Google has recently enabled two-factor authentication for Google products like Gmail. What is two-factor authentication? It means that in addition to providing your password, you need to provide a random verification number that Google will send to your phone, either via an app, a text message, or an actual phone call. Thus, to log in, you need two things: a password and your phone. With only one or the other, you can’t get it. This is much stronger than a password alone, which is why some banks have been moving to two-factor authentication for customers. Google’s decision to enable it for email, and for just about everybody with an account, is certainly groundbreaking.
