What is Two-Factor Authentication (2FA)

Setting up Two-Factor Authentication

Once logged in, click on the “Security” tab near the top left of the dashboard and you will see your account security page. From there, you can select your preferred 2FA method.

Alternatively, the first time you login (and until your 2FA is set up) you will immediately see the 2FA notification pop up. From there, you can select your preferred 2FA method and follow the simple steps to set up.

Step 2. Click “Turn off now >>” and enter your 2FA code. To turn it back on again, simply click the “Security modifications” button and enter your 2FA code.
