> To further discourage brute-force passcode attacks, there are escalating time delays after the entry of an invalid passcode at the Lock screen. ...On devices with Secure Enclave, the delays are enforced by the Secure Enclave coprocessor. If the device is restarted during a timed delay, the delay is still enforced, with the timer starting over for the current period.
