auth sessions

Stateful server-side tracking that maps unique session IDs to secure user data stores.

Auth sessions maintain persistent user state by storing a unique identifier in a browser cookie while keeping sensitive data on the server. Unlike stateless JWTs, sessions allow for immediate revocation and precise control over concurrent logins. Using high-speed stores like Redis (sub-millisecond latency) ensures that verifying a user's identity on every request doesn't bottleneck the application. This approach is the industry standard for banking platforms and high-security dashboards where real-time session management is non-negotiable.
