What's the best way nowadays to protect yourself as a user against this? You certainly can't trust anyone to store your password securely, so you're forced to have a strong password per site, and it's impossible to memorize that many passwords.

I'm currently using Password Hasher (https://chrome.google.com/webstore/detail/password-hasher-pl...), but that only works well because I mostly use just one machine.
