Frequently Asked Questions
Does this tool verify JWT signatures?
No, this tool only decodes the token. Signature verification requires the secret key and should be done on the backend.
Is my token safe?
Yes! This tool runs entirely in your browser. Your JWT is never sent to any server. However, be careful with sensitive tokens.
