Tap the Settings icon on your Android device and tap Lock screen and security. Scroll down and tap Screen lock type. Add your fingerprint — follow the instructions on your screen and go through the wizard.
However, biometrics are now being used in web apps to make the authentication process more seamless and safe. Web applications function as standalone software that may be accessed via a browser without installing it on a device. So biometric authentication can only work through the browser.
Progressive web apps do not work with proximity sensors, advanced camera controls, audio or video recording, fingerprint scanning, NFC, or even Bluetooth. Ask your development team for the PWA checklist of features that they will not be able to implement.
It is now possible to use fingerprint authentication but also other strong authentication methods on Chrome.
The Web Authentication API is introduced and explained in the article below which also contains a video from the Google I/O'18 session that presents and demos its features.

It is now possible to use the Web Authentication API in all major browsers, including iOS.
This is a very important development for PWAs.
