LinkedIn user data was jeopardized Wednesday when reports surfaced that 6.5 million passwords were leaked and posted on a Russian hacker site. Websites offering a LinkedIn password hack check likeLeakedIn quickly popped up so users could find out if their password was one of the 6.5 million – or more – leaked.

Don’t fret, all may not be lost if you’re one of the many who use the same password or a variant for your email and social networking logins. LeakedIn and LastPass, which also features a LinkedIn password check tool, enable users to check if their password was leaked. The sites change their LinkedIn password to a SHA-1 hash, which is then automatically compared to the 6.5 million-password database to determine if the password was hacked.
