Microsoft Azure Multi-Factor Authentication (monthly subscription for 1 user)

Multi-Factor Authentication (MFA) is a method of authentication that requires the use of 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 MFA is a method of verifying who you are that requires the use of more than just a username and password. It provides a second layer of security to user sign-ins and transactions.

Azure MFA helps safeguard access to data and applications while meeting user demand for a simple sign-in process. It delivers strong authentication with a range of easy verification options - phone call, text message or mobile app notification - allowing users to choose the method they prefer.

Azure MFA is an easy to use, scalable and reliable solution that provides a second method of authentication so your users are always protected.

The security of multi-factor authentication lies in its layered approach. Comprising multiple authentication factors presents a significant challenge for attackers. Even if an attacker manages to learn the user's password, it is useless without also having possession of the trusted device. Should the user lose the device, the person who finds it will not be able to use it unless they also know the user's password.
