I have built an android app using fingerprint authentication in Android Studio. I need to build the same thing but using React Native for android and iOS. How to go for it?

Have a look at this library.
This library supports face and touch identification on both iOS and Android.
But it clearly said for android its experimental, but I didn't faced any problem for android.
Also it blocks too many requests which is nice feature to have, provides good documentation.

- react-native-touch-id npmjs
