How to Enable and Disable Two-Factor Authentication in iOS 11

26 November, 2017, by Tyler Greiner

“Two-step verification” is a popular concept of security that flawlessly suits the purpose of people that use a certain number of devices in spite of their iPhones or iPads. If a two-factor authentication is used, Apple will notify you with a small code of 6 digits for the Apple ID along with your personal password if you try to sign in from the new device. This plays a huge role in avoiding an unauthorized access to your relevant data.

Two-factor authentication is available within iOS 11. This is a suitable option that complements the extra level of security for your iPhone and guarantees its almost airtight security. This option remained intact with the emergence of iOS 11 and due to the explicit nature of iOS, it is relatively easy and simple to turn on. The process is quite simple, however, disabling the authentication will take a bit more time in order to ensure security.

Enabling Two-Factor Authentication

The activation of Apple’s two-factor authentication is performed using the settings of your iPhone. To turn it on, simply press on your name in the upper part of the main settings page, then select “Password and Security”. From there, click on the “Enable Two-Factor Authentication” tab.

Now you will be redirected to the page, which briefly explains this function, then press “Use two-factor authentication” just as soon as you read the details. You have an opportunity to either use the linked phone number that Apple will detect as linked with your account or put another one that you want to use.

Confirmation codes will be sent to the number that you have registered. In addition, you will be given two options as the text message version or a phone call on this number. As long as you only configure it, you are asked to enter a pass for your Apple ID, and then a 6-digit code. The function of two-factor authentication is fully turned on after successful input of the password.

Disabling Two-Factor Authentication

In accordance with security decisions, the process of disabling two-factor authentication in your iPhone is a bit more involved than enabling it. In a similar way, you simply cannot turn it off by setting the option of your own iPhone – instead of this you actually need to include Mac or PC in the process. In order to start, open the Internet browser in your own PC, then enter iCloud.com and sign in into your Apple ID.

Since two-factor authentication is enabled, iCloud, of course, will ask you to enter a 6-digit code before signing you in. Eventually, go back to your own personal iPhone and approve your own login by clicking “Allow” in the query request in order to get a code.

Using the six-digit encoding, enter it in the iCloud page in your PC browser. Next, push “Trust” in certain prompts. In order to finish the process of logging in, go to the main page of the iCloud account log. Afterwards, click on the “Settings”.

Now select “Manage” (located under the “Apple ID”) in the upper part of the settings page next to a name. You can switch to a different login page in order to renew the credentials of the Apple ID, and then another authentication code will come to your iPhone, as mentioned earlier. In each case, you will be taken to the page of your own account.

On the page “Manage your Apple ID”, click the “Edit” button in the right-side of the “Security” tab, which includes a pass, two-factor authentication, and all the trusted numbers of a phone.

On the page of security, go to the two-factor authentication tab and click “Disable two-factor authentication” in order to turn this feature off irrevocably.

Complete the process by clicking on the prompts in order to turn off this function. You will always have the opportunity to ask to make 3 new security questions until the device turns off, so continue and do this if you also haven’t done it. In the future, you will receive confirmation of the last changes with a notification that the two-factor authentication is disabled, then click “Finish” and sign out of iCloud account on your PC.
