First of all, a concept needs to be clarified: "two-factor authentication" is not "two-step verification" .

The difference between "two-factor authentication" and "two-step verification" Although the two verification methods have the same general principles, they still have significant differences in their specific implementation methods. 1. How to activate "Two-step verification" can only be activated on the management page of Apple ID.

"Two-factor authentication" can only be enabled in the iCloud account management page of iOS 9.3 or OS X 10.11.4. 2. When "Two-Step Verification" is enabled for device registration, the system will require you to send a separate verification code to each iOS device with "Find My iPhone" turned on, in order to set the corresponding device as a "Trusted Device" , and use them to receive verification codes.

When "Two-factor Authentication" is enabled, the system will automatically set all devices logged into iCloud as "Trusted Devices". Both methods require manual verification of the "Trusted Phone Number".

3. Recovery Key "Two-Step Verification" will generate a string of "Recovery Keys" as a back-up method for restoring account access. "Two-factor authentication" does not generate any recovery keys.

4. Verification process When logging in to Apple ID on an untrusted device or browser, both verification methods will require you to enter an additional verification code to confirm your identity. After entering your account password, "Two-Step Verification" will ask you to select a "trusted device" or "trusted phone number" to receive a four-digit verification code.

"Two-factor authentication" will automatically send login reminders to all "trusted devices". You can also manually choose to use your mobile phone number to receive verification codes. Different from "two-step verification", the login reminder not only contains the verification code, but also displays the approximate geographical location of the account login. The length of the verification code has also been extended from four to six digits.

Users can choose whether to allow this login attempt on any device. Select "Allow" and the system will automatically display a six-digit verification code. "Do not allow" will directly deny the login. Once selected on one device, login reminders on other devices will automatically disappear.

5. The device that receives the verification code "Two-Step Verification" can only send verification codes to iOS devices. "Two-factor authentication" can send verification codes to both iOS devices and Macs.

6. Use offline. When all "trusted devices" and "trusted phone numbers" are offline, "two-step verification" will not be available, which may cause trouble for your login. . "Two-factor authentication" can generate verification codes offline on "trusted devices", greatly simplifying the user experience.

If you want to log in to your Apple ID on a device with versions prior to iOS 9 and OS X El Capitan, you need to manually generate a verification code and enter the account password in the password field of the older device, followed by six digits Generated verification code. 7. Change of security information After "Two-Step Verification" is activated, you can only modify the security information including "Trusted Devices" in your Apple ID.

"Two-factor authentication" allows you to modify it directly on the account management page on the device. 8. What to do if you forget your password "Two-step verification" requires you to have any two of your account password, recovery key, and a "trusted device" that can receive the verification code to access your Apple ID.
