When I signed into an app using my “Apple” it assigned me a crazy email address I’ve never seen before instead of my Mac.com email address. How do I sign into the crazy email? I don’t even know a password to this new crazy email address?!? Help?!!

Hi Roxiestyle,

Welcome to Apple Support Communities.

It sounds like you have a few questions about signing in with Apple. When using this feature, you have the option to hide your email address using Apple's private email relay server that creates a unique email address that forwards to your personal email address.

There isn't a separate login for the unique email shown. Correspondence for the app will be forwarded to your personal email. This is a security feature that you can read about in What is Sign in with Apple?

Regards
