LastPass users warned their master passwords are compromised
LastPass posted on their blog on Dec 28 that they identified a problem causing those emails to be incorrectly triggered:https://blog.lastpass.com/2021/12/unusual-attempted-login-ac..."However, out of an abundance of caution, we continued to investigate in an effort to determine what was causing the automated security alert emails to be triggered from our systems. Our investigation has since found that some of these security alerts, which were sent to a limited subset of LastPass users, were likely triggered in error. As a result, we have adjusted our security alert systems and this issue has since been resolved."
