Google authenticator – Securing your Google accounts and your favorite Linux
May 26, 2012 2 Comments
Google authenticator is a Google project implementing TFA (Two Factor Authentication). TFA is a way (as the name suggests) to authenticate with two factors. When you authenticate to GMail with only a username and password, that’s called a one factor authentication (the password). If your password has been compromised, anyone who knows your password can gain access to your GMail account, accessing all your private data there.
