Be more secure with Microsoft’s new Multi-Factor Authentication!

From 1st August 2019, Microsoft’s more comprehensive three-way Multi-Factor Authentication (MFA) will not only be turned on for all Office 365 Users, but also, free to implement and use!​

That’s great! …but what is Multi-Factor Authentication (MFA)?

Essentially MFA is a security mechanism which requires individuals to be authenticated through more than one required security and validation procedure. It works by requiring two or more of the following authentication methods: ​

  1. Something you know… (typically a password)​
  2. Something you have… (a trusted device that is not easily duplicated, like a phone) ​
  3. Something you are… (biometrics)​

Unsure about what all of this jargon means?

What will an End User need to do?​

​Your End Users will need to download the Microsoft app from their relevant App Store (Google Play or Apple App Store (best)).​

The Microsoft Authenticator app will allow the End User to sign-in to their accounts using two-factor verification. Two-factor verification is an additional security step that helps protect an End Users account by making it harder for other people to break in.​

​Once the End User has downloaded and installed the app on their mobile device, they will need to authenticate via the app each time they log into O365.​

​How will verification work within the App?​

​Microsoft Authenticator verification will work in the following ways:​

  1. Notification – End User types username and password into the device they are logging into for work account or their personal Microsoft account, and then the Microsoft Authenticator app sends a notification asking the End User to Approve sign-in. Choose Approve if they recognize the sign-in attempt. Otherwise, choose Deny. If the End User chooses Deny, they can also mark the request as fraudulent.​
  2. Verification code – End User types username and password into the device they are you’re logging into for work or personal Microsoft account, and then copy the associated verification code from the Accounts screen of the Microsoft Authenticator app. The verification code is also known as one-time passcode (OTP) authentication.​
  3. Passwordless sign-in – End User types username into the device they are logging into for work or personal Microsoft account, and then use their mobile device to verify it’s themselves by using fingerprint, face, or PIN.​
