The first screen asking for user name and the second screen asking for a password have identical color scheme. Our users get confused thinking that they are looking at the first (user name) screen again, and they call us that "the system didn't take my user name".
Also, the "click here" link for different authentication screen is visually not standing out, and users miss it all the time.
I would like to be able to customize the login screens (starting with a different color or layout scheme for the first and second one), and create a big obvious button for "Use two form authentication" or "click here to use google authenticator" or something like that.
Having the option to customize to that level of detail, or just having the defaults look different than they do now, would be great.
