Many passwords used by real users have been leaked and become public knowledge through networks of password crackers (some malicious, others less so). These leaks are due to poor security measures by other web sites (including high profile sites such as Yahoo!, Sony and LinkedIn). Unfortunately, these passwords are now public knowledge among groups who would like to steal data from your Wise Owl Legal Appliance.
Wise Owl Legal take proactive measures in protecting your password by obtaining as many of these leaked passwords as possible and placing them on a large blacklist. We are constantly updating and adding to this list. In mid 2013 it consisted of 50 million passwords. . The only way to find out of your password is on the black list is to attempt to change it (TODO: provide some public means of querying the blacklist perhaps??). Wise Owl recommends using a strong password for your account.
