Overview
Multi-factor authentication (MFA) is a critical step to protecting your data. In this guide, you will set up MFA through a mobile app on your phone. After setting it up, whenever your account is signed into from a device that is not connected to your work domain, the sign-in screen will prompt you to confirm that it's actually you trying to sign in. You'll need to approve the prompt on your phone in order to complete the sign-in attempt.
If you run into any issues along the way, please see this MFA Troubleshooting Guide.
Note: If you have recently received a new phone, please contact the Help Desk to reset your MFA.

Note: Some of the steps may be slightly different depending on your organization's policies, but generally the process is as follows below.
Part 1: On your computer
- Open a browser and navigate to https://aka.ms/mfasetup
- Follow the latest available instructions which will be provided on-screen.
I lost my phone
It is critical that you report any lost or stolen phones to the CTD Help Desk immediately so we can help prevent access to your account by third parties.
** If you reside full time outside of the United States and need assistance outside of CTD's Help Desk hours (6am - 5pm Pacific), please contact your local MFA reset admin for assistance.
I have a new phone
If you are replacing your old phone, don't toss it or factory reset it right away. Instead, set up MFA on your new phone first.
- Open a browser and navigate to https://aka.ms/mfasetup
- Select 'Add sign-in method' and choose 'Authenticator App' and follow the on-screen instructions.
