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.
I seem to remember that the passwords were encrypted so, all they got was the passwords people use for their password manager which because people were using the password manager and therefore had random passwords it didn’t really matter hugely.
