Why is the additional PIN entered twice?
The additional PIN is entered twice to reduce the risk that a simple typo will be treated as an intentional incorrect code.
One mistyped digit should not immediately trigger a strict protective action.
PrivateProScanner therefore asks for the four-digit PIN again.
If the two entries are different, the app treats the situation as a likely input mistake and does not start the emergency cleanup scenario.
If the same incorrect PIN is confirmed twice, the app can treat that as a confirmed wrong-code event rather than a single accidental tap.
This design balances strict protection with protection against ordinary user error.
The goal is to avoid data loss from one accidental typo while still allowing the PIN to serve as a meaningful security control.
PrivateProScanner deliberately separates “I typed something wrong once” from “the same wrong code was confirmed twice.”
