And this is the part where DUO comes around. But today end of the year 2022, almost Christmas, we all know that not using MFA could be deadly from a security perspective. These companies had a Break glass protocol in place that made sure that in case of an emergency Administrators were always able to logon to the environment to disable the MFA services. But there were some companies who were able to work. Even administrators were not able to log in to disable the multifactor so company operations could work around the Microsoft outage. A lot of companies were doomed and were not able to log on to the Microsoft 365 environment. But did you know it can also help you make your environment more secure? In November 2018 Microsoft had a major outage on their Multi-factor services. In most cases, companies prefer using DUO as a multifactor because of the easy adoption for end users. In this blog post, I will guide you through the process of the third solution DUO multifactor authentication, and also why you should use this instead of Azure Multifactor authentication. Do you prefer the old-school implementation through the legacy portal or do you enforce it with conditional access rules. Using Duo makes 2FA deployment in Windows a manageable task due to its integration with so many applications and platforms.Most of you know how to setup Microsoft Authenticator and most of you probably also know how to use it. The “Passcode” option is for when an authenticator app like Duo provides a temporary passcode for the user to enter.Īlthough there have been increases in hacking two-factor authentication, enabling this in an enterprise still provides a great layer of protection in the security scheme. The “Call Me” option means that a number will be called by Duo, and the user will need to accept the call and press a key. I log-in as usual to my workstation (I could also use RDP), but after I enter my username I am prompted with the following message:ĭepending on the Duo policies configured, a user can send a Duo push, call or enter a passcode in order to perform the secondary authentication for two-factor authentication.Ī Duo push, means that a prompt will be send to accept on a mobile device configured for Duo, such as an iPhone. Now it's time to test out Duo on a Windows machine.
