2 hybrid transport.

    Use this if your healthcare provider, state health department, or health-wallet app gave you a shc:/ URI (vaccination record, lab result, discharge summary, prescription) and you want to share it as a QR code. Do not use this to "create" a health card — the cryptographic signature is issued by the health authority; we only wrap the URI as a QR.

    The URI starts with shc:/ followed by digits. If your card is chunked (shc:/1/2/..., shc:/2/2/...), paste one chunk at a time and generate one QR per chunk — SHC verifiers scan them in sequence. Single-chunk payloads fit in a V22 QR (~1,191 digits).

    Use this if you're a brand owner preparing for the GS1 Sunrise 2027 cutover or you need a single code that carries product identity + batch/expiry/serial. Do not use as a standalone marketing QR — retailers' POS systems will treat it as inventory data first, URL second.

    O GS1 Digital Link é a alternativa moderna e compatível com a web ao código de barras EAN-13 para produtos de varejo. O domínio do resolvedor é id.gs1.org por padrão, mas você pode usar o seu próprio.

    Use this if you're a manufacturer or importer preparing for the EU Digital Product Passport (DPP) mandate, operational 19 July 2026 under ESPR Regulation (EU) 2024/1781. Each individual product instance sold in the EU needs a scannable QR or Data Matrix resolving to its DPP record. Do not use this as a marketing QR — the URL should resolve to structured DPP data (JSON-LD), not a landing page.

    Mais campos (opcional)

    The QR encodes a GS1 Digital Link URL pointing to your DPP record — the same URI syntax as GS1 Digital Link (Article 10 mandate explicitly references it). Your resolver must return structured DPP data (GS1 Digital Link resolver or custom JSON-LD endpoint) and the unique identifier must comply with ISO/IEC 15459:2015.

    Cole o link de compartilhamento do aplicativo Spotify ou apenas o ID. Nós construímos a URL open.spotify.com automaticamente.

    O formato depende da plataforma — para Mastodon use @usuário@instância, para Bluesky use handle.bsky.social, para Nostr cole a chave npub.

    The d + numeric ID from your TripAdvisor listing URL. Scanning opens the Write Review page.

    Routes happy customers to your public review page and unhappy ones to a private channel. The branching happens in the user's browser via a hash splash at /review/ — no backend, no tracking. Important: Google's review-gating policies prohibit hiding negative reviews — use this only to collect private feedback in addition to allowing all customers to leave a public review if they choose.

    Tries the deep link first; if the app isn't installed, shows the right store button (App Store on iOS, Play Store on Android). On desktop, opens the web fallback. OS detection happens at /app/ — no backend.

    Paste any meeting invite link. For Zoom, Google Meet, and Teams we extract the canonical join URL automatically.

    If a URL is provided, the QR opens the page with your promo code appended as ?code=YOURCODE. Without a URL, the QR encodes the plain promo code text.

    BLIK — Poland's dominant mobile payment system used by all major Polish banks. The 6-digit code is time-limited and confirms the transaction in the payer's banking app.

    Interac e-Transfer — Canada's national real-time money transfer service, supported by all major Canadian banks and credit unions.

    MB WAY — Portugal's leading mobile payment app linked to SIBS/Multibanco. The phone number identifies the recipient in the MB WAY network.

    Boleto Bancário — Brazil's ubiquitous printed-invoice payment method, accepted by every Brazilian bank. Paste the 44-digit linha digitável (bank slip) or the 48-digit concessionária code. Banking apps recognize the digit pattern and auto-fill the payment.

    QRIS — Bank Indonesia's unified QR (EMVCo MPM, live cross-border to Thailand, Malaysia, Singapore, Vietnam via ASEAN RPC). Accepted by every Indonesian bank and e-wallet (GoPay, OVO, DANA, ShopeePay, LinkAja). The QR encodes the NMID + merchant name + optional fixed amount.

