I think two factor authentication should optionally be restricted to one device, preferably mobile.
Being able to use two factor from any of my devices with 1p installed is convenient, but removes one of the tenants of the feature: 'authentication by something I have'. Currently, two factor with 1p is barely more secure than a strong, generated password since they're stored and accessed together on any device.
Dream feature would be for the browser extension to send a prompt / notification to my mobile allowing me to get to the correct key quickly.
