Since five years, Google has supported a two-factor authentication for greater security of users. Now the search giant is making it a little easier to use this security feature; previously, you had to manually enter a code from an authenticator app or via SMS, but Google is introducing a new prompt that you can tap on your phone to approve login requests.
The new prompt works on both Android and iOS devices, but you will need to download the Google app for iOS to enable the new feature for iPhones. You will also need to opt-in to this new Google prompt by visiting the Google account page and navigating to Sign-in & Security > Signing in to Google > 2-Step Verification.
The feature works on both Gmail and Google Apps accounts, and once enabled you will receive push notifications if you try to sign into a Google account. However, you will no longer need to copy the code from your mobile and paste it into the account you were trying to login; instead you can approve the login request by tapping the notification on the phone. Multiple accounts can be supported through Android or the Google iOS app.
