Use iPhone as a Google Security Key for 2FA

You’ve probably heard by now that SMS based two-factor verfication (2FA) is not as secure as we had thought as researchers have shown how it is possible to hijack a text message. But as we reported a few days back, the good news is that your iPhone can now be used as a much more secure Google security key. In this article, we will show you how to use your iPhone as a physical secure key for 2-step verification for your Google Account.

The Google Smart Lock feature makes use of the iPhone’s secure enclave to turn your iPhone into a secure FIDO2 key. According to Google, security keys are more secure second step. You can buy Titan security key kit from Google’s Play Store, but you can now turn your iPhone into a Google security key. It is amazing how we can use our iPhone for so many things.

So you can enable this feature with the following iPhones and iPads that come with Touch ID or Face ID:
– iPhone 5s, iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone 7, iPhone 7 Plus, iPhone 8, iPhone 8 Plus, iPhone SE, iPhone X, iPhone XS, iPhone XS Max, iPhone XR, iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max.
– iPad Pro 12.9-inch (1st generation), iPad Pro 9.7-inch, iPad Pro 12.9-inch (2nd generation), iPad Pro 10.5-inch, iPad Air 2, iPad Air (3rd generation), iPad mini 4, iPad mini (5th generation), iPad mini 3, iPad (2017). iPad (2018), iPad (2019), iPad Pro 12.9-inch (3rd generation), iPad Pro 11-inch

 

Before you enable your iPhone or iPad as the secure key, it is important to note that you can still use the other mechanisms like SMS, authenticator apps like Authy (App Store link), Google Authenticator (App Store link). Your iPhone or iPad can be used a secure key only on Chrome at the moment.

I would recommend using your iPhone rather than an iPad, which is your primary phone as you will carry it where you go, as you might need it to access your Google Account.
