Hi yendaliz,
Welcome to the Apple Community.
What’s happening with your Apple ID?

Your Apple ID is the account you use to access Apple services like the App Store,
Apple Music, iCloud, iMessage, FaceTime, and more.
It includes the email address and password you use to sign in,
as well as the contact, payment, and security details you use across Apple services.
How to create your Apple ID if you do not have one::
