Hi,
why information about user that doesn't exist when user write bad password is on the bottom? It is unvisible (red -but user look on the top of the screen)
In my opinion it is wrong - this information should be at the place where user look - at the top of scren.
User wrote bad pasword but don't know what happend and why cannot login. I know about it (my experience), because I wrote bad password but was looking on the top and didnt't see information which was at the bottom.

It is standard flash message position.
Password verification is made on form submit, hence shown via flash message

Thank you.
Maybe you should think about non standard position? It is my suggest only

There is something in my mind already
