Apple Two-Factor Authentication Error

Issue: When attempting to push a build in Adalo, you may encounter the following error: Verification codes can’t be sent to this phone number at this time. Apple has phased out SMS-based authentication as a primary method for Two-Factor Authentication (2FA) to improve security.

Cause: This error occurs when there are no trusted Apple devices associated with the account that can receive verification codes. Apple requires at least one trusted device to authenticate via Two-Factor Authentication (2FA). As a result, users must have at least one trusted Apple device linked to their Apple ID to receive verification codes. If no trusted devices are available, authentication will fail.

Resolution: To resolve this issue, you must add the developer email account to an iOS device to enable 2FA code reception.

1. Open Settings on an iOS device.

2. Navigate to Apps > Mail.

3. Select Mail Accounts.

4. Tap Add Account > iCloud.

5. Sign in with the developer email account associated with your Apple Developer account.

6. Once the account is added, the device should become a trusted Apple device.

7. Attempt to push a new build in teh Adalo Builder.

After completing these steps, you should be able to receive the required verification codes and proceed with authentication successfully.
