Enable ADAL Authentication via Registry Editor

Updating your registry settings to enable the Active Directory Authentication Library (ADAL) can resolve sign-in issues caused by modern authentication requirements in SharePoint Online.

Because SharePoint Designer 2013 uses older authentication protocols by default, it may struggle to connect to modern SharePoint Online environments. Enabling ADAL forces the application to use modern authentication.

1
Open Registry Editor

Press the Windows Key + R to open the Run dialog, type 'regedit', and press Enter to launch the Registry Editor.

2
Navigate to the Identity Key

In the left pane, navigate to the following path: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\15.0\Common\Identity.

3
Create or Update EnableADAL

Right-click on an empty space in the right pane, select New > DWORD (32-bit) Value, and name it 'EnableADAL'. Double-click it and set the Value data to 1.

4
Create or Update Version

Similarly, right-click to create another New > DWORD (32-bit) Value named 'Version'. Double-click it and set the Value data to 1.

5
Restart and Test

Close the Registry Editor, restart your computer, and attempt to sign in to SharePoint Designer again.

Frequently Asked Questions

SharePoint Designer 2013 uses legacy authentication protocols by default. Modern SharePoint Online environments require modern authentication (ADAL), which must be manually enabled in the Windows Registry for older Office 15.0 clients.

Is SharePoint Designer 2013 still supported by Microsoft?

SharePoint Designer 2013 is no longer in mainstream support. Its extended support is primarily limited to compatibility with SharePoint Server 2016, and it may not support newer SharePoint Online features.

What is the recommended alternative to SharePoint Designer for workflows?

Microsoft strongly recommends migrating your legacy SharePoint site workflows to Power Automate, a modern, cloud-based tool designed for robust automation and collaboration.
