How can I log in if I can't receive the verification code of Apple's double authentication?

Use the logged-in Apple device instead of the authentication method.

1. Use alternate authentication mode: When setting up two-factor authentication, you can choose alternate mobile phone number or alternate email address to receive the verification code in addition to your mobile phone number.

2. Use the logged-in Apple device: Another Apple device has logged into the AppleID, and you can use this device to receive the verification code. Open the settings on the device, select the AppleID, enter the password and security options, find the two-factor authentication settings, and then select the get verification code option.
