Current problem
The application currently does not offer any App Lock mechanism to prevent unauthorized access.
Proposed change
Implement an App Lock feature on both Android and iOS. When enabled, users can choose one authentication method by default:
- Biometric authentication with a fingerprint
- A personal PIN code
Platform
Android, iOS
Additional information
Use each platform's native security mechanisms to ensure reliable authentication.
If biometric or PIN authentication fails or the App Lock feature encounters an error, fall back to the fluxer user's account password authentification.
App Lock should remain an additional layer of security, separate from the account authentication system.
