Password Generator
Generate strong, random passwords with a cryptographically secure generator. Choose length and character sets — nothing leaves your browser.
- ✓ Runs in your browser — nothing uploaded
- ✓ No sign-up
- ✓ Free, no limits
This strong password generator creates random, secure passwords using your browser's built-in cryptographic random number generator — the same crypto.getRandomValues API security software relies on, not a predictable shortcut. Choose a length from 8 to 64 characters, tick the character sets you want (lowercase, uppercase, digits, symbols), and every password is guaranteed to include at least one character from each set you enabled.
A built-in strength meter rates each password from Very weak to Excellent using zxcvbn, the estimator developed at Dropbox that checks against common words, keyboard patterns and known password lists — so you see immediately whether a password would survive a real cracking attempt. For most accounts, 16 characters with all four sets enabled is a strong default; go longer for anything critical.
Crucially, passwords are generated entirely on your device. Nothing is transmitted, logged or stored — you can load the page, turn off your Wi-Fi, and it still works. Copy the result with one click and store it in a password manager rather than reusing it across sites.
Frequently asked questions
Is it safe to use an online password generator?
It is safe when generation happens in your browser, as it does here. The password is created on your device with the Web Crypto API and is never sent to any server — you can verify with your browser's network tab.
How long should a password be?
At least 16 characters with all four character sets is a strong default for most accounts. Length matters more than complexity: every extra character multiplies the effort needed to crack it.
What does the strength meter measure?
It uses zxcvbn, which estimates real-world guessability by checking dictionary words, names, dates, keyboard patterns and leaked-password lists — far more realistic than counting character types alone.
