Locking iPhone with Siri

A little hint for those who want to prevent their phone from using Face Recognition and requiring a passcode.

Just say "Hey Siri, Who's phone is this?"

You can also close your personal contact card by saying:

"Hey Siri, Goodbye."

Your phone will now be locked and a passcode will be required to unlock it.

You may now delete my post asking if anyone knows how to use Siri to lock your phone.

Bye for now!
