It's important you set it up on all your accounts. Here's how to set up 2 factor authentication for a Google account, and learn why it's so useful. Why Is Google Two Factor Authentication Useful? Google was one of the first companies to introduce 2 factor authentication to its services. It requires people logging in to have access to a physical device like a smartphone, as well as virtual passwords, and is typically one of the best ways to prevent unwanted access to precious accounts. It makes things much harder for anyone to access your content and only takes seconds to set up and use. How Does Google Two Factor Authentication Work? Google two-factor authentication adds an extra layer of security by requiring you to have both your password and a special security key to access your accounts. This is generally done by Google sending you a verification code that's specific to your account. They're sent to your phone via text, through voice call, or via the Google Authenticator app, with each code only usable once. What Google Accounts Does Google 2FA Work With? Two factor authentication via Google doesn't only apply to the Google services you use, but numerous other companies, too. Some of the websites that also use Google's two-step verification services include: AmazonDropboxEvernoteFacebookInstagramLastPassOutlook.comSnapchatTumblrWordpress How to Turn on Google Two Factor Authentication A few simple steps are all that lie between you and an extra layer of security for your account details.

Alternatively, you can select Add Google Prompt so you receive a prompt on your phone instead of verification codes. Choose from one-off printable backup codes, a Google prompt, or to install the Google Authenticator app to your phone. It's also possible to add a backup phone in case you lose your phone, as well as request a physical security key that plugs into your computer's USB port.
