Password Generator
Create strong, secure passwords instantly. Runs entirely in your browser — no passwords are ever sent or stored anywhere.
About the Password Generator
The World Utility Hub Password Generator creates strong, random passwords instantly using your browser’s built-in cryptographic random number generator. You can choose your password length anywhere from 6 to 64 characters, and select which character types to include: uppercase letters, lowercase letters, numbers, and symbols. There is also an option to exclude visually ambiguous characters like the number zero and the letter O, or the lowercase letter l and the number 1, which is useful when you need to read or type a password manually.
Every password is generated entirely on your device. Nothing is sent to any server, nothing is stored, and no account or sign-up is required. You can generate as many passwords as you need, copy them with one click, and use the multiple password generator when you need to set up several accounts at once. The strength indicator shows you in real time how secure your password is, along with the entropy score in bits, which is the technical measure of how unpredictable and difficult to crack the password is.
Frequently Asked Questions
What makes a password strong?
A strong password is long, random, and uses a mix of character types. Length matters most: a 16-character password is exponentially harder to crack than an 8-character one, even if both use all character types. Using uppercase, lowercase, numbers, and symbols together dramatically increases the number of possible combinations, making brute-force attacks impractical. Avoid dictionary words, names, dates, or any pattern that could be guessed.
Is it safe to use an online password generator?
Yes, as long as the generator runs locally in your browser, which this one does. Passwords are created using the Web Crypto API built into your browser and never leave your device. There is no network request, no server involved, and no logging of any kind. You can even disconnect from the internet after the page loads and the generator will still work perfectly.
How many bits of entropy does a strong password need?
Security professionals generally recommend at least 60 bits of entropy for everyday accounts, and 80 or more bits for sensitive accounts like banking or email. A 16-character password using all four character types typically achieves over 100 bits of entropy, which is considered extremely strong. The entropy display on this tool updates as you adjust your settings so you can see exactly how secure your chosen configuration is.
Should I use a different password for every account?
Yes, without exception. When a website suffers a data breach, attackers immediately try the stolen passwords on other popular sites. If you reuse passwords, a breach at one site puts all your other accounts at risk. Generate a unique strong password for each account and store them in a reputable password manager such as Bitwarden, 1Password, or your browser’s built-in password manager. You only need to remember one master password, and the manager handles the rest.
