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.
LastPass is the maximum shit. They got hacked like 3 times in a year and my company‘s password notes got leaked.
We are now with Bitwarden and this was the biggest security hardening measure we have taken.
Make sure whatever password manager you use doesn’t store the key on their servers. Bitwarden does this correctly (if you lose your PW, Bitwarden can’t recover it), and I’m sure some competitors do as well. LastPass apparently didn’t.
