Question: Differences between `canImplyAuthentication` and `isPasscodeAuthAvailable` / `getSupportedBiometryType`

[mmiller42]

I have a question about the methods exposed by react-native-keychain.

• canImplyAuthentication() is an iOS-only method and can be passed an optional options argument: { authenticationType: AUTHENTICATION_TYPE.BIOMETRICS | AUTHENTICATION_TYPE.DEVICE_PASSCODE_OR_BIOMETRICS }
• isPasscodeAuthAvailable() and getSupportedBiometryType() are cross-platform methods

My question is: does canImplyAuthentication() actually provide any information that cannot also be determined with isPasscodeAuthAvailable() and getSupportedBiometryType()? If so, what is the precise meaning of "can imply authentication" on iOS?
