In a blog post today, password manager LastPass announced the introduction of LastPass Sentry, a new feature launched in partnership with PwnedList to help LastPass users "be proactive about their online security."

"With LastPass Sentry, we'll use PwnedLists's comprehensive (and growing) database of 24 million publicly leaked usernames and passwords to perform daily 'checks' against LastPass account email addresses to look for positive matches," the company states.

"Currently, PwnedList has gathered credentials from 931 data leaks, totaling over 23 million email address and password combinations," notes Softpedia's Eduard Kovacs.

"When a match is found between a their users’ credentials and information on the PwnedList database, LastPass will be able to send an email alert to the user in question, prompting that person to, hopefully, reset their password or passwords," writes Threatpost's Brian Donohue.

"LastPass is offering the unique service to its free and Premium individual customers, as well as to corporate Enterprise customers," writes InfoWorld's Woody Leonhard. "For Enterprise customers, both the individual and the administrator receive notifications that a match has been found."
