Ok so my cousin had an Apple Watch then she gave it to me because her phone completely broke and she can’t use it and to set up the Apple Watch we need her Apple ID password but she doesn’t know it
How do I link my Apple ID to the watch app on my iPhone to set the Apple Watch up because she doesn’t know hers and it won’t let me sign in without her Apple ID but she can’t get in her phone to see it because it’s broke
