About JWT
What Is a JSON Web Token?
A JSON Web Token, commonly called JWT, is a compact token format often used to securely transfer information between different systems.
A typical JWT contains three sections separated by periods: the header, payload, and signature.
The header and payload can be decoded and inspected, while the signature is used to verify that the token has not been modified. Decoding a JWT does not automatically verify its authenticity.
