Perfect Authorization

In the era of vebdvanolnosti surprises that the forms for authorization on the site do not evolve. As they were 10 years ago on Hotmail, two fields and a button remain to this day.
I propose to improve the authorization process, reducing the form to a minimum: leave one field.
The bottom line is that the user consistently enters the same username and password into the same field, double-clicks Enter and enters the site. This saves space on the site and decreases the number of button presses.


As an example, made such a mold .
It would be interesting to hear opinions.
