It doesn’t take much effort to add biometric or PIN authentication to an application. Just configure it! We support 3 layers:

• Application security
• Screen security
• Button security

To configure application security, simply enable biometric authentication in mobile.xml:

<FlutterMobile>
  <parameters>
    <!-- Biometric login -->
    <Mobile.login.biometric>true</Mobile.login.biometric>
  </parameters>
</FlutterMobile>

This option will show biometric or PIN authentication (depends on your device configuration) immediately after first successful manual login:

You will need to re‑authenticate after a longer period of inactivity or if you resume the app after a pause. The biometric authentication is active as long as you don't do a manual logout.

If it's good enough to secure your application on screen level, just add the style:

f_secure

to your screen(s) and you'll see a skeleton:

until successful authentication.

The last option is a security mechanism for single button clicks:
