FAQ
What is JWT?
JWT (JSON Web Token) is an open standard token format for securely transmitting information between parties, commonly used for authentication.
Is decoding JWT the same as verifying it?
No. Decoding only reads token content without verifying the signature. Verification requires the secret key to check signature validity.
