With an annual Enterprise license or the EDU Institution license, you are able to use single sign-on (SSO) authentication in order to control access to your Slido organization and to your events.

In this article:

There are two types of SSO protection that you can set up in Slido:

  • Participant SSO manages the participants' access. Use Google SSO or SAML based SSO authentication to make sure that only people from your company or specific department can join your internal meetings via Slido.
  • Member SSO manages the admin access which allows the members to create and manage Slido events. Only SAML SSO is supported.

Both SSO types are available only in our Enterprise and Institution plans. Participant SSO is also available in our Premium plan. This article will focus on Member SSO.


Member SSO


SAML-based single sign-on (SSO) gives Admins, Users, and Guests within a Slido organization access to Slido through their Identity Provider (IdP), for example, OktaOneLoginMicrosoft Azure, or Auth0, and others.


Member provisioning for selected IdPs is also available. It's possible to leverage our implementation of the SCIM protocol in case the IdP adheres to SCIM standards.


Member SSO can only be set up by the owner of the Slido organization. 

Steps to set up member SSO:

  • Upload your Identity Provider’s SAML metadata XML file to Slido
  • Test the configuration
  • Enable SSO
  • Enforce your members to log in via SSO
  • Allow Guests to log in without SAML SSO
  • Set up Member provisioning in selected Identity Providers


Upload your IdP's SAML metadata XML file to Slido


To get started, you need to set up your Identity Provider and acquire its SAML metadata XML file. Once you have it, you can upload it to your Slido organization.

  1. Open Organization settings
  2. Select Member SAML SSO
  3. Click Browse files to upload your IdP's SAML metadata XML file

Once uploaded, our system validates the XML file.

Upload Metadata to Slido for Member SSO

If the file is correct, you will see the Entity ID of your IdP updated. You may then continue with the setup.

Test the configuration


Before enabling the configuration, you first have to test it by clicking Test SAML Login.


This opens a new window redirecting you to your Identity Provider in order to validate that the integration setup is correct on both sides.


Successful test
If the integration is correctly set up and the test is successfully completed you will see a message saying Test successfully completed. Click Got it to go back to your Organization settings to continue with the setup.

Unsuccessful test
If the integration test fails you will see a message saying Test failed. Click Back to to go your Organization settings to fix the issue.

If the test fails, please double-check the uploaded XML metadata file. Also make sure that the person setting up the authentication in Slido is assigned to the associated SAML SSO application on the IdP side.


Enable SSO

After a successful test, you can enable the integration by clicking the Enable SSO button.



How it works for your members:
Once Member SSO is enabled, your members will be able to log in to Slido using SSO.

The member's other login options (such as password or Google login) will still remain available as well. The screenshot below shows the experience of a member who has the option to log in using either password or SAML SSO integration.


Once the user chooses to Log in with SSO, they will automatically be redirected to your Identity Provider.


Enforce your members to log in via SSO

When Member SAML SSO is enabled, you may choose to enforce it by clicking the Enforce SSO button. Enforced SSO means that it is mandatory for members to log in using your Identity Provider. This helps to fully secure your organization account.


How it works for your members:
If the SAML SSO is enforced, any member trying to log in will have to go through your IdP's authentication. The members will no longer have the option to log in with with Slido password or Google SSO. Instead, they will be redirected to your IdP.


Once you enforce SAML SSO, the members who are logged in at that moment will have to re-login to their Slido account.


Allow Guests to log in without SAML SSO

By default, when SSO is set up for the organization, the members can only invite other existing members to their events as guests. Sometimes, it might be useful to invite guests who are not from your company.


To allow inviting guests who are not a part of your Slido organization:

  1. Open Organization Settings - Member SAML/SSO
  2. Tick the Exclude guests option

The invited guests who are not part of your organization will use a password or Google account to log in to Slido.



Set up Member provisioning in selected Identity Providers

You can set up SAML SSO and provisioning for your Slido organization in the following IdP's, or any other that complies with SCIM standards:

  • Okta
  • OneLogin
  • Microsoft Azure
  • Auth0

    Useful information and FAQ:

  • Does Slido SSO authentication work from the service provider side, IdP, or both?
    Slido supports both SSO authentication flows.
  • How do I renew the SSO certificate?
    To renew your SSO certificate in Slido you will first need to disable member SSO in Organization settings. This will log you out so you need to log back in, open Organization settings and select Re-upload which you can find next to Metadata. Now upload your new .xml file, click Test SAML Login and if the test is successful, enable SSO again.
    Take a look at our video tutorial for renewing the SSO certificate
  • Can we use the same SAML XML file for both - participant and member SSO?
    Yes, this is possible. Be careful with using the single file setup with user provisioning though - the participants don't create accounts the same way as Slido organization members. User provisioning won't work correctly if you mark the participants and the members for provisioning the same way. A 2-app setup on the IdP side is recommended. Please contact us at if you need any help with your user provisioning setup.
  • Can I test the member SSO before saving the settings to make sure it's working?
    There is no testing environment for the member SSO setup at the moment, but there is a test as a part of the setup process. If the test passes it means the integration is working well and member SSO can be enforced for your Slido organization. That should be sufficient to validate your setup before it's applied to your Slido organization.