    VietQR — Vietnam's national unified QR built on NAPAS + the ASEAN Regional Payment Connectivity standard. Every Vietnamese retail bank app scans it. Bank BIN examples: 970436 (Vietcombank), 970418 (BIDV), 970422 (MB Bank), 970415 (VietinBank).

    QR Ph — the Philippines' national unified QR standard from Bangko Sentral ng Pilipinas (BSP), sitting above the individual e-wallets (GCash, Maya) and all major retail banks. Interoperable EMVCo-MPM format.

    KHQR — National Bank of Cambodia unified QR. Live cross-border to Thailand (PromptPay), Laos (Lao QR), Vietnam (VietQR). Supports both USD and KHR since Cambodia is dual-currency.

    Lao QR — Bank of the Lao PDR unified QR. Accepted by BCEL, LDB, JDB, and every Lao retail bank app. Cross-border live with Thailand (PromptPay), Cambodia (KHQR), Vietnam (VietQR).

    PayShap — BankservAfrica's real-time rapid payment rail, live across every major South African bank (Absa, FNB, Nedbank, Standard Bank, Capitec, Discovery, Investec, TymeBank). Send in <10 seconds by mobile number or ShapID.

    Use this if you want to share your Zelle-registered email or US phone number as a scannable contact card. Note: Zelle has no universal QR URI scheme — scanners open your chosen contact method; the payer still initiates the transfer from their own banking app. This QR is a convenience, not a direct-pay link.

    Zelle is built into every major US bank app (Chase, Bank of America, Wells Fargo, Capital One, Citi, and ~2,000 others). This QR encodes a mailto: or tel: that opens the recipient's contact card. The payer then opens their banking app, taps Zelle, and pastes the email / phone — the actual transfer happens bank-to-bank, never through us.

    Satispay — Italy's licensed payment-institution mobile wallet. Accepted by 300,000+ Italian merchants. Customers scan the QR from the Satispay app; no card data, no typing PIN.

    Use this if you're piloting Drex (Brazil's wholesale/retail CBDC, launched 2026 by Banco Central do Brasil on a Hyperledger Besu DLT). Drex settles via the existing Pix infrastructure; most merchant integrations accept the same Pix EMVCo-style QR with a Drex flag.

    Drex — Brazil's tokenised central bank digital currency, Phase-1 live 2026. Settles through existing Pix QR infrastructure during the transition. For pure-Pix transfers, use Pix.

    Use this if you're testing Digital Euro pilot rails (ECB preparation phase, 2023–present; live retail issuance decision expected late 2026). Format follows EPC / SCT-Inst QR patterns with a CBDC flag. Not yet a production payment method — pilot participants only.

    Digital Euro — the ECB's proposed retail CBDC. Preparation phase runs through Oct 2026; live issuance pending Governing Council decision. For standard euro bank transfers, use SEPA or EPC Girocode.

    Digital Ruble — Bank of Russia CBDC. Pilot banks began retail rollout September 2026; mandatory distribution via commercial banks scheduled phase-in through 2027. Each wallet address is issued by a participating bank.

    e₹ / Digital Rupee — the RBI's retail CBDC, live via pilot banks since December 2022. QRs share UPI-style VPAs with an @{bank}digital suffix (e.g. @icicidigital, @hdfcdigital). Interoperable with the existing UPI QR landscape since October 2023.

    Use this if you want a reusable Lightning receive QR. BOLT12 offers (lno1...) don't expire and can be scanned repeatedly, unlike BOLT11 invoices. Not all Lightning wallets support BOLT12 yet (Phoenix, Core Lightning, LNDk, Zeus partial); check your wallet before handing out printed QRs.

    BOLT12 "offers" are the reusable successor to BOLT11 Lightning invoices — no per-payment re-issuance, no 1-hour expiry. Generated server-side by Core Lightning (lightning-cli offer), LNDk, or Strike. Our QR is a passthrough.

    Monero (XMR) is the largest privacy-by-default cryptocurrency. QR emits a monero: URI per the community-standard scheme; GUI and CLI wallets, Cake, MyMonero, Feather, and Monerujo all parse it.

