TOTP Authenticator Functionality

[wowlikon]

Feature Request:
I would like to request the addition of a TOTP (Time-based One-Time Password) authenticator functionality to Bruce. This feature allows you to use your device as a 2FA key.

Use Case:
Users could generate TOTP codes on their devices, which would then be used for secure authentication processes. This would be particularly useful in scenarios where an extra layer of security is required, such as accessing sensitive data or performing critical operations.

Implementation Details:

1. TOTP Generation: Implement a mechanism to generate TOTP odes based on a shared secret key and the current time.
2. TOTP Verification: Implement a mechanism to verify TOTP codes entered by the user.
3. User Interface: Provide a user-friendly interface for generating and verifying TOTP codes.
4. Configuration: Allow users to configure the TOTP settings, such as the time step and the length of the TOTP code.

Thank you for considering this feature request.
