FAQ

What is JWT?

JWT (JSON Web Token) is an open standard for securely transmitting information between parties as a JSON object. Commonly used for authentication and information exchange.

What are the parts of JWT?

JWT consists of three parts: Header (contains algorithm info), Payload (contains claim data), and Signature (used for verification).

Is JWT secure?

JWT itself is just an encoding format, not encryption. Sensitive information should not be placed in Payload. Security depends on signing algorithm and key management.