    Use this if you're printing the onboarding QR for a Matter-certified smart-home device (light bulb, sensor, lock, thermostat). The code admits the device into any Matter ecosystem — Apple Home, Google Home, SmartThings, Alexa, Home Assistant. Do not share once the device is paired — anyone with the code can commission it into a fresh fabric.

    Matter QR payload (Connectivity Standards Alliance spec). Format is MT: + base38-encoded CBOR. Manual pairing code (11 digits) is the fallback for devices without a QR. Every Matter-certified product is shipped with one from the manufacturer.

    WalletConnect v2 (now called Reown) URI. Generated by the dApp when a user clicks "Connect Wallet". Scanning with MetaMask, Trust, Coinbase Wallet, Phantom, Rainbow, Zerion, and 300+ other wallets completes the pairing. Session-specific — URIs are single-use.

    NFT claim / mint URLs from thirdweb, Reown, Zora, Manifold, or any chain-aware frontend. Scanning opens the claim page in the user's browser; WalletConnect or injected provider handles the on-chain mint. Works across Ethereum, Base, Polygon, Optimism, Arbitrum, Zora, Solana (scheme-dependent).

    Tailscale auth-key URL (ephemeral or reusable) from the admin console. Scanning on a new device triggers the auth flow. Works for Tailscale, Headscale (self-hosted), and compatible forks. Don't publish reusable keys in public QRs — anyone can join your tailnet.

    Works for any ActivityPub-compatible server (Mastodon, Pleroma, GoToSocial, Akkoma). Profile URL for sharing; OAuth authorize link for signing into a third-party app.

    Use this if you're printing a pet tag, key-chain sticker, laptop label, water-bottle decal, or anything else you want returned if lost. Scanner sees an "if found" contact prompt; owner is never exposed until they choose to respond.

    No account, no tracking, no service that can paywall your tag. The QR goes straight to your chosen contact method with a pre-filled "I found this" subject line. Works for pet tags, luggage, bike locks, cameras, anything with a visible printable surface.

    PayID é o serviço de endereçamento de pagamentos instantâneos da Austrália. Funciona com qualquer app bancário australiano habilitado para NPP.

    ZATCA / FATOORA é o formato obrigatório de QR de e-fatura da Arábia Saudita, exigido em cada fatura comercial desde 2021.

    URI BIP-21 unificado combinando um endereço Bitcoin on-chain e uma fatura Lightning. Carteiras modernas escolhem Lightning quando disponível e fazem fallback para on-chain.

    Why Abundera QR

    What is a passkey?

    A passkey is a phishing-resistant replacement for passwords, standardised jointly by the FIDO Alliance and the W3C (WebAuthn Level 3). Instead of a shared secret the user types, the user's device holds a private key and signs a challenge from the website. Apple, Google, and Microsoft all support passkeys natively in iCloud Keychain, Google Password Manager, and Windows Hello respectively; password managers like 1Password, Bitwarden, and Dashlane sync passkeys across devices.

    Why does a passkey sign-in need a QR code?

    When you sign in on a device that doesn't hold your passkey — a friend's laptop, a desktop that's never paired with your phone — WebAuthn uses CTAP 2.2 hybrid transport (historically called "caBLE") to prove possession of the passkey that lives on your phone. The desktop displays a QR encoding a FIDO:/ URI. You scan it with your phone camera, approve the sign-in with Face ID / Touch ID / PIN, and the two devices complete a BLE-bootstrapped encrypted tunnel to finish the WebAuthn ceremony. The desktop is signed in; no password, no typed code, no shared secret.

    What's in the FIDO:/ URI?

    The URI encodes a CBOR structure carrying (a) a short-term symmetric session key unique to this sign-in, (b) a long-term asymmetric identity key the phone uses to re-pair silently in future sessions, and (c) BLE advertisement coordinates the phone will listen on. It is single-use for the initial scan — the tunnel key is ephemeral. The server re-issues a fresh URI for each new hybrid-transport handshake.

