I'm using Lastpass and Authenticator connected on my PC and mobile. When I login to Lastpass on my PC, Authenticator on my mobile asks for verification. But on verification screen there is not much, just email address, but this can be someone else typing my email. I know that odds are astronomic but someone may click accept accidentally and let an attacker get in.
I'm sure there are more security checks but it would be great to display some Device Identifier on Authenticator screen of which device requested to login. This could be a nickname i gave to my PC, IP address, City/Country e.t.c.
