I don't think the "Did you mean [...] ?" popup should block the password box. Maybe it should appear on the top instead? My email address uses a .io domain and it suggested the .com domain. Since it blocks the password box, it seems like it's assumed that the suggestion is correct, and that I'll click the box before continuing.

Aside from that, it looks great of course. I think that goes without saying.

EDIT: I don't think that this was really a call for feedback, but there's my two cents either way.
