IPhone 1 1 has a face ID, but for the sake of user safety, you still need to enter a password to unlock it, which will eventually lead to property losses.

Before using Face ID, you need to set another screen lock password on the device. For the security of equipment and personal information, in these special cases, users need to enter a password to complete security verification: the equipment has just been powered on or restarted; The equipment has been locked for more than 48 hours; No password was used to unlock the device in the past six and a half days, and no ID card was used to unlock the device in the past four hours; The device receives a remote locking command; Face matching failed 5 times; If you turn on the "light wake-up" function of iphone and put it in your pocket, your fingers will often touch it by mistake, and you may need to verify your password when you take it out. Press and hold any volume key and side key for 2 seconds at the same time, and then turn off/start the SOS emergency contact.
