Why do I need the Authenticator App? Microsoft Authenticator is a security app used for two-factor authentication. This app is mandated by WaTech in order to use the Outlook App on your mobile device.

Before continuing, you will need to do the following:

  • Download the Microsoft Authenticator App from the App store on your personal mobile device. 

  • Set up your DES user account for multi-factor-authentication. This is a task that is to be done before you migrate to Office 365. If you have not set up MFA or you aren't sure, click Here.

After completing the two bullet items, you can continue on to the the steps below.

FROM A COMPUTER/TABLET or OTHER PHONE (after MFA has been completed):

  1. To start the process of setting up the Authenticator app, you will be taken to a familiar page. This is the page you used while you were setting up MFA. Click here to start setting up your DES account with the Authenticator App. 

  2. You will be taken to a Microsoft Sign in page. You will need to enter your state email address and click Next.


  3. You will be redirected to the State of Washington page where you need to enter your email address and password (the password you use to log on to your work account).


  4. Now you need to enter a code that should of been texted to your mobile device. This is part of the multi-factor authentication you previously set up. Enter the code in the Verification code box and click Sign in.


  5. When asked if you want to Stay signed in, check the box that says Don't show this again and click on Yes to continue.


  6. Now you see the Additional Security Verification page. Check the box next to Authenticator app or Token and click Set up Authenticator App.
