MS Edge IE Mode security settings

Hello,

I am prepping to remove Internet Explorer 11 from my organization devices and replace with IE mode. During testing I noticed that sites are blocked from allowing username/password in IE11 and MS Edge browsers but the pop-up window shows when launching the site within a Edge IEMode browser. HTTP Authentication is configured to 'negotiate' via GPO for both MS Edge and IE11.

My question is: does IE Mode allow users to bypass this security setting?

    Hi @Wahid Moore

    First, the group policy you set won't work in Edge IE mode and IE. The pop-up showing may be related with some settings in IE. You can also refer to this article for more information.

    Second, you can try the following things to see if it can fix the pop-up issue in IE/IE mode:

    • Modify the security settings in Internet Explorer
      1. Search Internet Options in the search bar on the desktop and open it.
      2. Click the Security tab.
      3. If your computer is connected to the Internet, click Internet, and then click Custom Level.
        If your computer is connected only to a local intranet, click Local Intranet, and then click Custom Level.
      4. In the Security Settings dialog box, make sure that Automatic logon with current username and password is enabled under User Authentication.
      5. Click OK two times.
    • Enable Integrated Windows Authentication in Internet Explorer
      1. Open Internet Options.
      2. Click the Advanced tab.
      3. Verify that the Enable Integrated Windows Authentication check box is selected.
      4. Click Apply, OK to save the setting if you change it.

    IEMode simply engages IE, and so to control IEMode once engaged, you set the relevant IE settings, just exactly the same as you would do for IE itself.

    If IE is configured to behave in a certain way, IEMode will honour those same settings.

    Hi @Wahid Moore

    If IE is no longer installed, you need to make sure Internet Explorer 11 is enabled in Windows Features so that you can use Edge IE mode.
    IE mode supports Internet Explorer settings and group policies that affect security zone settings and Protected Mode. I think you can still configure IE group policies. You can refer to this doc to see what IE mode supports.
