PasswordBox, the password management tool that recently raised funding, has acquired Legacy Locker, a five-year-old service that allows people to store an encrypted page of passwords and important documents to share with loved ones when they die. One interesting part of the deal (terms were not disclosed) is that all info from Legacy Locker accounts will be deleted, as it was deemed unwise to port an encrypted database. Users will have the option to reregister for the service as part of PasswordBox.
