If your account shows an email ending in @privaterelay.appleid.com, it's because you chose Apple's "Hide My Email" feature when signing up with Apple. This is completely normal and doesn't affect your account.
How it works
Apple creates a unique, random address that forwards to your real inbox, so RedotPay never sees your personal email.
Any message RedotPay sends to that address—including verification codes and account updates—is automatically forwarded to your regular inbox by Apple.
What this means for you
Logging in: Keep using the [Continue with Apple] button to access your account. Because your account is tied to Apple sign-in, logging in with a password won't work.
Receiving messages: You'll still get all important updates and verification codes in your normal inbox, so there's nothing you need to change.
