Certificate or token QR Code
An x.509 certificate or a JWT bearer token. You can scan and verify one, but you won't find it in our generator.
What is a Certificate or token QR code?
A code carrying an x.509 certificate or a JWT bearer token holds either a public identity credential or, in the case of a JWT, an active authentication token.
Who issues it
A certificate authority issues x.509 certificates. An authentication server issues JWTs, typically for a specific signed-in session or service.
The standard behind it
X.509 defines the certificate format; JWTs follow RFC 7519. Both can carry live credential material.
Why you can't generate this here
The code contains live secret material (2FA seeds, a vault export, a private key or bearer token). Generating one would mint or leak a real secret, so we refuse by design.
You can still scan and verify one with our free QR checker.
Frequently asked
Can I make a Certificate or token QR code with a generator?
No. Certificates need to trace back to a real certificate authority to mean anything, and a JWT is often a live, currently valid session token, generating one would either be meaningless or a real security risk.
Can I check whether one I received is genuine?
Certificates can be checked against the issuing certificate authority's chain of trust. check.qr.abundera.ai will show you the raw structure, but validating a JWT's signature needs the issuing server's key.
