What steps follow after user authentication by login and password?

After successful user authentication by login and password, the following steps usually follow:

1. Authorization — checking the user's access rights to certain resources or operations.
2. Session creation — generating a unique session identifier that links the user to their state on the server.
3. Token or cookie issuance — to maintain authentication state on the client and for subsequent requests.
4. Security context setup — loading user roles and permissions into the application context.
5. Login event logging — recording login information for audit and monitoring.

Example in Java using session:

HttpSession session = request.getSession();
session.setAttribute("user", authenticatedUser);

Thus, after authentication, access management and user state maintenance in the application are ensured.