    Two jobs this generator covers

    1. Cross-device sign-in (FIDO:/ URI) — paste a URI your WebAuthn server produced and we wrap it as a QR. Useful when your server renders the URI as text (e.g. for a kiosk display, a printed troubleshooting handout, or a custom authenticator UI).
    2. Passkey management page — encode a stable URL like https://account.example.com/security/passkeys. Print on onboarding cards, add to welcome emails, or surface in-app so users can enroll a passkey without typing a URL.

    What this generator is not

    We do not create passkeys. A passkey is a cryptographic keypair that is generated on the user's device during the WebAuthn navigator.credentials.create() flow, bound to a specific relying party, and stored in the OS/password-manager credential store. No QR-code tool can generate a passkey — and anything that claims to is either creating something that isn't a passkey, or is a phishing attempt.

    Compatibility

    The FIDO:/ scheme is supported by: Apple Safari and iCloud Keychain (iOS 16+, macOS Ventura+), Chrome / Chromium-based browsers (desktop and Android), Microsoft Edge, 1Password 8, Bitwarden (browser extension), Dashlane, and Google Password Manager. Keepass variants are still adding support.

    Frequently Asked Questions

    What is a passkey?

    A passkey is a device-held cryptographic credential that replaces a password. Your device holds a private key; the website holds the public key. Sign-in proves possession of the private key via a WebAuthn challenge. Phishing-resistant by design — the signature is bound to the origin so a look-alike site can't collect it.

    Who issues the FIDO:/ URI?

    The relying party (the website you're signing into). Chrome, Safari, and Edge generate one automatically when you click "Sign in with a passkey" on a device that doesn't hold one. Self-hosted WebAuthn servers using libraries like SimpleWebAuthn or WebAuthn4J can produce one programmatically.

    Is the FIDO:/ URI reusable?

    The session tunnel key inside the URI is single-use. The long-term identity key enables the phone to re-pair silently for future sessions — so after the first scan, the user can sign in on that desktop again without re-scanning. But each fresh ceremony on a brand-new device requires a fresh QR.

    Can I print this QR and reuse it?

    No. The URI is session-specific and expires the moment the WebAuthn ceremony times out (usually 60–120 seconds). If you want a QR for printed onboarding material, use the "Passkey management page" mode instead and encode a stable URL.

    Does this QR contain my passkey?

    No. The passkey (private key) stays on the user's phone / authenticator and never leaves it. The FIDO:/ URI carries only session material for the two devices to establish an encrypted tunnel. This is a core design property of WebAuthn: private keys are non-exportable.

    Which browsers and apps scan FIDO:/ URIs?

    Apple Safari (iOS 16+, macOS Ventura+), Chrome / Chromium (all platforms), Microsoft Edge, 1Password 8, Bitwarden browser extension, Dashlane, and Google Password Manager. Most native iOS and Android camera apps also recognise the scheme and hand it off to the system passkey flow.

    What's the difference between a passkey and a U2F security key?

    U2F (FIDO1) keys are second-factor only — they sign a challenge after you enter a password. Passkeys (FIDO2 / WebAuthn) are first-factor and can replace the password entirely. A physical YubiKey can hold either; the difference is how the relying party requests credentials.

    Can I use this for FIDO U2F / security-key enrollment?

    Not directly. FIDO U2F uses a different URL scheme and is typically handled via USB, NFC, or Bluetooth — not a QR. For passkey / FIDO2 cross-device flows, the FIDO:/ hybrid-transport URI is the right primitive.

    Is there a QR format for passkey export / import?

    As of early 2026, there is no standardised QR format for transferring passkeys between credential providers. Industry work is ongoing via FIDO's Credential Exchange Protocol (CXP) — watch this space. In the meantime, passkey sync happens via provider-specific cloud (iCloud Keychain, Google Password Manager, 1Password) not via QR.
