The other day I downloaded a new version of the iPhone or iPad security app iVerify, and it offered a new tip for securing your device that I'd not considered before.
Here's how to find an effective Virtual Private Network service for both iOS-powered iPhones and Android smartphones.
Read nowIt involves Face ID and the fact that it can have more than just your face enrolled.
Face ID offers a super-fast and convenient way to unlock modern iPhones and iPads, and it's super secure.
But it's only as secure as your passcode.If someone secretly knows your passcode (maybe they've shoulder-surfed you to get it), they could add their face to your iPhone or iPad and could be unlocking your device with the same ease that you're unlocking it.

OK, so how do you tell if someone else's face is enrolled with your Face ID?
TapSettings > Face ID & Passcodeand enter your passcode.
If you see the option toSet Up an Alternative Appearance, then there's only one face enrolled, and you're OK.
Only one face enrolled in Face ID
However, if that option is not visible, there are two faces enrolled (or perhaps you enrolled your face twice). If this is that case, and you've not set up your device so someone else can access it, tap onReset Face IDand go through the enrollment process again (it takes seconds).
Two faces enrolled in Face ID
I also recommend -- highly recommend -- that you change your passcode. To do this tapSettings > Face ID & Passcode, and enter your passcode, and then tapChange Passcode.
It's quick to check and quick to fix. As to whose face was set up as the alternative appearance, there's no way to know (unless you go pointing your locked iPhone at people and see if it unlocks) because the face isn't stored, only a digital representation, and this is locked away in Apple's Secure Enclave chip.
I recommend installingiVerify . It's a very handy security app that's packed with information on how to make your iPhone or iPad more secure.
