Google Authenticator is a mobile app that provides users with the ability to create 2-step verification when signing into their Google account from a location other than their trusted computer. Whether in a public place or using a friend’s computer, Google Authenticator makes logging in more secure and harder for others to hack your account, even if they find out your password.
Google Authenticator makes logging in almost anywhere safe by using two different things: your password, which you know, and your phone, which you have. Authenticator generates a code that will appear within the application that will be used to login to your Google account from a public place after entering your password. Because of this, even if your password is stolen or cracked, your account cannot be entered without your phone.
