Sure, but people with PW managers are reducing their long-term inconvenience by paying a little bit up front. I don't use a PW manager for any security benefit but because it makes it easier to sign into things.

Hell, I store my 2FA keys in my pw manager and have it autofill those too -- a reduction in security! But there are some services that refuse to not spam your phone number if you don't set up some 2FA.
