Generate a strong password in seconds
A password generator is a software tool that automatically creates strong, random passwords for you. Instead of trying to invent a complex password yourself, a password generator uses random characters to create passwords that are difficult to guess.
At PassGen, we provide a free and easy-to-use password generator that helps you create strong and unique passwords for your online accounts.
Weak passwords can make online accounts easier to compromise. Common passwords such as "123456" or "password" are especially easy to guess.
A strong password should be long, unique, and difficult to predict. Using a different password for every account also helps reduce the impact of a compromised password.
PassGen generates passwords directly in your browser using cryptographically secure random number generation through the Web Crypto API.
You can customize your password by selecting which character types to include:
You can adjust the password length from 4 to 40 characters. Longer passwords generally provide greater resistance to guessing attacks.
Password entropy is a measure of how unpredictable a password is. It is influenced by the length of the password and the size of the character set used.
For example, a long password generated using uppercase letters, lowercase letters, numbers, and symbols has more possible combinations than a short password using only lowercase letters.
Generating a strong password is only one part of good online security. Follow these password security practices:
Password reuse can increase your security risk. If a password is exposed in a data breach, attackers may attempt to use the same credentials on other websites.
Using a unique password for every account helps limit the potential damage if one password becomes compromised.
