Relax policy requirements on iOS to deviceOwnerAuthentication #36
Description
Summary
The isAvailable method in the iOS implementation currently relies on biometricType being distinct from none
react-native-passkeys/ios/ReactNativePasskeysModule.swift
Lines 110 to 112 in 16570e8
Which requires a policy of deviceOwnerAuthenticationWithBiometrics
This has come up in #30 (closed by the reporting user) and is tangentially related to #27.
Context
An application I am currently working on would like to support passkeys without requiring faceID/touchID to be set up, falling back to passcodes.
Proposal
Because I understand some applications may want to retain "biometrics" as a hard requirement, and in order to avoid a breaking change, I would like to propose this policy level is made configurable.
@peterferguson, given also your position on #27 (which I agree with), would you be open to a PR making this requirement configurable, so some applications can opt for the more lenient policy of deviceOwnerAuthentication over deviceOwnerAuthenticationWithBiometrics?
