Multi-Factor Authentication (MFA) setup with Microsoft Authenticator

3 minute to read

When you sign up or your MFA is reset, you will be prompted to set up multi-factor authentication (MFA) in DAT One Web or DAT One Mobile.

MFA adds an extra layer of protection by requiring a verification code from your phone in addition to your password.

Step 1 – Download the Microsoft Authenticator App

Before continuing, install the Microsoft Authenticator app on your phone.

Android (Google Play):

iOS (App Store):

Step 2 – Begin MFA Setup in DAT One

  1. Log in to DAT One from your computer or mobile browser.

  2. When prompted, choose to set up your authenticator app.

  3. A QR code will appear on the screen.

You can connect Microsoft Authenticator using either option below.

Option A – Scan the QR Code

  1. Open the Microsoft Authenticator app on your phone.

  2. Tap +(Add account).

  3. Select Work or school account or Other account.

  4. Choose Scan a QR code.

  5. Allow camera access and scan the QR code displayed in DAT One.

  6. A new entry labeled DAT Solutions will appear showing a 6-digit code.

Option B – Enter the Setup Key Manually

If you cannot scan the QR code (for example, when setting up on the same phone):

  1. Select Trouble scanning? in DAT One.

  2. Copy the setup key shown on the screen.

  3. Open Microsoft Authenticator and tap +.

  4. Choose Other account → Enter code manually.

  5. Enter DAT One as the account name.

  6. Paste the setup key.

  7. Save to generate a 6-digit verification code.

  8. Enter the code in DAT One and click CONTINUE.

You will receive a recovery code. This code allows you to log in if you lose access to your authenticator app. Store it in a safe place. Each time you use a recovery code, a new one will be generated.

Step 3 – Logging In After Setup

After MFA is configured, each time you log in to DAT One Web or DAT One Mobile:

  1. Enter your email and password.

  2. Open the Microsoft Authenticator app.

  3. Locate the DAT One entry and note the 6-digit code.

  4. Enter the code when prompted and click CONTINUE.
