In GoPilot, select ID Providers from left menu, then click on ‘New ID Provider’ button on the right. After this select which Single Sign on provider you would like to setup.

For example, let's add Microsoft as the Identity provider:
Fill in values from Azure AD console

Then click ‘Add Provider’ button.

For Google and others, follow the same procedure and fill in the appropriate values gathered from the Identity Provider.

Once an Identity Provider is added, you will be brought back to "All Providers"  screen
