That just means that you have such a small number of passwords that you are much more unsafe that someone using a compromised password manager. I guarantee you your passwords have been leaked in individual website's breaches and that has exposed all your other accounts using the same credentials.
Possible, however: My personal strategy, much like i have a "junk email" address for signing up for random BS and a personal one for actually using is that i have a "junk password" that i sign up for unimportant services, and i guarantee it has been leaked many times. My important banking / amazon / etc passwords are indeed (slightly) unique and backed up by an digitally impenetrable firewall: pen and paper.
Granted, this is just for personal use, and i can totally see a use case for a password manager in a company / corporate environment.
Your password store is a single file, it can be encrypted, backed up (or not), distributed/synchronized between your devices (or not). It belongs to you, not to a third party.
The inevitable rejoinder is, "what happens if someone gets that file?" Well, what happens if someone gets your piece of paper?
> Well, what happens if someone gets your piece of paper?
Considering it's in my house there is short list of suspects, unlike exposing it to the entire world VIA TCP/IP, but yeah i get your point.
> Will you ever use a password manager.
Not for personal matters and that is a personal choice. My way ain't broke and i ain't fixin it. A password manager smells like something that could break, get compromised, or go out of business at any time without any warning and i don't like the smell of it.
I also code with Notepad++ with none of that autofill suggestion crap and doesn't take 8 smoking cores to fucking type a sentence if that tells you anything about my personality. Get off my lawn!!!
They're a random string of text unique to each site, I wouldn't even class them as 'my' passwords, just a derirative. Password Managers are a godsend (happy 1password user).
