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.
This trick is common enough and trivial to reverse engineer. I can just purge my billion-email-address hacked list of all characters between a + and an @ and have a clean list that untraceable with your system.
