Frequently asked questions
Does decoding a JWT verify its signature?
No, decoding only reveals the header and payload contents. Verifying the signature requires the secret or public key used to sign it.
Is it safe to paste a JWT into a browser tool?
Since decoding happens locally in your browser and the token isn't sent anywhere, it's generally safe, though you should still avoid sharing tokens containing sensitive data with third parties.
