Stateless authentication in Angular refers to an approach where the server doesn’t maintain user session information. Instead, it relies on tokens (e.g., JWT) sent by clients for each request. The token contains necessary data for authentication and authorization.
This method is important due to its scalability, as servers don’t need to store session data, reducing memory usage. It also simplifies load balancing since any server can handle requests without needing shared session storage. Stateless authentication enhances security, as tokens are short-lived and can be revoked easily if compromised.
