Easy: I currently have 619 unique passwords, all but two auto-generated and difficult to memorize (because they tend to be 40+ characters and as random as practical). I've had at least four websites on which I've had an account experience publicly-known hash leaks, and in zero of those cases, nor any future cases, is my password hash likely to be easily cracked, and in the unlikely event that it is, the combination or username/email + that password doesn't work anywhere else, so it's of little to no value.

I use 1Password, though, so I'm not storing my passwords on someone else's computer in the same way LastPass does.

The ease with which password hashes are cracked advances steadily, and I wish more sites would let me supply them with 80+-character passwords.
