Multi-Factor Authentication

Installing the MFA App on a New iPhone

Did you use the county’s app for multi-factor authentication (MFA) and then found it didn’t work when you migrated to a new phone? Here are the directions to get it working again for you.

Note: County Apple redeem codes are tied to your Apple ID, so please do not attempt to install the AccessMCG MFA app on a device with a different Apple ID.

Launch the App Store on your new phone.

Tap the account profile, either a silhouette or your picture in a small circle at the top-right corner of the screen.

Tap Purchased to access a list of apps you have purchased/downloaded.

Scroll to the AccessMCG MFA app in the list and tap the download button to the right of the app name.

Wait for the device to finish downloading and installing the app.

Launch the AccessMCG MFA app on your device.

Going to ePortal (via Quicklinks) and click the My Account button. Log in thereafter and complete the activation.

Choosing Where (and Where Not) to Send Your MFA Code for Office and ePortal

When you go to log into ePortal or Office, are you getting a code for multi-factor authentication (MFA) in too many places? Do you prefer to change where it’s going now?

Go to ePortal (either by direct link or via Quicklinks).

Click the My Account button and log in as directed. (Key in the MFA code you receive.)

My Account Button



Find and click Select Multi-Factor Authentication Options link in the list.

Select MFA Options Link




Key in the MFA code that the system sends you.

Check or uncheck boxes to set your preferences as to where you would like to receive MFA codes from the county and click the Save MFA Options button.

Save MFA Options button



Log out of ePortal when you are finished.

Using a Token or Fob for Multi-Factor Authentication

Have you opted to use a token or fob for multi-factor authentication? Assuming you already have filled out the tech service request (TSR) and have been notified by your battalion chief that it is ready for you, here are the instructions for use.

Background: A key fob is a small device that is about two inches in length and an inch wide. The device generates a password, which you will use in place of a text to your cell phone or message to your e-mail account for multi-factor authentication in Montgomery County systems. Remember, this key fob is assigned to you and will not work for anyone else’s account. Likewise, secure it and do not lose it, which would defeat the purpose of needing a second login code to keep others out of your accounts.

MFA Key Fob






  • Log into ePortal or Office 365. You will be promoted for a code.
  • Press the white button on the left side of the key fob and note the six-digit code that appears.
  • Enter the code into your MFA screen to be granted access.

    (Note: The code will be good for about 30 seconds before a new code is generated and displayed on the screen.)
