- Clerk JWT templates mint separate tokens for third-party services with claims and lifetime you choose finding
- Clerk session tokens are short-lived JWTs of about one minute that the client refreshes silently finding
- Auth0 applications default to RS256, while legacy HS256 apps sign tokens with the client secret finding
- Auth0 silently drops custom token claims whose names are not namespaced with an http URL finding
- HMAC-signed JWTs need a key at least as long as the hash output, so HS256 requires 256 bits finding
- A JWT cannot be revoked before its exp, so logout needs short lifetimes or server-side state finding
- RFC 8725 recommends an explicit typ header so tokens cannot be replayed across services finding
- Calling jwt.decode in node-jsonwebtoken skips signature verification completely finding
- The JWT kid header is an untrusted hint that must only index a fixed key set, never fetch a key finding
- The JWT aud claim is a string or an array, so a plain equality check fails on multi-audience tokens finding
- JWT verification fails on freshly issued tokens when clock skew exceeds the verifier tolerance finding
- JWT exp, nbf and iat are seconds since the epoch, so JavaScript must divide Date.now by 1000 finding
- A JWT with alg set to none and an empty signature must be rejected by every verifier finding
- JWT algorithm confusion happens when a verifier trusts the token header alg instead of a pinned list finding
- The OIDC at_hash claim covers only the left half of the hash of the access token, not the full digest finding
- Cache an OIDC JWKS by kid and refetch on an unknown kid with a cooldown to avoid a fetch storm finding
- Validating an OIDC id_token means checking iss, aud, azp, exp and nonce, not just the signature finding
