Enabling Modern Authentication in Office 2013

To enable Modern Authentication for Office 365, we need to add a couple of registry keys.

Create the following registry keys:

Registry Key	Type	Value
HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common\Identity\EnableADAL	REG_DWORD	1
HKCU\SOFTWARE\Microsoft\Office\15.0\Common\Identity\Version	REG_DWORD	1

Once you’ve created the registry keys, give your machine a reboot.

When you next open an Office 2013 application you will need to sign out and sign back in again for the change to come in

Here is a script to add the registry keys for you:

reg add HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common\Identity /v EnableADAL /d 1 /t REG_DWORD
reg add HKCU\SOFTWARE\Microsoft\Office\15.0\Common\Identity\ /v Version /d 1 /t REG_DWORD

If you want to remove Modern Authentication then switch the EnableADAL value to 0 or delete the registry key.

reg delete HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common\Identity /v EnableADAL
