Use the “passwords” feature to check if one of yours is compromised. If it shows up, never ever reuse those credentials. They’ll be baked into thousands of botnets etc. and be forevermore part of automated break-in attempts until one randomly succeeds.
That is assuming that someone will sit there and try to decrypt password rules for that specific person. Chances of that happening are basically 0, unless they are some sort of a high interest person.
