Generate a strong password in seconds
A password generator is a software tool that automatically creates strong, random passwords for you. Instead of struggling to come up with a complex password yourself, a password generator uses algorithms to produce passwords that are virtually impossible for hackers to guess. At PassGen, we provide a free, secure, and easy-to-use password generator that helps you protect your online accounts.
Weak passwords are one of the leading causes of data breaches worldwide. Hackers use sophisticated tools to guess or crack passwords, and if your password is too simple — like "123456" or "password" — it can be cracked in seconds. Using a secure password is the first line of defense against unauthorized access to your accounts. PassGen helps you create passwords that are long, random, and unique, making them highly resistant to brute-force attacks.
PassGen generates passwords directly in your browser using cryptographically secure random number generation (via the Web Crypto API). This ensures that every password you generate is truly random and unpredictable. You can customize your password by selecting which character types to include:
You can also adjust the length of your password from 4 to 40 characters. Longer passwords are exponentially more secure, and we recommend using at least 16 characters for maximum protection.
Password entropy is a measure of how unpredictable your password is. It is calculated based on two factors: the length of your password and the size of the character set used. The higher the entropy, the stronger the password.
For example, a 16-character password using uppercase letters, lowercase letters, numbers, and symbols has significantly higher entropy than an 8-character password using only lowercase letters. PassGen includes a strength indicator that shows you how strong your password is — from "Weak" to "Very Strong" — so you can adjust your settings accordingly.
Generating a strong password is just the first step. To stay safe online, follow these password security best practices:
Password reuse is one of the most dangerous habits you can have online. When you use the same password across multiple accounts, you're essentially handing hackers the keys to your digital life. If one service you use suffers a data breach, attackers will try that same password and email combination on other popular services like Gmail, Facebook, and banking apps.
PassGen makes it easy to create a unique, strong password for every account you have. No more struggling to remember complex passwords — simply generate a new one, copy it, and save it in your password manager.
A password generator is a tool that creates random, secure passwords based on your chosen criteria. It helps you generate strong passwords that are difficult for hackers to guess or crack.
Using a password generator ensures you create strong, unique passwords for each account. This significantly reduces the risk of password breaches and protects your online identity.
Yes! PassGen generates passwords entirely in your browser using cryptographically secure random number generation. We do not collect, store, or transmit any data. Your passwords are never sent to our servers or any third-party services.
Password entropy measures how unpredictable a password is. The higher the entropy, the stronger the password. Entropy is calculated based on the length of the password and the size of the character set used.
For maximum security, we recommend passwords that are at least 16 characters long. They should include a mix of uppercase and lowercase letters, numbers, and special symbols.
Absolutely not! You should never reuse passwords across multiple accounts. If one account gets compromised, hackers will try the same password on other services. Always use a unique password for each account.
Yes! PassGen is 100% free and open-source. There are no hidden fees, subscriptions, or limitations. If you find the tool useful, you can support us via Buy Me a Coffee.
The best way to keep your passwords safe is to use a password manager that encrypts your passwords and autofills them on websites. Additionally, enable two-factor authentication (2FA) on all your important accounts for an extra layer of security.
