What is Token-Based Authentication?
Token-based authentication is a security mechanism where a user authenticates once and receives a token, which is then used to access protected resources without needing to re-enter credentials. The token is typically a digitally signed string and is often JSON web tokens (JWTs) containing user information, expiration time, and authorization details. It offers credential-free access.
Different Strategies to Implement Token-Based Authentication
JWT (JSON Web Token) Authentication
OAuth 2.0 Authentication
OpenID Connect (OIDC) Authentication
