Single Sign-On SharePoint Online

Question

Is it possible to place a shortcut (link, button, or other component) within a SharePoint Online page that redirects to an external site (a provider's site) and, in doing so, use the SSO mechanism to automatically log in, without requiring a username and password again?

Hi @Johana Guevara , 

Good day! Welcome to Q&A forum.

Yes, it is possible to place a shortcut within a SharePoint Online page that redirects to an external site and use the SSO mechanism to automatically log in. Here are the general steps and related considerations:

Prerequisites

• Your organization needs to have a Microsoft Entra ID (Azure Active Directory) account1.
• The external site's provider should support SSO and have a trust relationship established with your organization's Microsoft Entra ID.

Configuration Steps

• Register the application in Microsoft Entra ID: Log in to the Azure portal, go to "App Registrations", and click "New Registration". Enter a name for the registration, select the supported account types, and leave the redirect URI section blank for now. After registration, go to the "Manifest" and confirm that the accessTokenAcceptedVersion is set to 2. Then, go to "Authentication", click "Add Platform", select "Web", add the redirect URI (the URL of the SharePoint Online page where the shortcut will be placed), and check the "ID token" and "Access token" checkboxes in the implicit grant section1.
• Configure SSO in the external site's provider: The specific steps vary depending on the provider. Generally, you need to enter the relevant information of the application registered in Microsoft Entra ID, such as the client ID and tenant ID, into the provider's SSO configuration page. At the same time, the provider may also need to provide some callback URLs or endpoints and configure them in Microsoft Entra ID to establish a trust relationship.
• Add a shortcut to the SharePoint Online page

After the above steps are completed, when users access the SharePoint Online page and click the shortcut to the external site, they should be able to automatically log in to the external site through the SSO mechanism without entering their usernames and passwords again, provided that the user has already logged in to the SharePoint Online page and has the corresponding permissions.
