# Application for CBS Authentication with Two-Factor Authentication (2FA)

## Project Overview

The application will provide secure authentication for the CBS (Core Banking System) using Two-Factor Authentication (2FA). It will enhance user security through device binding, biometric login, and secure management of authentication keys.

## Key Functionalities

1. **Device Binding**
The application will allow users to bind their registered device to their account, establishing a trusted device for secure authentication and future login attempts.

2. **Biometric Authentication**
Users will be able to log in using biometric authentication, such as fingerprint or facial recognition, supported by their device. This will provide a convenient and secure alternative to entering credentials repeatedly.

3. **Add Key**
Users will be able to add an authentication key received through a message (SMS or another configured messaging channel). The application will validate the key and associate it with the user's account for authentication purposes.

4. **Forget Key**
Users will have the option to forget a previously registered authentication key. This will remove the key from the user's active authentication configuration, subject to the applicable security and verification process.

5. **Delete Key**
The application will allow users to delete an existing authentication key when it is no longer required or needs to be revoked. Appropriate authorization and confirmation will be required to prevent unauthorized changes.

## Security and Expected Outcome

The application will integrate with the CBS authentication process to provide an additional layer of security for user access. It will ensure secure device registration, convenient biometric authentication, and controlled management of authentication keys.

The overall objective is to improve the security, usability, and reliability of the CBS login process while reducing the risk of unauthorized access through a structured two-factor authentication mechanism.
