API JWT Best Practices

Use JWTs safely

JWT best practices include using strong algorithms and keys, short expirations with refresh flows, validating issuer/audience, keeping claims minimal/non-sensitive, and rotating keys with clear invalidation paths.

Sign and Validate

Use strong alg/keys; validate issuer, audience, expiry, and signature.

Limit Exposure

Short lifetimes; minimal non-sensitive claims; HTTPS only.

Rotate and Revoke

Rotate keys; support refresh; handle logout/compromise via short TTLs and allowlists.
