How to Enable or Disable Sign-in to Microsoft Edge using non-Microsoft accounts in Windows 11

Signing in to Microsoft Edge using non-Microsoft accounts on Windows 11 controls whether you can link external services like Google or Apple to your browser profile. Starting with Microsoft Edge version 150, this built-in browser setting lets you decide if third-party login buttons appear on your sign-in screen.

Blocking this option hides external login buttons entirely, keeping your browser profiles strictly tied to standard Microsoft accounts. You can easily turn this setting on or off to manage how your browser handles different login credentials.

Here’s How:

Disable Sign-in to Microsoft Edge using non-Microsoft accounts for All Users

Blocking external account access across an entire PC requires a modification to the Windows Registry (a centralized database for system settings). This change applies globally to every profile on the machine.

1. Click the Start button.
2. Type regedit and press Enter. This opens the Registry Editor. You might see a User Account Control prompt; click Yes. (Requires Admin Privileges)
3. In the Registry Editor, go to the following location:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge

Missing registry keys require manual creation. Right-click the ‘Microsoft’ folder, select ‘New’, choose ‘Key’, and name the folder Edge.

4. Right-click on 🖱️ the Edge key.
5. Select New, then DWORD (32-bit) Value.
6. Name the new value NonMicrosoftAccountSignInEnabled
7. Double-click on NonMicrosoftAccountSignInEnabled.
8. In the Value data box, type 0 and click OK.

Name the new value NonMicrosoftAccountSignInEnabled. Double-click the new entry, type 0 in the Value data box, and click OK. Restricting this setting removes external sign-in options while preserving standard Microsoft account access for all local Windows 11 users.

3. In the Registry Editor, go to the following location:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge
