Validate your JWT

Before you register your application, check if your JWT is valid.

You can validate your JWT at jwt.io:

  1. Paste the contents of your JWT into the Encoded Token field.
  2. In the JWT Signature Verification section, paste the full contents of your public key or certificate file into the Public Key field.
  3. Check that the JWT is decoded correctly and the signature matches your public key.

This only checks if the JWT is well-formed, if the header and payload have been correctly signed, and if the signature matches the provided certificate.
