You’ll be prompted to set up MFA when you first sign in or when your MFA is reset. MFA adds an extra layer of security by requiring a code or push notification from your phone in addition to your password.

Step 1 – Download the Auth0 Guardian App

Before continuing, install the Auth0 Guardian app on your mobile device:

Android (Google Play):

iOS (App Store):

Once installed, open the app.

Step 2 – Begin MFA Setup in DAT One

  1. On your computer or mobile browser, log in to DAT One.
  2. When prompted, you’ll see a screen asking you to set up your authenticator app.
  3. The screen will display a QR code.

You can link your Guardian app using Option A or Option B below.

Option A – Use QR Code

  1. In the Auth0 Guardian app, tap “➕”, and choose Scan code.
  2. Grant camera access if prompted. Point your phone’s camera at the QR code displayed in DAT One.
  3. The app will auto-add your account and begin generating one-time codes.

Option B – Enter Setup Key Manually

If scanning the QR code isn’t possible (e.g. your setup screen and phone are on the same device):

  1. Tap Trouble Scanning?
  2. Click Copy Code.
  3. In the Auth0 Guardian app, tap “➕”, and choose Scan code.
  4. Enter an Account name (e.g. “DAT One”).
  5. Paste or type the setup key shown on your DAT One screen.
  6. Tap Submit.
  7. The app will begin generating one-time codes (refreshing every 30 seconds).

Step 3 – Verify Your MFA Setup

  1. Return to the DAT One login screen in your portal. Enter the current 6-digit code from the Guardian app. Click Continue.
  2.  You’ll receive a recovery code. This code serves as a backup in case you lose access to your primary MFA method. It allows you to log in without your usual MFA factor but does not reset your authentication settings. Each time you use a recovery code, a new one is generated for future use.
    Click Copy Code, put a checkmarkm next to I have safely recorded this code, and click CONTINUE.

Step 4 – Logging In After Setup

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

  1. Enter your email and password. You’ll be prompted for MFA.
  2. Open the Auth0 Guardian app. Find the DAT One entry and note the 6-digit code.
  3. Enter that code in DAT One, and click CONTINUE.

Note: Put a checkmark next to Remember this device for 30 days for faster login.
