Overview of MFA for Remote Desktop Web Access
Rublon MFA for RD Web connector adds Two-Factor Authentication (2FA) to Microsoft Remote Desktop Web Access logons. When a user attempts to log in to RD Web Access with Rublon 2FA enabled, they have to first provide their credentials and then select an Authentication Method from Rublon Prompt. Depending on the chosen method of authentication, the second factor of authentication looks slightly different, but in the end, if a user confirms their identity, they are logged in to RD Web Access. Users who do not complete the Two-Factor Authentication process are denied access.
Rublon MFA for Remote Desktop Web connector also adds Two-Factor Authentication (2FA) to RD Web Client and RD Web Feed logons. Mobile Push and Email Link authentication methods can be used to authenticate to these products.
Note that RD Web Access is used only to download data about remote resources (RDP files). To secure the connection to a remote resource, use Rublon MFA for RD Gateway or Rublon MFA for Windows Logon and RDP.
