iPhone suddenly asks for 6 digit code
My wife's iPhone suddenly asks for a 6 digit passcode. We have never set up a 6 digit passcode on this phone. Now we are locked out fo her phone and since we don't know of any passcode we don't know what to enter.
Restarted the phone, but still needs a 6 digit passcode to unlock the phone.
What is going on here? She was playing Pokemon Go, switched off the phone and suddenly this happened.
It is an iPhone SE 2020. Please help!
iPhone 11 Pro Max, iOS 16
