This video will show you how to fix this issue: You have multiple Apple iOS devices (iPhone, iPad, iPod Touch) or a combination of these, and although you can log in using your Apple ID on the newer iOS device, every time you try to log in using your Apple ID on the older iOS device, you are being told that your Apple ID or password is incorrect, despite the fact that you are certain that you are typing it in correctly. The reason that this is happening is because newer Apple iOS devices use two factor authentication (when you try to log in using your Apple ID on a newer iOS device, on your device’s screen a popup, independent of any app, comes up on screen letting you know that an Apple ID sign in request has been made using your Apple ID, and asking you if you would like to accept or reject this login attempt). If you use (or have already used) your Apple ID on an iOS device that supports two factor authentication, Apple automatically and irrevocably enables two factor authentication on your Apple ID account. The problem here is that older iOS devices do not recognize two factor authentication requests, and therefore do not display this 2FA popup when you do try to log in using your Apple ID on an older iOS device.
If you have access to both the newer iOS device (that supports two factor authentication) as well as the older iOS device, both connected to an Internet connection, when attempting to login using your Apple ID on the older iOS device, the 2FA popup should display on the screen of the newer iOS device. Should you accept this connection attempt on the newer iOS device, you will be given a temporary 6-digit number. On the older device, re-type your password as you know it, but instead of tapping OK at the end of your password, after your password type the 6 digits from the verification code that was displayed on the newer iOS device screen (without spaces). Once your password and 6 digits from the 2FA screen have been typed, then you can tap OK and you should be able to login to your Apple ID on the older iOS device. For example, lets say that my Apple ID password is applepie and the temporary 2FA number that I had just received was 126 978. On my older Apple ID device, my password would not simply be applepie, but in this case would instead be applepie126978
Of course, apps that have already been downloaded in the past can be redownloaded from the App Store without the need for two factor authentication. Previously downloaded apps are found under APP STORE – UPDATES – PURCHASED. Also, you can download an app on the newer iOS device that uses the same Apple ID, and once the download has been accepted on the newer iOS device, then on the older iOS device this app should also appear under APP STORE – UPDATES – PURCHASED. Should a compatible version of the app in question be available from the App Store, then you can download this app from this PURCHASED list on the older iOS device without having to go through two factor authentication.
