update iOS 11 can't log in Apple ID

I solved the problem.

1. enter 'App Store' app.

2. try to log-in with your ID which is called X at the App Store app.

3. You can see a different Apple ID in the App Store id section after the 'could not sign in'. I will call the ID as Y.

4. press home button.

5. enter 'settings'-'iTunes and App store'.

6. log in with Y id and Y password at the Apple ID. You have to know the Y password.

7. tap Apple ID and logout.

8. log in with X id and X password at the Apple ID.

It works for me.

Have had the same problem for months. Went to apple store and they say "I need a new phone". Anyways, apple support via phone was most helpful after a senior advisor helped out and problem was resolved. **Back up your phone, plug in iphone to computer and then "restore Iphone", then when it prompts you...after it resets after its been "restored", proceed to "restore from xyz backlup" from your most recent backup; all of this was completed within Itunes on macbook. I don't use Icloud, but I'm sure thats fine. I have an iphone 6 (feb 2015) and basically the software was too old for anything to function properly. "Restoring iphone" downloads the updated software to your phone and then restoring it from your backup downloads all the aps etc to you phone and updates them properly. Other's recommendations on this blog did not work for me, even the one that seemingly worked for everyone else (signing into an old apple id, logging out of it, and then logging back in with the main apple id)--that didn't work for me. If that doesn't work for you then the proposed method may work. Good luck!

Try this- it worked for me. Go into settings, then RESET, then "DELETE NETWORK SETTINGS" and force restart the phone. When it comes back up it SHOULD work. I had same issue and that solved it.

Hi

Try a reboot press the power button down & menu button hold both down until you see apple logo this can take 30 seconds.

If you have a iPhone 7 /8 press power button down & side down volume button.

Then go to iTunes main page bottom of page apple I'd delete all I'd Then add back again.

Cheers

Is your "emergency/backup email address" maybe the main email address of a different Apple ID? In my case it was, and I solved this issue (after hours trying) by logging in with the old/emergency mail address (which required a different password) and then logging out and logging in with the new one.

OMG! It now works!

I tried the above, then I restored via iTunes but --- I did an iCloud backup restore rather than restoring from iTunes. I logged in with my main account, and ... it now downloads apps again! I am so happy! Thank you erbei!

I was unable to proceed and unable to perform any activity. Then I selected "Don't have an Apple ID" and moved ahead by selecting that I don't want to use Apple ID. After I reached phone's home screen it automatically prompted me for Apple ID and accepted the password.

11.2 update fixed my issues with the whole Apple ID conundrum. Unfortunately, I was months without being able to access anything on iTunes or the App Store, but better later than never I guess....thanks apple

Try turning off your wifi and logging in. Worked for me.

Could you check step 5?

You should log in at 'setting'-'iTunes and App Store' menu.

I hope it will be helpful.

I spent 3 hours on support yesterday doing bug chasing and got escalated right to the top with this issue. Unfortunately it's a bug and we'll just have to wait for an update. Fortunately I see there's an update! So I will report back to see if it fixes this problem.

I have this issue too, and can't buy in-app purchases because of it, or download new apps. When I'm in the App store and look at my account, it has me as being signed in with my backup/emergency email account. When I click on that to view the Apple ID, it just takes me to a blank screen.

I've tried, to no avail:

1) changing date to last year, as apparently fixed this issue in older phones. The server now checks this and boots you off before it does anything.

2) changing my payment details and getting it to re-auth them. This seems to make the ID fine in the Settings area, but when I go back into the App Store, it fails again and I have to re-authenticate, at which point it gives me the "Could not sign in" message. When I go back into the App store afterwards, it has the emergency/backup email address there again.

This is very frustrating!

Don't do this - you'll lose access to all your apps as you'll get into a login loop and none of your apps will be able to download from the app store/icloud. This happened to me! Wait for the update that will fix it instead.

Same issue not signing Apple ID after updating to iOS 11.0.3
