Google two-factor authentication is a method of confirming a user’s claimed identity by utilizing a combination of two different components. Google has supported two-factor authentication for more than five years now, but the search engine giant is making it a more easier to use this week.
Previously, you’ve had to manually enter a code from an authenticator app or via SMS, but now Google is introducing a new prompt that you can tap on your phone to approve login requests. It’s very similar to how Twitter’s two-factor authentication works, generating a notification that you accept from a phone and it approves the login attempt.
The new method works on both Android and iOS devices, but to enable the new feature in iPhones you’ll need to download the Google app for iOS . You’ll also need to enable this option by visiting the Google account page and navigating to Sign-in & Security > Signing in to Google > 2-Step Verification.
It works on both Gmail and Google Apps accounts, and once enabled you’ll receive push notifications if you try to sign into a Google account, and you won’t need to provide those annoying codes anymore. Multiple accounts can be supported through Android or the Google iOS app. Android users will need the latest Google Play Services to use Google prompt, and you can’t enable the prompt and Security Keys on a single account just yet.
