"Sign in to facetime" keeps appearing, and requesting a login

Go to Settings/FaceTime, log out, and log in with your Apple ID. Do the same for Settings/Messages.

No, you just deleted the Apple ID from your phone. You can create your own Apple ID now and log into iCloud with it. You can keep the same Apple ID as your daughter for Settings/iTunes & App stores; that will allow you to share music and apps.

I'm traveling abroad and, for saving battery, i turned off wi-fi and I have no connection to an internet provider. Now it keeps nagging for my AppleID password to connect to Facetime and won't let me access the Settings on anything else! I know that when I come back to US I'll have my LTE connection and will be able to enter my AppleID password and access my phone normally, but this is **** frustrating! IOS should recognize that if the phone has no internet access to login to the user's account, it won't try to use Facetime or any other app that may require an AppleID! How can I fix this situation... hard resetting my device? If so, how do I do it since I have no iTune around.

I am now having the same problem - "sign in to face time" keeps appearing, and the email account originally used was an old one that I do not have access to. I have tried your fix, but I cannot get into Face Time or Settings because the sign in request keeps popping up within 1 second. How can I access this not on my phone, since my phone cannot be used anymore... Right now, I am on vacation, and without my phone, I cant even call apple support! Help please!

My 11 years old solved this problem to me! He followed one of the solutions above by hitting the Cancel button and, before it popped back again, he could navigate thru the Settings and, after the following popup, he hit Facetime and then he turned it off!

I entered the password correctly, but it comes back saying the password is incorrect! I can confirm this by using a laptop with internet connection and the same username/password get accepted by logging iTune or even this website.

It turns out that the phone does not have any data connection: no wifi, no cellular turn on.

The ugly thing about this is that Apply/Facetime wrongly shows the message. Why doesn't it say "There is no connection to verify the username/password?"

STUPID!

After I quickly tab "Cancel" and able to turn on cellular network, enter the same password again, and the popup goes away.

Perhaps as an aside, but don't forget that if you have two-factor authorization on for your Apple ID, you may need to create an app specific password for FaceTime.

First sign out of FaceTime. Then, In settings date and time, go back, for couple of months or year and popup will disappear!

Worked for iphone 5 ios 8.1.3 and ipad 2 iOS 7.1.2 and probably all the other versions, too. Credit goes to RossoNero1502991 who posted his answer on youtube first and which I expanded to the iPad. You need to be quick and probably try tens of times to get to the screens while getting interrupted by the popup. Don't despair, just keep going.

Oh ****.. I did that, the messages eventually stopped appearing, and now "Sign In to iCloud" dialogs start appearing !!!!

Come on Apple, it's 2015... add some user-friendliness !!

Add a "Stop bl**dy nagging me" checkbox to this dialog.

Perhaps I don't want to sign-in to iCloud or FaceTime this particular time. Perhaps I just want to use my current set of apps, without being nagged every 10 seconds with a modal dialog.

I Don't have my iPhone connected to data it's not letting me sign in to wifi either so none of the solutions here are helpful to me either :-(

THIS JUST SAVED MY SANITY! Thank you so much!

Thank you! This was happening on my mother's macbook air & I was going nuts... you rock Mr. Finch!

Happy New Year & Many Thanks!
