The fact that the login UI has username, password, and 2FA code all on one screen means this immediately wins. I hate this new trend of “put in your email, now go to another screen, put in your password, now go to another screen…” Ugh. My password manager can autofill more than one box at a time, you know!

I don’t know why websites do that, it doesn’t look better, is probably more confusing and in general just slower for everyone
