Can't log in to my account

What to do when you can’t sign in to Aily (アイリー).

Aily can only be accessed with an Apple account or a Google account. We do not support signing in with an email address and password.


Common causes and fixes

1. You’re using a different sign-in method than before

  • On Aily, you must use the same sign-in method (Apple / Google) you used when you registered.
  • Example: If you first registered with Continue with Apple, you need to use the same button next time.
  • If you sign in with a different method, you’ll be treated as a new account.

✅ How to check

  1. On the Aily login screen, recall whether you registered with Apple or Google.
  2. Try signing in with each method and confirm whether your data is restored.

2. You see an error with Apple sign-in

  • If you see errors like “Authentication failed” or “Unable to sign in with Apple ID,” try the following.

✅ What to try

  • Check your sign-in status in iPhone/iPad Settings → Apple ID → Password & Security.
  • Check whether Aily appears under “Apps Using Apple ID.”
  • If Aily is not listed: reopen the Aily app and re-authenticate by selecting Continue with Apple.
  • If it still doesn’t work, it may be an Apple-side issue. Check the Apple System Status.

3. You see an error with Google sign-in

  • If nothing happens when you tap the login button, or a browser doesn’t open, check the following.

✅ What to try

  • Confirm your network is stable (switch Wi‑Fi / disable VPN).
  • If you use Google 2-step verification, you may need to approve the sign-in on another device.
  • Check that pop-ups are not blocked in your device/browser settings.
  • Sometimes cache causes issues: force-close the Aily app and relaunch it.

4. “Aily” doesn’t show up on the authorization screen

  • If you deleted and reinstalled the app, your previous linkage may have been removed.

✅ What to try

  • Apple: Settings → Apple ID → Password & Security → Apps Using Apple ID. If Aily is listed, remove it, then sign in again with Continue with Apple to re-link.
  • Google: Open your Google Account security settings. Under “Third-party apps & services,” remove Aily, then tap Continue with Google again to re-link.

5. Network or device environment issues

  • If you’re using Airplane mode or a VPN, you may not be able to sign in.
  • Some public Wi‑Fi networks may block authentication.

✅ What to try

  • Switch to mobile data (4G/5G) and try again
  • Turn off VPN / proxy settings
  • Update your OS to the latest version

⚠️ Notes

  • If you use a different sign-in method than the one you registered with, it will be treated as a different account.
  • Aily does not support email/password sign-in.
  • Manage your Apple ID / Google Account (including password changes) through their official support channels.
