The primary objective is to ensure that the authentication system of a portfolio website functions correctly, allowing authorized users to log in while preventing unauthorized access. This involves verifying the login process with valid and invalid credentials, ensuring that error messages are displayed appropriately, and checking for potential security vulnerabilities such as session hijacking or brute-force attacks.

Additionally, the system should provide a smooth user experience by offering clear feedback, proper redirects, and secure session management. Since portfolio websites may include an admin panel or private sections for managing content, maintaining strict authentication controls is essential to prevent unauthorized modifications or data breaches.

 

A well-functioning login system should provide a seamless experience for valid users while maintaining strong security measures against incorrect login attempts. Issues such as unclear error messages, improper redirects, or session handling problems can negatively impact usability and security.

Testing different scenarios, including valid logins, incorrect credentials, and session expirations, helps identify potential weaknesses.

 

To validate authentication, the login process is tested with correct and incorrect credentials. A successful login should redirect the user to the appropriate section, displaying personalized content. Incorrect attempts should trigger clear error messages without exposing sensitive information.

Proper session handling, logout functionality, and security measures such as account lockout after multiple failures are also checked to ensure a robust authentication system.
