What is JWT?
JSON Web Token (JWT) is an open standard (RFC 7519) for securely transmitting information between parties as a JSON object. JWTs are commonly used for authentication and information exchange.
A JWT consists of three parts separated by dots:
Header: Token type and algorithm
Payload: Claims and user data
Signature: Verification signature
Common Use Cases
Authentication: Verify user identity after login
Authorization: Control access to protected resources
Information Exchange: Securely transmit data between services
