How to use it

To get started with the JWT Decoder, simply select a JWT token, then click 'Decode' to view its header, payload, and expiry details. You can also add a custom HMAC secret to verify the signature of the token.

1. Paste any JWT to decode it
2. Read the header and payload
3. Check expiry and timing claims
4. Verify the HMAC signature

Two practical tips for using the JWT Decoder effectively: first, use it in combination with your favorite IDE or code editor to streamline your development workflow; second, take advantage of our suite's focus on local-first functionality to work offline and avoid relying on external services.
