If you use LastPass, you should take the Security Challenge. It will scan your vault for compromised, weak, reused, and old passwords and recommend passwords you should change. LastPass will give you a numerical security score, too.
Why? Old, weak passwords are a risk. There are computers that have been set up exclusively to crack your easy passwords so that the internet bad guys can get into your accounts. Take the challenge. And if you don't use LastPass, see if your password manager has a similar tool. If you are not using ANY password manager, learn more about LastPass here. https://tinyurl.com/y2uw8te2
