A long-awaited feature requested by many users it’s now available: a strong random password generator. Generating long, high-quality random passwords is not simple. Now, when you need to create a new password, click on the new button that you find on the right of any password field. The small pop-up window below will appear, select the pools of characters to be used in the new password and click OK. That’s all.

It’s a very simple tool designed to securely generate password with an estimated entropy of at least 128 bits. Therefore password length will range from 19 to 26 characters, depending on how large is the pool of allowed characters.

Unfortunately some web sites have password policies that limits the length to fewer characters. In those cases simply delete a portion of the generated password to achieve the desired length. The password strength indicator will change accordingly: from the original bright green to less reassuring colors.

Please note that the entire source of randomness in this tool is Fortuna, the same cryptographically-strong pseudo random number generator used throughout Clipperz.

Memorable and pronounceable passwords are nice, but strong and long random passwords are secure! The use of these maximum-entropy passwords minimizes (essentially zeroes) the likelihood of successful “dictionary attacks”.
