<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I essentially tried your suggestion: I made a dummy context called urn:mace:incommon:uiuc.edu:authn:password. The SP didn’t know about or ask about it. In fact,
I didn’t even list it as an accepted context for the MCB’s handler definition in handler.xml. It had the same method as the usual password method, though.<o:p></o:p></span></p>

<p class="MsoNormal">Wouldn't think it is the MCB Duo module's "fault", because either it gets invoked or not. It comes down to whether the MCB can currently support the full complexity of use cases some deployers are trying.<o:p></o:p></p>

<p class="MsoNormal">If the user had already done password, and the service requesting indicated it only accepted Duo, it will require the user to do Duo. The reported problem seems to come in when the user has already done password as the initial context,
and the service will accept either, with Duo listed first. The user is not getting presented the choice to do/"add" Duo.<o:p></o:p></p>

<p class="MsoNormal">Does playing games with the two different password contexts, :Password versus :PasswordProtectedContext, make any difference? Listing :Password for initial context, and then having :PasswordProtectedContext as a later context with the same
method, and having the service list :PasswordProtectedContext as the 2nd choice? Probably won't make a difference, since both are satisfied by the same method.<o:p></o:p></p>
