As someone who does use a password manager, there's nothing more annoying than a service that doesn't accept email/password logins. I don't want to cede my auth to a 3rd party, clutter up my inbox with magic links, or have to keep careful track of passkeys that are tied to a device and can be easily lost!
Sure there is! Websites that disable pasting into password fields “for your security” are even more annoying.
(Pro tip: lapcat referred to his Stop The Madness software here. It fixes this and other dumb website anti-features. Don’t leave your home page without it.)
