New Secret Code Management

Context

To ensure consistency across applications, a revision of the secret code management generated at first login is necessary.

Technical Solutions

1. Implementation of capacitor-biometric-auth plugin for mobile mode
2. Implementation of a 4-digit PIN code for mobile mode
3. Implementation of password authentication for desktop mode

Detailed Process

First Login

Mobile Mode with Biometrics

1. Enter a code
2. Propose biometric authentication usage
3. Save the entered code

Mobile Mode without Biometrics

• Enter a 4-digit PIN code

Desktop Mode

• Enter a password

Subsequent Logins

Mobile Mode with Biometrics

1. Use biometric authentication
2. In case of repeated failures:
   • Reset stored code
   • Request PIN code

Mobile Mode without Biometrics

• Enter PIN code

Desktop Mode

• Enter password

Changes Summary

Mode	First Login	Subsequent Logins
Mobile (with biometrics)	Code + Biometric option	Biometrics (with PIN fallback)
Mobile (without biometrics)	4-digit PIN code	4-digit PIN code
Desktop	Password	Password

Implementation Notes

Mobile Implementation

• Biometric Authentication:

  • Uses capacitor-biometric-auth plugin
  • Requires fallback mechanism to PIN
  • Maximum attempt limit

• PIN Code Requirements:

  • Must be exactly 4 digits
  • Needs secure storage implementation

Desktop Implementation

• Password Requirements:
  • Standard password security rules
