That's an interesting question, I've actually not considered 2FA with BW (or 1PW for that matter). My knee jerk reaction is that I want a seamless interaction and 2FA can be a bit jarring. In all honesty, I've not tried it with BW, so I may take a look at that.
As for 1PW, I notice that it struggles at times on some forms. If the login form is presented like it is from alamo rental car, it doesn't fill in. I click the email address text box, nothing. I click on the little 1PW icon, the sign-in window disappears. Alamo isn't the only website I see 1PW do this, but I was logging in this morning and well 1PW was giving me issues
Its not a huge problem, but its an oddity.
