About JWT
JSON Web Token (JWT) is an open standard (RFC 7519) for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is digitally signed.
A JWT consists of three parts separated by dots (.): Header.Payload.Signature
- Header: Contains the token type and the algorithm used
- Payload: Contains claims - information about the user and additional data
- Signature: Used to verify that the message hasn't been changed along the way
