I'm just asking myself, why not use the Password generator + manager always if you have it installed either way. I've also used some of my digit-only 8-char passwords for some websites where I'm just indifferent about people logging into my account, but usually I just use the PW manager. It take maybe 1-2 more clicks, but more importantly, it saves me from the website saying "ohhh noooo please add a special character", and then "ohhhh sorry but theres no upper case character", blah blah.

By always using the PW manager I have a clear and standard route of registering accounts that is not a lot more work, is way more safe by default, and also can save time if at some point in 2 years you want to log in again, because of some random event. Sure, email reset would be possible, but that takes time again.

Another counter-argument against the article in general, at least in my opinion: while 2FA adds a time consuming step to the login, it happens rarely. I use a lot of services and usually always enable 2FA if it has even a single bit of personal or critical data. But as soon as I'm logged in, the access tokens or refresh tokens are valid for such a long time that I rarely have to do the 2FA challenge again.
