Get Pixel 4 Face Unlock for Any App with FingerFace

When Apple introduced FaceID, they removed TouchID. Most Android manufacturers still use the fingerprint sensor despite unlocking the face. Even manufacturers such as Oppo or Huawei who replicated Apple's secure face unlocking system offered fingerprint scanners on these devices. However, Google Pixel 4 abandons the fingerprint reader in favor of unlocking the face. However, there are no applications that recognize unlocking faces as a biometric unlocking method. But a new Xposed module called FingerFace can allow you to use Pixel 4 Face Unlock with any application.

While some Android OEMs had already implemented secure face unlocking before Google, they were linked because they did not make Android. Now that Google has implemented secure face unlocking, this is the first time that the Android BiometricPrompt API recognizes a face unlocking system. For those who do not know, the FingerprintManager API is deprecated in favor of the BiometricPrompt API because Android devices nowadays support the unlocking of faces and fingerprints. On Pixel 4, the BiometricPrompt is required to activate the unlocking of the face.

Since this is a new API, most Android apps do not yet support it and use the outdated FingerprintManager API instead. This includes applications such as banking applications, application lockers, password managers, and so on. If Google has made it mandatory for apps to support their implementation of unlocking the face, it will take months before things actually change.
