Understanding "Hide My Email" Option

What Happens When You Choose "Hide My Email"

If you select "Hide My Email" during Apple Sign-In:

Apple creates a unique relay email address (format: [email protected])
Example: [email protected]
This becomes your CENTR account email
CENTR never sees your real email address
All CENTR emails are forwarded to your real inbox automatically

Important to Know

For password resets: You must use your relay email, not your regular email
Finding relay email: Settings → [Your Name] → Password & Security → Apps Using Apple ID → CENTR
Contacting support: Provide your relay email to support when asking for help

For more details, see our article: "Understanding Apple Private Relay email issues"

Do I Need a Password?

No! When you use Apple Sign-In:

You don't need to create or remember a CENTR password
Your Apple ID is your authentication
Simply tap "Sign in with Apple" each time

Optional: You can add email/password login as a backup by contacting support at [email protected]. This lets you use either Apple Sign-In OR email/password.

Switching Devices

Apple Sign-In works across all your devices:

Same Apple ID: Use "Sign in with Apple" on any device where you're logged into your Apple ID
Different device types: Use Apple Sign-In on iPhone, then also on Android or Web - it all connects to the same CENTR account
No re-setup needed: Just tap "Sign in with Apple" on each device

Common Questions

Yes, contact support at [email protected] to link Apple Sign-In to your existing email account. This lets you use either login method.

If you used "Hide My Email," find your relay email in iPhone Settings → [Your Name] → Password & Security → Apps Using Apple ID → CENTR. See our article: "How do I find my Apple Private Relay email?"

Yes, you can switch to email/password login by contacting support. You can also add email/password as a backup option while keeping Apple Sign-In available.

What if I change my Apple ID?

Contact CENTR support if you change your Apple ID email. They can help update your account to use your new Apple ID.

Troubleshooting

Make sure you're signed into an Apple ID on your device (iOS Settings → [Your Name])
Update the CENTR app to the latest version
Try signing in on a different platform (web vs app)
Clear browser cache if using centr.com

This is usually due to Apple Private Relay email confusion. See our detailed article: "I can't access my account with Apple Sign-In" for complete solutions.
