Integrated Windows authentication in Microsoft Edge

Question

I am trying to implement Integrated Windows authentication on Edge, but it always prompts me for credentials, whereas Integrated Windows authentication is working for IE, Chrome and Firefox. I have tried adding the site to local intranet sites in security options and enabled automatic login but no luck on edge browser.

Does Edge support Integrated Windows authentication?

I have tried adding the site to local intranet sites in security options and enabled automatic login as well login with current username and password.

Answer 1

Which version of Microsoft Edge version are you using? Please check the following configuration to Enable Integrated Windows Authentication:

1. Open Internet Explorer and select "Tools" dropdown.
2. Select the "Advanced" tab.
3. Scroll down to the "Security" section until you see "Enable Integrated Windows Authentication". Select the box next to this field to enable.
4. Select the "Security" tab.
5. Select "Local Intranet" and select the "Custom Level" or "Advanced" button.
6. Scroll down to "User Authentication" > "Logon".
7. Checked the "Automatic logon with current user name and password" option.
8. In the "Security" tab, select "Local Intranet" option and click the "Sites" button.
9. Click the "Advanced" button, then, add your website to the zone.
10. Close the window and apply the configuration.

If still not working, I suggest you could feedback your issue to Microsoft Edge platform forum, like this thread.

It may be because of AuthServerAllowlist. You can check your policies at edge://policy/.

Specifies which servers to enable for integrated authentication. Integrated authentication is only enabled when Microsoft Edge receives an authentication challenge from a proxy or from a server in this list.

[...]

If you don't configure this policy, Microsoft Edge tries to detect if a server is on the intranet - only then will it respond to IWA requests. If the server is on the internet, IWA requests from it are ignored by Microsoft Edge.

As the documentation states; if your server/site isn't included in the AuthServerAllowlist and Edge can't identify your site as an intranet site Edge won't use Integrated Windows Authentication.
