The miniOrange ADFS MFA connector helps you to enable Two Factor Authentication (2FA) for your users to protect the access to Microsoft Active Directory Federation Services (ADFS) by adding a second layer of authentication challenge to existing username and password of ADFS Deployment. This extra layer prevents the unauthorized person from accessing the resources even if cyber attackers get to know your credentials.

ADFS SSO Authentication Flow with miniOrange MFA Connector:

• A user attempts access to ADFS protected service with username / password.
• The username / password is verified against an existing first factor directory (i.e. Active Directory)
• Once the user's first level of authentication gets validated ADFS sends the confirmation to miniOrange Authentication Server.
• Now miniOrange Authentication Server asks for a 2-factor authentication challenge to the user.
• Here user submits the response/code which he receives on his hardware/phone.
• User response is checked at miniOrange’s Authentication Server side.
• On successful 2nd factor authentication the user is granted access to login.

Install miniOrange ADFS MFA Adapter

Use the command to Unregister the adapter:
Unregister-AdfsAuthenticationProvider -Name "miniOrangeADFSMFA"

Restart the adfs service using the following command:
