I always use a 4 number password on my 6plus. all of sudden it happened, the passcode become 6 number one afternoon when I use (5mins before it still OK, 5 min later become 6number). I never change it, and no one else did it (it`s with me,and no one know my passcode). I have no idea what is the 6 number passcode. I can only use touch id to login.
iPhone 6 Plus, iOS 9.2.1
Updated my phone last night. Everything was fine until my phone battery died about 15 mins ago. Now it wont accept the same passcode ive had for 10 months.
Has anyone resolved this issue or do i have to reset my phone...?
I'm afraid this may be your only option:
Who have you lent your phone to recently?
No one. That just happened in a sudden. I was using it with my passcode (4 numbers) 5min before. Still in my hand. No one know my passcode, and it was IN MY HAND! Then it become 6 number passcode....I can`t believe it
Did you update it?
Yes updated two or three days before.
This happened to my husband last night just before an important work trip and left him unable to access his work email account and some contacts. The general consensus is that this cannot happen but it did. Hope you got it sorted. Did you apply a software update before it happened?
yup, I did the update. Since I can still login with touch ID, so I backup my iPhone with iTunes. Then erase the phone, and restore all the data. It`s so wired, but once I restored with the new iOS, I find it can't set a 4 digit passcode anymore. Only "6 digit passcode" or "number plus letter" passcode, no more 4 digit passcode. I guess it`s because the new iOS.
Thanks for your reply. Thought we were going mad with all the posts saying it was impossible but it did happen and at the most unfortunate time. Glad it seems to be sorted.
You can go back to a 4-digit passcode if you wish. Go to Settings > Passcode and select options as required to change your passcode. Before you actually enter the new passcode, select "Passcode Options." That'll do it for you.
I know how to set the passcode, but just no 4-digit passcode option.
There is only one option when selecting "passcode options" either "custom alphanumeric code" or "custom number code" . Neither of them allow a 4-digit code, I tried, then showed "the passcode must be longer". So no more 4-digit passcode on my phone. I guess it`s a bug, all of a sudden 4-digit code disappeared on my iPhone, my passcode changed from my 4-digit code to some I don`t know 6-digit code. After erase everything and recover with the new iOS, there is still no more 4-digit code option.
Yeah, when I bring it to Apple store. The apple guy never believe the passcode will change by itself, they think there must be someone did it. But i just happened in my hand.
My phone does not allow give me passcode options
I got this problem too with my IPAD mini 3. How to recover this? What wrong? Is this call VIRUS?
passcode changed itself!!!
