## Features



- **User Authentication**: Register, log in, and reset passwords.

- **CSV-Based Storage**: User data is stored and retrieved from a CSV file.

- **Secure**: Passwords are hashed before being stored.

- **CLI Interface**: Clear menu-driven CLI interface to interact with the system.

- **Logout Feature**: Allow logged-in users to securely log out of the system.

- **Password Strength Checker**: Enforce users to choose strong passwords during registration or reset.

- **Forgot Password Mechanism**: Offer a mechanism for users to recover their password if forgotten.

- **Delete Account Option**: Allow users to delete their account and all associated data.

- **Lockout Mechanism**: Deter brute-force attempts by locking out after consecutive incorrect password attempts.

- **Session Management**: A timeout mechanism that logs out the user after a certain period of inactivity.

- **Audit Log**: Maintain a log of all authentication activities for monitoring and security purposes.

- **Multi-Factor Authentication**: Introduce an option for users to enable additional security layers for logging in.

- **Multi Factor Auth. Add-On**: Give users an option to enable/disable MFA during registration/post-login.

- **Last Login Information**: Display the date and time of the last successful login upon each login.

## Future Improvements



- **Integration with CAPTCHA**: To prevent bots from abusing the registration or login processes, integrate CAPTCHA challenges.

- **API Integration**: Code refactor & allow integration with other systems - used as a service by other apps. For users who may interact with other softwares, provide API key generation & management within the user account.

- **Transition to a Relational Database**: Migrate from a CSV-based system to a more robust relational database like PostgreSQL or MySQL for better scalability, performance, and security.

- **Database Backup and Recovery**: Design a backup mechanism & implement routine backups of the database to safeguard user data and ensure recovery options in case of unexpected system failures.

- **Data Validation and Sanitization**: Enhance the system to validate and sanitize inputs more thoroughly to protect against SQL injection and other potential threats, especially if moving to a more complex database system.

- **OAuth & Social Media Logins**: Allow users to log in using their social media accounts or through OAuth providers like Google, Facebook, etc.

- **User Profiles**: Expand the system to allow users to have profiles where they can update their personal information, profile pictures, etc.

- **User Role & Permissions**: Introduce user roles (Admin, User, Guest, etc.) and permissions, allowing for different levels of access based on the role assigned to a user.

- **Scalability & Concurrency**: Design the system for high availability and ensure that it can handle a large number of simultaneous concurrent users.

- **Rate Limiting**: Introduce rate limiting to prevent abuse from a single IP or user, especially during login or registration processes.

- **Geofencing**: Allow or disallow authentication based on geographic location.

- **Email Integration**: Send email notifications for important activities like password reset, account deletion, or suspicious activity alerts. This can also include a verification email upon registration.

- **Inactive Account Pruning**: Automatically disable or delete accounts that have been inactive for a long period, with prior notification to the user.

- **Advanced Security Features**: Introduce more advanced security features such as device fingerprinting, and machine learning-driven anomaly detection for suspicious activities.

- **Access Review**: Periodic prompts for users to review and confirm their security settings, active sessions, and connected devices.

- **Logging & Monitoring**: Implement a more comprehensive logging and monitoring solution. Integrate with platforms like ELK stack (Elasticsearch, Logstash, and Kibana) or Graylog to monitor and analyze system logs in real-time.
