What is the “My Apps Secure Sign-in Experience” Extension for Edge
In order to leverage Single sign-on to your “Password Based” Azure AD applications, your Windows users will need to install a browser extension.
The “My Apps Secure Sign-in Experience” Browser Extension will handle the authentication to applications using the credentials that are stored in a Password Vault in Azure. I have another post coming soon on how to enable SSO for password based applications *
Your users will be prompted to download the extension when they select an application that is configured for “Password based” SSO. Alternatively, as an admin, you can deploy the extension to their computer – silently. Much better right?
*The extension also allows you to access internal company URLs, from an internet device, for apps published using the Application Proxy.

Deploy the Extension with Intune
Before we can publish any extension to Edge using Intune, we must first get the Application ID and Update URL for the extension.
1 . Navigate to https://microsoftedge.microsoft.com/addons/category/EdgeExtensionsEditorsPick

2 . Search for My Apps Secure Sign-in Extension

3 . Grab the App ID from the URL – gaaceiggkkiffbfdpmfapegoiohkiipl

The ADMX value will be gaaceiggkkiffbfdpmfapegoiohkiipl;https://edge.microsoft.com/extensionwebstorebase/v1/crx

14 . Click Next
15 . Click Next
16 . Click the Assign to drop down box and choose All Devices *

17 . Click Next
18 . Review the profile and click Create

19 . Review the deployment status of the new Configuration Profile

20 . The devices will automatically install the extension. You can view if this was successful by viewing the extensions within Edge on the client device
