Office 365 and Multi-factor Authentication

When it comes to protecting your accounts, multi-factor authentication (or two-step verification) should be standard across your organization. Multi-factor authentication is an easy-to-use, scalable, and reliable solution that provides a second method of authentication to protect your employees. Microsoft’s Azure Multi-Factor Authentication gives you peace of mind when it comes to securing employees tablets, laptops, PC’s, and smart phones when they are on-the-go, working remotely, or collaborating in the office.

Azure Multi-Factor Authentication benefits:

  • Easy to Use – Azure Multi-Factor Authentication is simple to set up and use. The extra protection that comes with Azure Multi-Factor Authentication allows users to manage their own devices. Best of all, in many instances it can be set up with just a few simple clicks.
  • Scalable – Azure Multi-Factor Authentication uses the power of the cloud and integrates with your on-premises AD and custom apps. This protection is even extended to your high-volume, mission-critical scenarios.
  • Always Protected – Azure Multi-Factor Authentication provides strong authentication using the highest industry standards.
  • Reliable – Microsoft guarantees 99.9% availability of Azure Multi-Factor Authentication. The service is considered unavailable when it is unable to receive or process verification requests for the two-step verification.

How Does Multi-Factor Authentication work?

Multi-factor authentication (MFA) is a method of authentication that requires the use of more than one verification method and adds a second layer of security to user sign-ins and transactions. It works by requiring any two or more of the following verification methods:

  • Something you know (typically a password)
  • Something you have (a trusted device that is not easily duplicated, like a phone)
  • Something you are (biometrics)

Multi-factor authentication in Office 365

Office 365 uses multi-factor authentication to help provide the extra security and is managed from the Office 365 admin center. Office 365 offers the following subset of Azure multi-factor authentication capabilities as a part of the subscription:

  • The ability to enable and enforce multi-factor authentication for end users
  • The use of a mobile app (online and one-time password [OTP]) as a second authentication factor
  • The use of a phone call as a second authentication factor
  • The use of a Short Message Service (SMS) message as a second authentication factor
  • Application passwords for non-browser clients (for example, Microsoft Skype for Business)

How can you start using MFA?

MFA is already included in most Office365 licenses. OnPar can easily activate this service per your request.
