### Add Password Authentication & Encryption #### Proposed Solution 1. **Add password authentication** for all user login and registration actions. 2. **Encrypt passwords** before storing them in the csv using a secure algorithm (e.g., **SHA-256**, **bcrypt**, or **argon2**). 3. **Verify passwords** during login by comparing the hashed version of the entered password with the stored hash. 4. (Optional) Implement **password strength validation** and **password reset functionality**. (100-200 extra bounty points) #### Acceptance Criteria - [ ] Users can register with a password that is securely hashed. - [ ] Login authentication validates passwords securely. - [ ] No plain text passwords are stored in the csv file. - [ ] Unit tests verify encryption and authentication functionality
