Understand two-factor authentication

Two-factor authentication (also known as 2-factor authentication or simply 2FA) adds a second level of authentication to an account login. Logging in with just your user name and password is considered single-factor authentication. Adding another secure login factor is known as two-factor authentication.

Some state Departments of Revenue (DOR) websites use two-factor authentication as an added layer of security. Because our filing team is required to log into the state's websites, they need access to that authentication code.

To ensure that both the customer and Avalara have the access to the DOR website, we require the customer to use a specially provided email address for their two-factor authentication, which forwards the security code to both Avalara and the customer’s email on file.

NOTE: If you do not receive the security code, please contact Avalara support.
