Microsoft Teams + Edge Chromium? Here’s how to get rid of those annoying additional logins.

Are these login boxes familiar? Keep on reading!

They often show up if you are using Edge Chromium as your browser and, from the Microsoft Teams client, open a file in “Files”or if you try to open the Team SharePoint site. (and also sometimes when You open a tab that shows a file).

The problem occurs in environments with Azure Active Directory Seamless Single Sign-On enabled. Usually the URL below is added to the “Local Intranet” security zone, but Edge Chromium handles this differently.

This has been an issue for some time now, until a few days ago when my innovative and good colleague Håvard Øverås, who is a high ranked problem solver, came up with the solution. Since it can be useful to many of you and I want to share it with you here.

Below you will find 3 different variants that you can choose from to solve it in the way that is best for you or your organization

The Solution(s)


1. Manual configuration on one Computer

Open RegEdit, and go to HKEY_CURRENT_USER\SOFTWARE\Microsoft\Edge
Then add “AuthServerAllowlist”=””.

2. Group Policy

(Download the Edge policy template here: and add it to the central store.)

Open this policy in a GPO:

User Configuration > Administrative Templates > Microsoft Edge > HTTP authentication > Configure list of allowed authentication servers.



3. Intune

Create a Device Configuration Policy and choose:

  • Platform: Windows 10 or later
  • Profile type: Administrative Templates
  • Category type: Edge version 77 and later
  • Setting Name: Configure list of allowed authentication servers
  • Enable the setting and add



Many thanks to Håvard for this! You made my day (once again) and I think this will be received with gratitude by many others as well.
