IPhone and iOS 11: what is the mandatory two-factor authentication

This is a more secure security system, compared to two-step authentication, for all devices registered in the Apple ID

Presented a few days ago at WWDC, the annual conference that Apple organizes for its developers, iOS 11, now available in beta mode, has introduced several new features. One of the most important is the one that concerns the Apple ID, which will be automatically switched from two-step authentication to two-factor authentication.

Apple, in fact, as reported by numerous sources, in the last few hours has notified via email its beta testers - users who will have the opportunity to try a preview of the new operating system - of the upcoming change. This means that anyone who will install iOS 11 will only be able to use two-factor authentication, and no longer the two-step verification. The news will involve not only iPhone owners, but also Mac owners. Referring to the message sent by the Californian company, two-factor authentication, in fact, will be the only security system available on macOS Serra High.

What is two-factor authentication iOS 11

The new security system developed by Apple allows you to access your account from other devices safely. If you want to access your Apple profile from a new device (tablet or computer), in addition to the password, you'll have to enter the six-digit code that will appear on "trusted devices", which are those devices that have already passed the test of two-factor authentication.

The changes will take effect only for users who have activated on their devices two-factor authentication. For others, however, absolutely nothing will change. But what is two-factor authentication and what are the differences with the other security system? The two mechanisms work in much the same way. The first allows you to unlock a device by entering a password and a code received via SMS, a message that is likely to be intercepted by hackers before it reaches the recipient. Two Factor Authentication offers a higher level of security since the code is generated by the device itself and can work even without an internet connection.
