Feat:[Backend] Login & Signup.

[abhiperfect]

Is your feature request related to a problem? Please describe.
I am facing difficulties with the current authentication system, as it lacks proper login and signup functionality.

Describe the solution you'd like
I would like to implement a robust login and signup system in the backend to improve user authentication and security.

Describe alternatives you've considered
One alternative solution could be to patch the existing authentication system, but I believe building a dedicated login and signup feature would provide a more reliable and scalable solution.

Additional context
