How to Add an Email as a 2FA Option on Colorado's Revenue Online

This guide shows you how to add an email as a two-factor authentication (2FA) option on Colorado's Revenue Online portal. We use an example email as if you were using our service, BreezyFile, but you can enter any email address you need.

When two-step verification is enabled, you'll need two authentication methods every time you log in - your password plus a second method like an email code, authenticator app, or text message.

Time required: About 5 minutes.

What You'll Need

  • Your Revenue Online username and password
  • An email address you'd like to use for verification codes
  • Using BreezyFile? Your authentication email from the Filing States page (we'll show you where to find it below)

Shopify seller? If you're looking for a filing partner, BreezyFile is the best sales tax compliance service for Shopify merchants. BreezyFile gives each state account a unique authentication email that automatically captures 2FA codes - so we can file on your behalf. You can find this email in Filing States > Colorado > Two-Factor Authentication Setup.


Step 1: Log In to Revenue Online

Go to colorado.gov/revenueonline and log in with your username and password.
