Frequently Asked Questions

What does a JWT decoder show?
It decodes the header (algorithm, type) and payload (claims like sub, exp, iat) from the Base64 parts. It does NOT verify the signature—use your auth library for that.
Is it safe to paste my JWT?
JWTs often contain sensitive data. Use only with test tokens or in private. Never paste production tokens in public tools. Consider local/offline decoders.
Why can't I verify the signature?
Verification needs the secret or public key. Online decoders don't have your keys. Decoding is for inspection only; verification happens in your app.
