One of the earlier password managers, KeePass is free open-source software that will keep track of your logins. You can choose to use a master password to access the database, but the application has an option to use key files. KeePass says these files are more difficult to crack (just don't lose the file or the drive it's on). For the ultra paranoid, users can combine the two, requiring a master password and key file to unlock the password database.
Given its open-source nature, if you're not happy with any component, the source code is available for you to tweak and play with. KeePass is compatible with Windows machines; an unofficial port called KeePassX is available for Mac and Linux computers.
Norton Identity Safe: Password manager backed by big name in security
One of the newest players in this space, Norton Identify Safe debuted in the spring as a standalone product. While it's not the most robust password manager, for some people, the Norton name might offer peace of mind. The software uses 256-bit AES encryption and doesn't store passwords or decryption keys on the company's servers.
The big drawback is that Identity Safe doesn't use a built-in password manager; it only offers one through its website. In addition to saving and filling log-in information, Norton also offers bookmarklets to let users share content on social networks directly from Identity Safe. A safe search feature also alerts users to fraudulent websites (granted, most modern browsers have this built in). While Norton hasn't announced any pricing structure, users who download by Oct. 1 will be able to use it for free — no expiration date. Identity Safe is compatible with PCs and Macs as well as iOS and Android devices.
