How to configure two-factor authentication for iOS and macOS


One of the easiest ways to protect your data is to enable two-factor authentication. The Lifehacker will tell you how to do it to protect yourself.


To enable two-factor authentication, the device must work at least on iOS 9. The required actions may vary slightly in different versions of the mobile operating system.

If you are using iOS 10.3 or higher, go to settings, click on your name and select “Password and Security”. So you can enable additional protection: the system will send a text message with the code every time you try to log in.

If you have iOS 10.2 or earlier, then two-factor authentication can be found in the iCloud → Apple ID → “Password and Security” section.


You will need the version of the operating system El Capitan or higher.

Click on the apple icon in the upper left corner of the screen, select “System Settings” → iCloud → “Account”. You can speed up the process by entering the word iCloud in the Spotlight search. Then click the Security icon and enable two-factor authentication.

You can choose how Apple will confirm the input: using a six-digit code in the message or a phone call.


You can login to Instagram through the browser, but configure two-factor authentication – only through the mobile application. Go to the profile and open the menu with the button in the upper right corner. In the “Account” section you will see the required option. Activate the “Require security code” switch. Now every time you sign in, you will receive a message with the code.


Via the menu in the mobile application or in the browser version, enter the settings and select the ” Security and Login ” item . In the section “Use two-factor authentication” you can register a phone number. At every attempt to enter the social network, the code will come. There is an option to have Facebook send a push notification to confirm or reject the entry.

Here you can also configure the security key for logging in using the USB keyfob or NFC beacon. And for travel abroad, where there is no access to the Internet, excellent recovery codes. They can also be generated in this section.

If you prefer not to use additional security measures every time you log in from the same device, you can add it to the list of authorized inputs.
