I decided to give the "finger-touch" security lock a try. With that, I had to create a 6 digit back up passcode which I did and I clearly know what I put because it's the only passcode that I have always used to many years for almost everything. Turned out that I decided to deactivate the finger-touch security lock which also asked for my digit backup passcode as well. When I put it in, it will not work and indicated that it is wrong.
Please help me resolve this. Thank you!
You will need to restore the phone. You will need to know the AppleID and password associated with the phone.
