Enhance Login System Functionality

[FOSSit]

Description

This issue aims to elevate the current login system beyond its purely visual state. Our objective is to implement functionalities for storing user credentials, verifying login attempts, and restricting access to protected pages for non-logged-in users.

Focus Areas

• Data Storage: Establish a mechanism to securely store user credentials upon successful registration. You can store the user data inside a sqlite database.
• Login Verification: Implement logic to verify user-provided credentials against the stored data during login attempts.
• Protected Pages: Designate specific pages that require users to be logged in for access.

Checklist

• Implement data storage for user credentials (sqlite database).
• Develop logic for verifying login attempts.
• Establish protected pages with access control based on login status.
• Provide appropriate feedback messages during login attempts.

Contributor Notes

• Feel free to leverage localStorage for this phase.
