I replaced the battery in an iPhone 6 that was given to me, and now it
Why does iPhone 6 have a 6 character passcode after battery replacement? The original passcode is 4 characters. I replaced the battery, then let it drain and when I powered it up again it has an entirely different 6 digit passcode. What’s up with that? The previous owner upgraded at a Verizon store to an iPhone 8. The Verizon store said they wiped the 6 clean, and then it was given to me. Battery replacement worked fine, but now it magically has some unknown 6 digit passcode.
Anyone have any insight?
