**Issue: Unable to use New Pixel 4 / Face Unlock mechanism to unlock the Monzo app
**Details to reproduce: Enabling the option to ‘unlock app by identity check’ results in a prompt that asks the user to setup fingerprint on their device. User doesn’t physically have a fingerprint reader on their device, but only the new Face Unlock (on the Pixel 4 series devices).
Please note the Face Unlock identity check has been working fine for authenticating payments and I currently have the new Biometrics API option enabled in Monzo Labs.
**OS: Android 10, Feb 2020 Update
**Device: Pixel 4 XL
**App Version: 3.19.0
