Open the Mifiel app on your smartphone.
If you haven't already, set up your FIEL in the app.
Tap the menu in the top left corner.
Select "Biometric authentication".
Tap "Active".
Enter your e.firma (FIEL) password and tap "Active biometric authentication."
Place your finger on your phone's fingerprint sensor (or look straight at the screen if you have an iPhone with Face ID).
You're all set! You can now sign documents in the app without entering your e.firma password. You can tap "Go back" to return.

How do I link my fingerprint or Face ID to the Mifiel app?

You can link your biometrics to the Mifiel mobile app and use them instead of your password to sign documents.
