JWT Token
Frequently Asked Questions
Is it safe to paste my JWT here?
Yes. The token is decoded entirely in your browser. No data is sent to any server. However, never share JWTs from production systems publicly.
Can this tool verify JWT signatures?
This tool decodes and displays the token contents. Signature verification requires the secret key, which is not needed for inspection purposes.
