Handling biometric authentication with remote verification

SDK Version:35


I was searching through expo documentation to find a secure storage option that needs biometric authentication to be performed before accessing stored values (like react-native-keychain ). I couldn’t find anything like that. There is no mention in docs that secure store needs fingerprint authentication for access.
Now my only option with expo is to use local authentication and secure store together.
But I’m not sure whether this is the right approach or not. My approach is given below.

  1. store token in secure store during the biometry enrollment phase.
  2. use local authentication to validate the user.
  3. read the token from secure store.
  4. send it to server for verification.

any advice would be appreciated.
