Google Authenticator User Guide

Problem

You need to set up two-factor authentication (2FA) with the Google Authenticator app to change specific settings in the Merchant Management System (MMS), or move your codes to a new phone or recover access after losing one.

Resolution

Set up Google Authenticator

1. Download the Google Authenticator app

   • Have the mobile device you want to use at hand.
   • Install the Google Authenticator app on your device from your device's app store.
   • Make sure the time on your device is set correctly.

2. Log into the MMS

   • Open the MMS and log in with your user credentials (Username and Password), then click Login.

3. Link your device with your MMS account

   • Open the Google Authenticator app on your device and select + in the top right.
   • Select Scan barcode and point your mobile device at the PC screen to scan the QR code shown on the MMS Two-Factor Authentication (2FA) – Authenticator App Setup screen.

4. Finish the set-up

   • Your smartphone will now generate a six-digit number. Enter it into the Authentication Code field on the MMS, along with your current MMS password.
   • Download and safely store your backup codes.

Transfer your codes to a new device (if applicable)

1. Prepare both phones

   • You need your old phone with the Google Authenticator codes, the latest version of the Google Authenticator app installed on your old phone, and your new phone.
   • On your new phone, install the Google Authenticator app, tap Get Started, then at the bottom tap Import existing accounts?

2. Export from the old phone

   • In the Authenticator app on your old phone, tap More > Transfer accounts > Export accounts.
   • Select which accounts you want to transfer to your new phone, then tap Next. If you transfer multiple accounts, your old phone may create more than one QR code.

3. Scan on the new phone

   • On your new phone, tap Scan QR code.
   • After you scan your QR codes, you get a confirmation that your Google Authenticator accounts have been transferred.
   • If your camera cannot scan the QR code, there may be too much information in it. Try exporting again with fewer accounts.

If your phone is lost or stolen

1. Use backup options

   • If you have lost access to your primary phone, you can verify it is you with:
     • another phone signed into your Google Account;
     • another phone number you have added in the 2-Step Verification section of your Google Account;
     • a backup code you previously saved;
     • a security key you have added in the 2-Step Verification section of your Google Account.

2. Sign in from a trusted device

   • If you previously signed in from a device and ticked Don't ask again on this computer, you might be able to sign in from that device without a second verification step. After you sign into your Google Account, you can manage your verification methods.

3. Get a new phone from your carrier

   • If you lose your phone, you can ask your carrier to transfer your phone number to a new phone or SIM card.

4. Recover your account

   • If you cannot sign in, follow the account recovery steps. If you are having trouble, try the tips for completing account recovery.

Notes

• Logging in using 2FA is required to change specific settings within the MMS.
• Google Authenticator (or another app that creates one-time verification codes) works even when you do not have an internet connection or mobile service. Once you have received the code, enter it on the sign-in screen to confirm it is you.
• You can use other authenticator applications instead, such as Authy or LastPass Authenticator.
• This is a one-time registration process, and only one 2FA authenticator can be used per user account.
