There are some websites that are both super aggressive about timing out your session and also make you play hide and seek for the login button. Of the sites I use frequently UPS used to be about the worst offender but the most recent version of their site does have a usable login link.
Vanguard is another one that drives me up the wall. Going to Vanguard.com doesn't have a sign in area to autofill with a password manager; you have to go to the personal investors page. And sessions are hard limited to 15 minutes so you have to jump through these hoops every time. I have the correct page bookmarked but even on that page the log in boxes don't appear until half way down.
