Note that the "action" button (square box with up arrow) also provides access to other actions unrelated to password manager (e.g. printing). Having access to "print" through the keyboard may seem strange.

I don't think adding anything but password managers is part of the request, but the question is how would we know if they are installed? We could hard-code the top two or three on the appStore, but that becomes a maintenance headache (unless we make the list server updatable). 

I was thinking of having the password manager all add the same scheme to their app.
They already conform to one API regarding the extensions, it's not unrealistic to asks them to add a scheme.

FYI the list needs to be baked in the app's plist.

Not sure how current this request is and how it aligns with our UI plans for access to password manager UI on iOS.
Adding nepper@: FYI.
