Circle supports Single Sign-On (SSO), and you can now integrate Circle with Memberful, making it a seamless experience for your Memberful members to log in to your community! These members won't have to sign up or log in with their Circle account — instead, they'll use Memberful credentials and access Circle from your log in page.

Memberful SSO is available for Professional and Enterprise plans. Please reach out to us at support@circle.so if you're interested in getting this enabled.

✅  Step 1: Set up Circle integration in Memberful

First, navigate to Memberful Settings → Integrate → Custom Apps → Add a New Custom Application.


Name your integration, and then locate your Circle Callback URL by navigating back to Circle (Circle Community Settings → Single Sign-On).

If you plan to use a custom domain, set that up first as this will change your Callback URL.

🚨 We recommend keeping the "Allow members with a Circle account to sign in" toggle enabled to avoid getting locked out of your account while setting up your SSO integration. In the case this happens, you can easily sign in again with your Circle credentials.
Once you click "Create" in Memberful you will be presented with your custom ID's.

✅  Step 2: Copy over Memberful SSO information to Circle

Navigate to back to Circle Settings → Single Sign-On, and select "Memberful" as the OAuth provider.

Type in your provider name, then paste in your Client ID along with the Secret Key provided by Memberful and click "Save".


✅  Step 3: Enable SSO with Memberful

Once you've saved your settings, toggle "Enable SSO" to ON within Circle.
  • Allow members with a Circle account to sign in: If you have members that have already registered their email with Circle, they can still sign in with those credentials using a separate sign-in button.

💡 What happens to Circle member accounts?
If this is toggled ON, Circle members can continue to login using the "Sign in with Circle" button. We will create accounts for Memberful members automatically on our backend if the email doesn't exist within Circle.

If this is toggled OFF, members with Circle accounts will no longer be able to sign in with those credentials unless the email of their Circle account matches the email of their Memberful account, in which case we'll link the two automatically going forward.

💡 What happens to my admin account?
If the email you use to log in to Memberful is different from Circle, we recommend toggling this ON to ensure you don't get locked out of your admin account. Once you grant admin rights to both accounts you can always toggle this off later.

If this is toggled OFF, you will only be able to log in under your email that is registered within Memberful.
  • Allow members to sign up via a custom URL: After enabling SSO, members won't be able to sign up via Circle. However, you can keep the sign up button visible and point it to a custom URL.

🏁  If the setup was successful, you will now see the Login via Memberful Single Sign-On option when trying to sign in under your community!
