What is two-factor authentication (2FA) and how do I enable it?

Two-factor authentication (2FA) provides an additional layer of identification verification when you log into a website.

After entering a valid username and password, 2FA will prompt for a one-time code for access. This one-time code is usually obtained via SMS (text message), however there are other applications that can generate one-time 2FA codes, and even devices including USB dongles.

Beginning March 31, 2020, our upstream provider Rackspace will require 2FA for access to all Email Admin panel accounts.

If you do not want to use SMS, we recommend an app called Authy, which is a free authenticator that you can use from any device, including your desktop, laptop or mobile  phone. You can also use it across multiple devices for the same account.
