What is Azure Multi-Factor Authentication?
Two-step verification is a method of authentication that requires more than one verification method and adds a critical 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)
Azure Multi-Factor Authentication (MFA) is Microsoft’s two-step verification solution. Azure MFA helps safeguard access to data and applications while meeting user demand for a simple sign-in process. It delivers strong authentication via a range of verification methods, including phone call, text message, or mobile app verification.+
Why use Azure Multi-Factor Authentication?
Today, more than ever, people are increasingly connected. With smart phones, tablets, laptops, and PCs, people have several different options on how they are going to connect and stay connected at any time. People can access their accounts and applications from anywhere, which means that they can get more work done and serve their customers better.+

- 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 – We guarantee 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 Azure Multi-Factor Authentication works
The security of two-step verification lies in its layered approach. Compromising multiple verification methods presents a significant challenge for attackers. Even if an attacker manages to learn your password, it is useless without also having possession of the trusted device. Should you lose the device, the person who finds it can’t use it unless he or she also knows your password.+
Methods available for Multi-Factor Authentication
When a user signs in, an additional verification request is sent to the user. The following are a list of methods that can be used for this second verification.+
|Phone call||A call is placed to a user’s phone asking them to verify that they are signing. Press the # key to complete the verification process. This option is configurable and can be changed to a code that you specify.|
|Text message||A text message is sent to a user’s smart phone with a 6-digit code. Enter this code in to complete the verification process.|
|Mobile app notification||A verification request is sent to a user’s smart phone asking them complete the verification by selecting Verify from the mobile app. This occurs if app notification is the primary verification method. If they receive this notification when they are not signing in, they can report it as fraud.|
|Verification code with mobile app||The mobile app on a user’s device generates a verification code. This occurs if you selected a verification code as your primary verification method.|
For the mobile app verification methods, Azure Multi-Factor Authentication works with third-party authentication apps for smart phones. However, we recommend the Microsoft Authenticator app, which is available for Windows Phone, Android, and IOS.
