Store a password behind biometric authentication.
This is a microlibrary for storing a password in the keychain, instructing the keychain to only give it back if the user first authenticates with TouchID or FaceID.
note: Android is currently unsupported, I hope to implement this soon.
note: On iOS, in order for your user not to receive a prompt that your app does not yet support Face ID, you must set a value for the Privacy - Face ID Usage Description (NSFaceIDUsageDescription) key in your app’s Info.plist.
import 'package:flutter_biopass/flutter_biopass.dart' show BioPass; final bioPass = BioPass(); // When the user signs up or logs in for the first time, store the password in the keychain: await bioPass.store('P@ssw0rd'); // When asking the user to log in, first try retreiving the saved password which will, if a password is stored, trigger a biometric authentication prompt: // If `result` is `null`, then either the user cancelled the authenticaiton, or there was no password saved. final result = await bioPass.retreive(withPrompt: 'Example prompt text...'); // When the user manually logs out, delete the stored password from the keychain: await bioPass.delete();
- 🎉 Add initial implementation
Demonstrates how to use the flutter_biopass plugin.
