Seven Websites That Support Two-Factor Authentication

The modern Internet landscape holds no shortage of security risks for users. The lynchpin of security for hundreds of millions of Internet users is typically the simple username and password combination, which provides access to sites and protects user information. It's a lynchpin that attackers know well, which is why phishing and other forms of credential attacks are aimed at stealing usernames and passwords in a bid to exploit user data. One technique that has emerged to help reduce the risk associated with the username/password combination is the use of two-factor authentication. With the two-factor authentication approach, a second password (or factor) is required, for a user to be able to log in to a site or service. Even if an attacker compromises a username and password, the attacker will not be able to gain access without the second factor. While a simple user password is something that the user needs to remember, the second factor relies on something that the user must have (i.e., a device or a token). In many cases, the second factor is delivered by way of the user's smartphone, either by Short Message Service (SMS) or with a two-factor application like Google Authenticator. Here, eWEEK looks at seven major sites that support two-factor authentication today.
