Two-factor authentication for Citrix Receiver for Windows

I am glad you brought this up so that I can share the good news! It's possible to do now with 11.6.0 HF4!

It will get easier when v12.0 is launched in the summer, but until then you can try this when you upgrade to 11.6.0 HF4:

Create a new Variable Assignment action in front of your Logon Page. On the left hand side, specify this variable name: session.citrix.client_auth_type

And on the right hand side, put in this value: expr {"1"}

This should enable 2-factor prompt.

Also, keep in mind that 11.6.0 HF4 now supports native StoreFront protocol integration - no more legacy mode needed.
