Frequently Asked Questions
What is a JWT?↓
JWT (JSON Web Token) is a compact, URL-safe token format used for authentication and information exchange. It consists of three parts: Header, Payload, and Signature.
Can JWT be decoded by anyone?↓
Yes. The header and payload of a JWT are simply Base64-encoded, so anyone can read them. The signature ensures the token has not been tampered with, but does not encrypt the content.
