I would love to be able to fully deploy Azure MFA to all server authentication requests. I just recently rolled out Azure MFA to my remote access VPNs. It would be great if I include more services like server authentication. Currently I am using RSA MFA when logging in to servers, where I am prompted for a passcode after entering my AD credentials. I would love to use Azure MFA in a similar manner, where I can approve the login request through the Authenticator app, or use the passcode generated in the app.
