The article provides an overview of Apple ID two-factor authentication.
When initially using the Manage iCloud feature within FoneTool and inputting your Apple ID account password to bind it, you will receive a prompt for a two-factor verification code (as depicted in the screenshot below). This might prompt inquiries regarding the necessity for this dual verification process within FoneTool. What is its purpose? This article is designed to introduce you to the concept of two-factor authentication for Apple ID.
Brief Introduction to Two-factor authentication：
Two-factor authentication is an additional layer of security provided by Apple for users' Apple IDs, aimed at ensuring that only the account owner can access their account, even if others know the password. When logging into Apple ID for the first time on a new device or web page, it requires both the password and a six-digit code that automatically appears on trusted devices. As knowledge of the password alone is insufficient to access the account, two-factor authentication significantly enhances the security of your Apple ID and the data stored through Apple. Therefore, when adding your Apple ID for the first time in FoneTool, this verification code is also required.
How to Enable Two-Factor Authentication for Apple ID:
If you haven’t activated two-factor authentication for your Apple ID, you can do so directly on your device or through a web browser:
On iPhone or iPad: Go to 'Settings' > '[Your Name],' then tap 'Password & Security.' Tap 'Turn On Two-Factor Authentication.' Proceed by tapping 'Continue' and follow the on-screen instructions.
On Mac: Choose the Apple menu > 'System Preferences,' then click your name. Click 'Password & Security.' Next to 'Two-Factor Authentication,' click 'Turn On,' and follow the on-screen instructions.
On the web: Visit appleid.apple.com and log in using your Apple ID. Answer your security prompt questions, then click 'Continue.' When prompted to update your account security, click 'Continue.' Tap 'Update Account Security' and follow the on-screen instructions.
Tip: If your Apple ID already has two-factor authentication enabled, you cannot turn it off. However, if you inadvertently enabled it, you can disable it within two weeks of registration. Disabling two-factor authentication will lower the security of your account, and you won’t be able to use features that require a higher level of security.
First Time Logging into Apple ID on a New Device:
When logging into a new device or webpage for the first time using your Apple ID username and password, you might receive a notification on a trusted device indicating that someone is attempting to log in using your Apple ID. This notification may include a map displaying the approximate location of this login attempt. The location is based on the new device's IP address, which may reflect the network the device is connected to rather than the exact physical location. If you recognize the login attempt as your own but cannot identify the corresponding location, you can still tap 'Allow' and view the verification code. If the login attempt isn’t initiated by you, tap 'Don't Allow' to prevent the login attempt.
Entering the verification code on a new device or webpage implies your acknowledgment and trust in the device you are logging into. The system might also require you to input the password of a specific device to access any end-to-end encrypted content stored in iCloud.
After logging in, the system won’t prompt you to input the verification code on that particular device again unless you completely sign out, erase device data, or for security reasons need to change the password. When logging in through a webpage, you can choose to trust your browser, eliminating the need to input the verification code again on the respective computer for 30 days.
Tip: If you're attempting to log in but don’t have any trusted devices nearby to display the verification code, you can tap 'Didn't Get Verification Code' on the login screen. From there, choose to have the verification code sent to one of your trusted phone numbers. The text message may contain an additional domain verification line displaying symbols like '@' sign, the website name, and your verification code (e.g., '@icloud.com #123456 %apple.com'). Alternatively, you can directly obtain the verification code from the 'Settings' on a trusted device."
