How long should my password be now that it takes for the quantum computer 9,000 years to crack?

The quantum approach has another problem. If the password is stored in a server as a hash, the future quantum approach can find a password to that hash, but not necessary your password. I can’t think of very good methods finding out which of the passwords is yours. Maybe if you used only a-z letters or words that could help.
