Frequently Asked Questions
What is a JWT?
JWT is a compact, URL-safe token for securely transmitting information. It has three parts: Header, Payload, and Signature.
Does this tool verify signatures?
No, this tool only decodes JWTs. Signature verification requires the secret or public key used to sign the token.
Is it safe to paste my JWT here?
Yes, everything runs in your browser. No data is sent to any server.
What does the exp claim mean?
The exp claim is the expiration time as a Unix timestamp. After this time, the token should not be accepted.
