What advantage does using access tokens confer in user session management?

Using access tokens in user session management provides a significant advantage by reducing the need for constant user re-authentication. Access tokens serve as proof of a user's identity and permissions, allowing them to access various resources without having to log in repeatedly. This seamless experience enhances usability and efficiency, particularly in environments where users need to authenticate to multiple services or applications.

Tokens typically have a limited lifespan, meaning that while they reduce the frequency of authentication prompts, they still ensure security by requiring re-authentication after a certain period. This mechanism strikes a balance between user convenience and security, allowing users to engage with applications more fluidly while maintaining safeguard protocols.

In contrast, other options like increasing complexity in user access management or forcing a single authentication method detract from the user experience. Limiting access only to essential applications does not align with the broader usability advantage provided by access tokens, which are designed to facilitate broader access while maintaining security.
