Client advisory: Two-factor authentication guidance

Two-factor authentication (2FA), also known as multi-factor authentication (MFA), is an extra layer of security used to verify the identity of the person trying to gain access to an account. This document provides guidance on how to implement 2FA in several popular applications.

An overwhelming number of username and password combinations are readily available on the dark web and can be used by cybercriminals to gain access to your accounts. 2FA makes it much more difficult for them to gain access even if they have a legitimate password to hand. When 2FA is switched on, you’ll have to provide a second piece of information in order to access your account, which typically comes in the form of a code through a text message or authentication app, with the latter considered the most secure.

Some services will have 2FA switched on by default, but many do not. The following explains how to turn on 2FA in some popular business applications.

Microsoft Office 365

  1. Sign in to your admin center
  2. Select Users and Active users
  3. In the Active users section, click on Multi-factor authentication
  4. On the Multi-factor authentication page, select a user to enable this for one user or you can perform a bulk update by clicking update in bulk
  5. Click on Enable under quick steps
  6. In the pop-up window, click on enable multi-factor authentication

G Suite

  1. Sign in to your Google Admin console
  2. From the Admin console Home page, navigate to Security, then Basic settings
    1.  You may have to click More controls at the bottom
  3. Under Two-step verification, check Allow users to turn on 2-step verification
  4. Click Save


Individual users must then follow these steps:
