JWT Decoder

Tips

• • A JWT has three parts: Header (algorithm), Payload (claims), and Signature
• • The "exp" claim shows when the token expires; check if your token is still valid
• • Common claims: iss (issuer), sub (subject/user), aud (audience), iat (issued at)
• • Never share JWTs in public as they may contain sensitive user data
• • JWTs are only encoded (not encrypted), so anyone can read the payload
