Thieves would allegedly witness customers manually enter their passcodes earlier than bodily stealing the machine and utilizing the passcode to alter Apple ID credentials and entry passwords saved to the Keychain password supervisor.

In consequence, the function requires Face ID or Contact ID authentication (with no passcode fallback) earlier than customers can change necessary safety settings like Apple ID passwords or machine passcodes.
