Two-Factor Authentication

As the always-online world has continued to become an ever more dangerous place, the need for user authentication methods other than the old, not-so-reliable username/password combo has become evident.

Logins via the long-accepted username and password method have grown increasingly insecure. Unfortunately, many users make use of the same username and password or rotate through a small number of login combinations.
