Implement Sign-up and Login Functionality

[Hashan-Samarakkody]

Description:

Create secure and user-friendly sign-up and login pages for our Inventory Management System.

Requirements:

1. User Interface:    - Design consistent sign-up and login pages    - Use the project's established color theme and font    - Incorporate appropriate, high-quality images    - Ensure responsive design for various devices

2. Sign-up Page:    - Fields: Username, Email, Password, Confirm Password    - Implement client-side validation for all fields    - Server-side validation to double-check all user inputs    - Check database for existing usernames/emails    - Display clear error message if username/email already exists    - Encrypt passwords before storing in the database

3. Login Page:    - Fields: Username/Email, Password    - Implement client-side validation    - Server-side authentication against database records    - Display clear error message for incorrect username/password    - Use secure session management for logged-in users

4. Functionality:    - After successful login, redirect user to Home page    - Implement logout functionality    - Consider implementing "Remember Me" feature

5. Security Measures:    - Use prepared statements to prevent SQL injection    - Implement CSRF protection    - Rate limiting to prevent brute-force attacks    - Secure password reset functionality (if time allows)

6. Testing:    - Test all validation scenarios    - Ensure proper error handling and user feedback    - Verify database operations (user creation, login checks)    - Test on multiple browsers and devices   

7. Access Control:    - Implement a system-wide check to prevent unauthorized access    - Redirect unauthenticated users to the login page when they try to access any protected page    - Use PHP sessions to maintain user authentication state    - Implement middleware or a similar mechanism to check user authentication on every protected route

8. User Flow:    - When an unauthenticated user tries to access any page (except login and signup), redirect to login page    - After login/signup, redirect user to their originally requested page (if applicable)    - Provide clear navigation options for new users to sign up from the login page and vice versa

Acceptance Criteria:

• Users can successfully create new accounts
• Existing users can log in securely
• All user inputs are properly validated
• Passwords are securely hashed in the database
• UI is consistent with project theme and responsive
• Proper error messages are displayed for all error scenarios
• Successful login redirects to Home page
• Unauthenticated users cannot access any part of the application beyond login and signup pages
• All protected routes consistently check for user authentication
• Clear user flow between login, signup, and protected pages

Additional Notes:

• Coordinate with the UI/UX team for design consistency
• Consult with security team member for best practices in authentication
• Document the authentication process for the project documentation
• Ensure the authentication check is applied consistently across all protected pages
• Consider implementing a remember-me functionality for improved user experience
• Document the authentication flow and access control mechanism in the project documentation
