Configuring multi-factor authentication in Office 365

Multi-factor authentication creates an additional level of security when accessing your Office 365 of Office 2016 applications. But it needs to be set up first…

Multi-factor authentication (MFA) is a security protocol that requires your to verify your identity in more than one way.  Typically this involves receiving a phone call or text message when attempting to access an online service.  The call or text will instruct you to enter a code to continue the log in process.

After multi-factor authentication has been enabled for your Office 365 account, you will need to configure the service.  Office 365 will automatically take you to the setup options when you attempt to log in.

Step 1. Choose the authentication method that works best for you.  Your options are:

  • Authentication phone – a text will be sent to you or you can receive a call.
  • Office phone – same as authentication phone, but only to your office number.
  • Mobile app – you download a mobile app that has revolving codes on it.  You enter the code when Office 365 prompts you.

In this example, we’ll use authentication phone.

Step 2.  Office 365 will send you a text with a code to confirm you are the expected owner of the account.  Enter the code to verify and continue.

Step 3.  The last step involves giving you an app password.  Please copy this code down somewhere.  You will need it later if you use Office 2016 apps on your computer like Outlook 2016 or Skype for Business.

That’s it!  Multi-factor authentication is now configured for your account.  Whenever you try to access Office 365, you will prompted to enter your password and then receive and enter a code texted to your phone.

If you ever receive a text but don’t remember logging in to Office 365, this might be an indication that someone is attempting to access your Office 365 account.  Please contact the help desk immediately so we can look in to the cause.
