Using Multi Factor Auth in Outlook 2013

› Outlook › Using Multi Factor Auth in Outlook 2013

Last reviewed on February 25, 2024     16 Comments

If your version of Outlook 2016 has all updates installed, you do not need to set a registry key to use MFA. It will work with Outlook.com, Office 365 business accounts, Gmail and third-party identity providers.

A user was griping about support for Multi Factor authentication (MFA) in Outlook Home version:

Multi Factor auth is enabled on my Office 365 account. I don't have problems using Outlook and MFA at work (with an Office 365 Enterprise license) but at home I need to use an app password in Outlook 2016 from my Home Premium subscription.

Not all programs support MFA at this time, so you may not be able to avoid using App passwords completely, but you don't need app passwords with Outlook 2013 or 2016. You can set a registry key on your home computer to enable MFA in Outlook.

If you need to create an app password, create a new at Create Office 365 App Password. Create App passwords in Outlook.com

These keys are needed to enable MFA in Outlook 2013

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\15.0\Common\Identity
DWORD:EnableADAL
Value: 1

DWORD: Version
Value:1

Outlook 2016 (not needed unless your Outlook does not have updates installed):

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\Identity
DWORD:EnableADAL
Value: 1

Do It For Me

If you don't want to edit the registry yourself, use one of these ready-to-use reg files. Note: you may need to right click on the link and choose Save target as or Save link as to save it to your hard drive. Double click on the reg file to run it.

There are other Enterprise features missing from Outlook Home, such as the archive mailbox and retention policies. Unfortunately, there isn't a registry key that will enable these features. You'll need to use Outlook on the web if you need to look at something in your archive mailbox or apply retention policies.

My employer organization have been using MS Cloud and MS Outlook Mail with SSO login for a few years. They recently introduced 2-step authentication, so my MS Outlook 2013 client (at home) stopped working. I added the (2013) registry key as you advised and it did **not** work.

Then I installed MS Outlook 2016 and added the (2016) registry key and it did work. Do you have any suggestions why your hack works with MS Outlook 2016 client and does not work with MS Outlook 2013 client for SSO 2-step authentication? Thanks.

You shouldn't need to the key for 2016 if you have all updates installed - it should now support it correctly

Add this key for 2013-
HKCU\SOFTWARE\Microsoft\Office\15.0\Common\Identity
DWORD: Version
Value:1

Nope, the above registry addition does not help with Office 2013. Could have my organization explicitly restricted old(er) outlook clients on the the MS server side?

They could. Microsoft no longer supports it as a client but did not block it.

Thank you so much - this was the 2nd last step!
I have been trying to use personal Outlook with my corporate Office-365 email account. It IS doable!

First, I had to remove bad account from Outlook (Previously, we had Exchange). Eventually I got Outlook to open, with no account assigned.

I added the regedit key from here. (It did not exist.)
I added a new account (name, email address) but no password).
It then prompted me to enter the code from the MFA Authenticator app on my phone.

Hurray! And thank you again!

Tried running the regedit and found the key did not exist. Added the key manually and value but Outlook is still asking for password. Create new APP password, no dice. What do you suggest?

This is with an Outlook.com or Office 365 Exchange account?

Which version and build of Outlook are you using? See File, Office Account for the information.

You shouldn't need the key for Outlook 2016 anymore, but may need it with Outlook 2013.
