Currently, the authentication system in the project uses a custom or alternative method. To improve scalability, security, and ease of integration, migrate the authentication system to use Firebase Authentication.

Tasks:

• Analyze the existing authentication logic and identify all relevant modules/components.
• Integrate Firebase Authentication into the project, supporting email/password and social login providers as needed.
• Update user registration, sign-in, and password reset flows to use Firebase.
• Update documentation to reflect the new authentication flow.
• Ensure all existing features depending on authentication are compatible with Firebase.
• Conduct thorough testing and QA to ensure security and reliability.

Acceptance Criteria:

• All authentication is handled through Firebase.
• Documentation is updated.
• No regressions in user experience or security.

This migration will make the authentication system more robust, secure, and easier to maintain.
