How can I handle user authentication and authorization in SQL Server for a blog?

Implement a user authentication system in SQL Server. Store user credentials (username, password) securely in the database. Use stored procedures or user-defined functions to handle login requests. Implement role-based access control (RBAC) to restrict users' access to specific features or data. You can use SQL Server's built-in security features or third-party authentication providers like Windows Authentication or Active Directory.
