This is how all companies should handle potential security breaches

LastPass, the secure, online encrypted password management service does it right. "...It's prudent to assume where there's smoke there could be fire."  That's LastPass's motto.  When their internal log files revealed an unexplained increase in traffic from one of their databases on Tuesday, LastPass notified its users and immediately required everyone to verify their account and change their master password. Way to be transparent, prompt, and open with your users in the face of a security breach, unlike some other companies.
