Kompatibilitetsforklaring
Dette stregkodeformat renderes monokromt med kun forgrunds- og baggrundsfarver. Skabeloner, prik-/øjeformer, gradienter, rammer og centrale logoer gælder kun QR-koder og er skjult her.

Gengives bag QR-koden med reduceret uigennemsigtighed. Tvinger automatisk EC=H, så QR-koden stadig kan scannes gennem fotoet.
Batchgenerering
Upload en CSV for at generere op til 500 QR-koder i en enkelt batch. Hver række bliver sin egen QR — vælg en skabelon eller tilsidesæt 21 egenskaber pr. række: farver, rammer, punkt/øje/øjeæble-stilarter, gradienter, gennemsigtighed, størrelse, fejlkorrektion, format, indbygget logo og mere.
21 kolonner: type, data, filename, frametext, frame, template, fgcolor, bgcolor, size, ec, dotstyle, eyestyle, format, logo, gradient, g2, gtype, gangle, transparent, eyeball, eyecolor. Kun type og data er påkrævet. Brug | til at adskille felter inde i data (f.eks. ssid|password|WPA).
Alle 20 QR-typer understøttes, inklusive URL, WiFi, vCard, MeCard, E-mail, SMS, Begivenhed, Lokation, UPI, SEPA, PayPal, Krypto, Micro QR og rMQR. Download eksempel-CSV'en for at se hver kolonne, alle 40 skabeloner, 11 rammestilarter og de 12 indbyggede logoer i aktion.
1. Download eksempel-CSV'en · 2. Redigér den med dine data · 3. Upload den her
Gem hele QR-koden — type, alle feltværdier, stil, ramme, logo, visitkortdesign — som en enkelt .qr.json-fil. Indlæs den senere for at genskabe alt med ét klik.

How TOTP QR Codes Work
TOTP (Time-based One-Time Password) is the open standard behind every modern authenticator app — Google Authenticator, Authy, 1Password, Bitwarden, Microsoft Authenticator, Aegis, FreeOTP, Raivo, and dozens more. When you set up 2FA on a service, the service generates a shared Base32 secret and packages it into an otpauth://totp/... URI. Your authenticator app scans the QR, stores the secret locally, and starts producing 6-digit codes that change every 30 seconds.
This generator builds the URI for you. Useful for self-hosted services that don't ship a QR generator, password manager migration, lab/test environments, and the moment you need to switch authenticator apps without losing your existing seeds.
Fields explained
- Issuer — the service name (e.g. GitHub). Shown as the heading in the authenticator app.
- Account — usually your username or email. Shown as the subheading.
- Secret — the Base32-encoded shared secret. Standard length is 16, 26, or 32 characters.
- Algorithm — SHA1 (default, supported everywhere), SHA256, or SHA512.
- Digits — 6 (default) or 8.
- Period — 30 seconds (default) or 60.
Privacy
The shared secret is the most sensitive thing you'll ever paste into a QR generator. Abundera QR runs entirely in your browser — the secret never touches a server, never gets logged, never leaves your device. If you're security-conscious, generate codes on an offline laptop and you're golden.
Tilgængelig på 26 sprog
Fuldt oversat UI, native skriftrendering og højre-til-venstre-understøttelse til arabisk og urdu.
Frequently Asked Questions
Which authenticator apps work with these QR codes?
Every standards-compliant TOTP app: Google Authenticator, Microsoft Authenticator, Authy, 1Password, Bitwarden, LastPass Authenticator, Aegis, Raivo, FreeOTP, FreeOTP+, 2FAS, Ente Auth, Yubico Authenticator, KeePassXC, and many more.
Is the secret transmitted to your servers?
No. Abundera QR is a client-side static site. The Base32 secret you paste is encoded into the URI inside your browser and rendered to the canvas locally. We have no servers, no logs, no telemetry — there is nowhere for the secret to go.
What's the difference between SHA1, SHA256, and SHA512?
SHA1 is the default and is supported by every TOTP app on the market. SHA256 and SHA512 are more secure but adoption is uneven — Google Authenticator silently treats them as SHA1, which produces wrong codes. Pick SHA1 unless you control both sides.
Can I use this for HOTP (counter-based) codes too?
Yes — we ship a dedicated HOTP generator alongside this one. Use HOTP for hardware tokens (YubiKey OTP slot) or systems without reliable clocks. The URI scheme is the same; the counter parameter replaces the time period.
How do I get the Base32 secret from my service?
When the service displays its setup QR code, there's almost always a 'Can't scan? Enter manually' link. The text shown there is the Base32 secret. Copy it into Abundera QR to regenerate the QR for a different app.
Can I store multiple TOTP entries in one QR?
No — each otpauth:// URI is a single account. To migrate many accounts at once, use Google Authenticator's export/migration QR feature, which uses a different URI scheme (otpauth-migration://).
Does the QR work if I scan it twice from different apps?
Yes. The QR contains the seed, not a token. Scanning the same QR into two apps gives you two synchronized authenticators. Useful for backup.
