Google has supported two-factor authentication for more than five years now, but the search giant is making it a little easier to use this week. Previously, you've 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. 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 prompt works on both Android and iOS devices, but you'll need to download the Google app for iOS to enable the new feature for iPhones. You'll 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. 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 pesky 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.
