Is there reason to believe that's significantly more secure than just re-using the same (strong) password everywhere?
Personally, I'd feel safer with a unique strong password for every site, even though it effectively requires a password manager (and trusting that password manager). So far, i think most attacks don't usually involve your local computer, people aren't attacking your laptop trying to crack your password manager (I think? Any known attacks of such? I guess I'd assume the NSA probably _is_, but anyway, regardless, I'd rather have unique strong passwords).
I am on my phone and lazy so excuse missing sources. But afaik a lot of malware targets password managers. Dont forget that some of these also are really really bad and easy targets. some bigger ones may be good, but still tend to fail from time to time.
a unique password for every site is defintly better, but not if these passwords are saved anywhere.
My sheme, which only exists in my head, imo provides therefore more safety.
honestly i am just paranoid, but the way some users use password managers scares me.
"Scheme". It's pronounced like "skeem", not "sheem".
