Single Sign-on

Access to Single Sign-On (SSO) is currently available as an add-on for users with a Pro level subscription.

If you would like to subscribe to Pro, you can do so in your subscription settings at Admin > Settings > Subscription and Billing.  

Getting started

What is single sign-on?

Single sign-on (SSO) is a protocol for authenticating an existing user to comment without registering for a global Disqus account. This assumes that you have an proprietary database of users already established.

What's SSO good for?

SSO is valuable for keeping existing users - It allows users in your own database to comment without forcing them to register with Disqus.

Can I use SSO on multiple sites?

Yes, but it is only possible to create one remote domain per user account, and we recommend using a single remote domain per site. If you require an additional remote domain, please create an additional user account for which we can enable SSO.
