- I was thinking of implementing a sign-in with Biometric for a react native app. So when user logs into the app and they go background, maybe visit a different app or maybe locks their phone. and then the user tries to go back to the app foreground, we prompt either a faceID or fingerprint to log in to the app. I have seen this feature being implemented by Fin-tech apps.
- I would like to get help on the best way to implement this feature for a react native app as I couldn’t find any related topic on the internet.
- Just for informational purposes, our app already has biometric authentication implemented which authenticates users when they are performing key features of the app.
- Would the sign-in with biometric feature be implemented with react native AppState API which can tell you if the app is in the foreground or background, and then prompt the user with a biometric security prompt when the user is back in the foreground, or implement the security prompt on splash screen itself?
