Duo two-factor authentication is required for Perceptive Content and Perceptive Experience. The deviation from the norm is that the Duo screen you typically see on other software using Duo will not show up on your screen. Instead, Duo will automatically process the default method you have set in Duo. In other words, if you have Duo set to automatically send a PUSH to your cell phone, it will do so without prompting on the computer screen, "please check your phone".
To force a Duo response method, replace your password with the following based on the Duo method you'd like:
Phone PUSH: Enter your password with a comma and then the word "push" (ie: mypassword,push)
KeyFOB: Enter your password with a comma and then the number from the keyfob (ie: mypassword,123456)
YubiKey: Enter your password witt a comma and then press the YubiKey (ie: mypassword,casdasdvasdfasdraseasdf)
