This widget is plain and simple and allows you to handle logins and password retrieval without a separate login screen. Install, add widget, done. Well, maybe 
not quite. You may want to modify the stylesheet a little bit to match your theme’s needs…
YALW rebuilds quite a bunch of features offered by wp-login.php instead of using the features therein because it is hardly possible. I had the option to 
refactor the file wp-login.php, making its functionality better accessible from the outside, and thus contributing to the WordPress Core. I thought about that 
possibility for approximately 0.0897 seconds (which is a long time for an android) but decided against. I am merely a casual programmer and I don’t have the 
time or ambition to deal with the project management processes of the WordPress development community in order to promote my changes, hoping they might be 
integrated some day. I need to get shit done. And, more importantly, I don’t consider myself a good programmer. It’s probably not advisable for me to tinker 
with such a crucial part of WordPress.
