did_change_authlocal

This is a plugin that allows data to be retrieved and compared when the user has a change in biometric data

The First

The reason I start working on this plugin is because I want to protect users when using biometric authentication (Face ID and Touch ID) when a new layer of protection is needed, which is Passcode. Imagine someone can secretly take advantage by adding their face or fingerprints to the system while your device is unlocked so they can unlock it when you’re not there without your permission, and therefore they’re able to access everything. This plugin prevents just that. Only faces and fingerprints that were added before the first authentication can be used to unlock the app.
