How do I sign into another Apple ID?
how do I sign into another apple id on my iphone 6s? example: the default ID showing up is email1@icloud.com and I want to sign in using email2@icloud.com. I can't change the default ID when signing in on the phone. email2@icloud.com is already a valid apple account which I know the password for. email1@icloud.com is currently the user ID showing up when signing into the iphone but I don't know the password and I can't change the user ID to sign into the other one.
