Actually, I don't understand what the "Create Application Password" portion had to do with me not being able to login. I visited that page on my WP.com settings screen and added an app called WordPress For iOS and tried to use the 16 digit password it gave me to login to WP.com in the WordPress mobile app and that didn't work. I'm pretty sure I'm totally misunderstanding what the Create Application Password is for.
