Two Factor Authentication

How it works

Two-factor authentication adds an additional layer of security by introducing a second step to your login. It takes something you know (i.e.: your password), and adds a second factor, typically something you physically have (such as your phone). Since both are required to log in, in the event an attacker obtains your password, two-factor authentication would stop them from accessing your account.

Why do you need it?

Passwords are increasingly easy to compromise. They can often be guessed or leaked, they usually don’t change very often, and despite advice otherwise, many of us have favorite passwords that we use for more than one thing. So Two-factor authentication gives you additional security because your password alone no longer allows access to your account.

How does it work?

There are many different options available, and in we support more than one so you have the choice. But one of the most common and simplest to use is time based one-time passwords. With these, in addition to your regular username & password, you also have to enter a 6 digits code that changes every 30 seconds. Only your token device (typically a mobile smartphone) will know your secret key, and be able to generate valid one time passwords for your account. And so your account is far safer.


Duo Security enables your users to secure their logins and transactions using their smartphones. The Duo Mobile smartphone application is free and available on all major smartphone platforms, and allows users to easily generate passcodes without the cost and hassle of hardware tokens. iPhone, Android, BlackBerry, and Windows Phone users can use Duo Push which “pushes” login or transaction details to the phone, allowing for immediate, one-tap approval.

Older devices like cellphones and landlines are also fully supported. Duo can send passcodes via text message, or place a phone call ” users just press a button on their keypad to authenticate.
