Login to Apps using a different Apple ID
On my iPhone. I have signed up on an application using my Apple ID.
Now my partner has an iPhone and has her own Apple Account. I asked her to download the app and I would login to the App using my Apple Credentials.
it looks like I can’t do that since when I try to Sign In with Apple ID it always asks about my partner’s account.
The question is how can I login to an App using my Apple ID on my partner’s iPhone?
