Details of the process
Use our service to generate super strong passwords or pseudo-random numbers.

The generated passwords are extremely difficult (~impossible) to guess or crack, the numbers are great for lotteries, sweepstakes, holding drawings, scientific applications, and online games. Just select your preferred options then click on the yellow GENERATE button. As for the passwords, the more options you choose, the more secure the passwords will be.

Most importantly, both the passwords and numbers are generated securely inside your browser (via JavaScript) and are not transmitted from/to our servers.

Using a strong password lowers the overall risk of a security breach and it's strength is a measure of the effectiveness against guessing or brute-force attacks. Our tool calculates how many combinations an attacker (who does not have direct access to the password) would need, on average, to guess it properly. Keep in mind, the strength of a password is a function of length, complexity and unpredictability.

Our pseudo-random number generator based solely on deterministic logic and can never be regarded as a "true" random number source in the purest sense of the word, but in practice it is generally sufficient even for demanding security-critical applications.
