Hi @Joshua Wright
Teams tag is mainly focused on the general issue of Microsoft Teams troubleshooting. According to your description, your question is related to Microsoft Authenticator, which is not in our support scope. The following suggestion is just for your reference:
Ensure that you have the latest version of the Microsoft Authenticator app installed on your phone. You can download it from the App Store (iOS) or Google Play Store (Android).
Open the app and add your account by selecting the "+" or "Add account" button. You'll typically need to scan a QR code or enter a secret key provided by the service you're trying to authenticate with (e.g., your data gateway).
Once your account is added, the Microsoft Authenticator app will automatically generate a six-digit verification code that changes every 30 seconds or so.
When prompted for a code during the authentication process (such as when using the data gateway), simply open the Microsoft Authenticator app and check the current six-digit code displayed for your account.
