Information

The more attempts an adversary has to guess a password, the more likely the adversary will enter the correct password and gain access to resources on the device. Setting a limit on the number of attempts mitigates this risk. Setting the limit at 10 or less gives authorized users the ability to make a few mistakes when entering the password but still provides adequate protection against dictionary or brute force attacks on the password.

2. Tap 'Face ID & Passcode'.
3. When prompted, enter Passcode.
4. Scroll down and turn on 'Erase Data'.
Note: The number of failed attempts is automatically set to '10'.

For Device Enrollment, install a configuration profile to allow only '10' or fewer consecutive failed authentication attempts.
