Google makes it much easier to use 2FA on your account

Google's two-factor authentication system (2FA) is a great way to secure your account, but in the past it has relied on a six-digit code or the presence of a USB security dongle. There's now a new method called "Google Prompt," which, like many other 2FA systems, just uses a simple push notification. When it's time to sign in, just enter your password, and you'll get a pop-up message on your phone asking you if you want to sign in. Press "yes," and you're in.

If you want to set this up yourself, just go to the "Security" section of your Google Account settings. Click on the "2-Step Verification" section, and there should be a new option called "Google Prompt." The option works on Android and iOS (provided you have an iPhone 5S or later). Of course Google recommends you have some kind of secure lock screen if you're going to use this feature, as is standard with other forms of phone-based 2FA. Enabling Google Prompt will automatically disable "Sign in with your phone," which used a similar prompt as a password replacement.

If you aren't using 2FA on your Google account, you have no excuse now, since the push notification makes 2FA faster and easier than ever.
