email watchdog

i recently blogged about how safe is your password, and mentioned the shouldichangemypassword.com website. in the past, you could have placed yourself on their mailing list to be notified each time they find out about new compromises in general. the evolution of this passive monitoring to a new active monitoring service is called email watchdog, which

keeps an eye out for your email address and password, and will immediately notify you if they are compromised in any future breaches that [they] identify.

you can sign up to watch up to 10 email addresses for free.
