Multi-factor authentication (MFA) is an authentication method that requires the user to provide two or more verification factors to gain access to an online account, application, or VPN. When accessing accounts or apps, users provide additional identity verification such as scanning a finger-print or entering a code received by your phone.
The main benefit of MFA is that it will enhance your organisations security by requiring your users to identify themselves by more than a username and password. One of the biggest weaknesses of traditional user ID and password logins is that passwords can be easily compromised, potentially costing organizations millions of dollars. Brute-force attacks are also a real threat, as cyber criminals can use automated password cracking tools to guess various combinations of usernames and passwords until they find the right sequence. Enforcing the use of MFA means increased confidence that your organization will stay safe from cyber criminals. Accounts with MFA enabled are 99.9% less likely to be compromised
One of the most common MFA factors that can be used are one-time passwords. An SMS message can be sent to your mobile phone with a six-digit code to ask for a second layer of authentication whilst logging in. Microsoft have a dedicated Authenticator App which sends a push notification to your phone for approval of your login attempts.
Other factors that can also be used are answers to personal security questions or fingerprint or facial recognition.
If you choose to use the Microsoft Authenticator App, you won’t have to enter this second code every time you log into your device. Generally, it will only need to be used the first time you sign into an app or device or the first time you sign in after changing your password.
