The trend towards having the username and password on two separate pages is realllllly annoying.

While trying to work out why web designers are doing this I came across this page (https://www.twilio.com/blog/why-username-and-password-on-two-different-pages) which basically seems to conclude it isn't necessary and just confuses people and auto-type password managers.

Anyone here run a website that does this? Why? Do you hate your users?
