How does Face ID work together with an additional PIN?
PrivateProScanner can place an additional PIN step before iPhone system authentication.
This creates another access checkpoint before the app opens.
The user first enters a four-digit PIN and then completes Face ID, Touch ID, or another system authentication method available on the device.
That can be useful for people who want more than the standard biometric gate alone.
The additional PIN is a separate user-controlled layer in front of system authentication.
From the user’s perspective, the flow remains simple: PIN first, then the normal iPhone verification step.
You do not need to understand how the mechanism is implemented internally in order to use it.
PrivateProScanner lets you choose whether system authentication is enough for your needs or whether you want to place an extra PIN in front of it.
