I would like the ability to use push notifications as my 2FA. It is a no brainier as this would also allow for yubikeys. It would also allow enterprise to better keep track and make use of this service. Lastpass supports it fully and it is fantastic. I go to log in and if I did not set it to allow this device for 30 days I click accept on the notification on my phone. Much easier and more convinient than putting a pin in every time I log in. With you lacking support with bridge this is the only barrier to my daily use of this service as it is an absolute pain to log in when it does not need to be.
