Configuring YubiKey authentication for Active Directory password resets and logins
YubiKey Authenticator is a hardware authentication device that is widely used as a multi-factor authentication (MFA) method. Authentication using this method involves plugging the YubiKey device into a user's machine or tapping it against the user's mobile device. A code is generated on the device and is automatically entered on the authentication screen and the user is authenticated into the service.
Since the code is generated and automatically entered in mere seconds, there is no chance of attackers figuring out the passcode and using it to breach the user's account.
Active Directory-based user actions like domain logins have for long been secured only by the rudimentary username and password. While the purpose of these credentials is to verify user identity, the advancement of technology has left them prone to breaches. Implementing an MFA method like YubiKey Authenticator in addition to the default username-password authentication during Active Directory domain logins can be extremely beneficial to an organization's domain network security. Another useful application is during self-service Active Directory password resets and account unlocks.
ADSelfService Plus, an Active Directory self-service password management and single sign-on solution, supports MFA using YubiKey Authenticator and 18 other methods. MFA is used by ADSelfService Plus to secure the following actions:
- Active Directory self-service password reset or account unlock actions via the ADSelfService portal, ADSelfService Plus mobile app, and native Windows/macOS/Linux login screen.
- Windows, macOS, and Linux logins.
