Domain Allowlisting

Trello Enterprise

As part of our Single Sign On (SSO) feature for Trello Enterprise, we offer the option to allowlist the domain(s) associated with your company.

Allowlisting will cause new users who sign up with an email address at your allowlist domain(s) to be routed through login with your SAML Identity Provider (IdP) automatically. It won't impact existing Trello users.

How it works:

  1. If you have a standalone Trello Enterprise, work with Trello Support to configure SSO and allowlist yourdomain.com.
  2. A new hire signs up to Trello on our main signup page using their-name@yourdomain.com as their email address
  3. When they click the button to complete sign up, Trello will redirect them to the IdP associated with your company
  4. Once they've logged in to the IdP, they'll be redirected into their Trello account

We don't recommend domain allowlisting if your IT Team will be provisioning Trello only to select users in your IdP (as those users will see an error on signup). 


Atlassian Organization

If you're an admin of an Atlassian Organization, we also offer allowlisting a domain in the Admin Hub and SSO with Atlassian Access.

How it works: 

  1. Your Atlassian Org Admin will claim your domain within the Atlassian Org Admin Hub
  2. A new hire signs up to Trello on our main signup page using their-name@yourdomain.com as their email address
  3. When they click the button to complete sign up, the user will become a managed member of your Atlassian Organization. If Atlassian Access is set up, Trello will also redirect them to the IdP associated with your company.
  4. Once they've logged in, they'll be redirected into their Trello account.

If you have additional questions about domain allowlisting in your Atlassian Org, please connect with Atlassian Support or Trello Support.
