Joel's Password Generator is a free Chrome add-on developed by jtwalters. This password generator is designed with security and password-memorability in mind. Inspired by the xkcd Password Strength comic, it provides users with ten relatively complex, yet easy to remember passwords.

With this extension, users have the option to include numbers or symbols for additional complexity, or to satisfy certain password requirements. They can also adjust the number of words used in the generated passwords.

The use of common words in the passwords aids memorability, while the use of multiple words ensures sufficient complexity to prevent guessing. The generator uses the Stanford Javascript Crypto Library, a derivative of Ferguson and Schneier's generator Fortuna, to provide random values.

Overall, Joel's Password Generator is a useful tool for creating secure and memorable passwords. It offers a simple and straightforward interface, making it accessible to users of all levels of technical expertise.
