Local Authentication (Biometrics) can be easily bypassed.
Apple devices have the ability to perform authentication via biometrics, and explains how this works in code in the referenced article. What's important to understand here is that this is basically a way for an iOS application to ask iOS to check whether the user is authenticated to perform the aforementioned action.
During local authentication, an app authenticates the user against credentials stored locally on the device. In other words, the user "unlocks" the app or some inner layer of functionality by providing a valid PIN, password or biometric characteristics such as face or fingerprint, which is verified by referencing local data. Generally, this is done so that users can more conveniently resume an existing session with a remote service or as a means of step-up authentication to protect some critical function.
