About the Password Generator
Need a password that won't turn up in a breach list? This free random password generator builds strong, unpredictable passwords using your browser's cryptographically secure random source (crypto.getRandomValues) — not a guessable pseudo-random shortcut. Set any length from 4 to 128 characters, toggle uppercase letters, lowercase letters, digits and symbols independently, and optionally exclude ambiguous characters like O, 0, l and 1 that are easy to misread when typing a password by hand.
Privacy comes first: every password is generated locally on your device and never sent, logged or stored anywhere. A built-in strength meter rates each result as you tweak the settings, so you can see immediately how much extra length and character variety improve security. When you're happy with the result, copy the password with one click and paste it straight into your password manager, router setup or new account form.

Frequently asked questions
Is this password generator safe to use?
Yes. Passwords are produced with crypto.getRandomValues, the same cryptographically secure random source browsers use for encryption keys, and generation happens entirely on your device. Nothing is transmitted, logged or stored, so no one — including us — ever sees a password you create here.
How long should my password be?
For important accounts, aim for at least 16 characters with all four character sets enabled. Every extra character multiplies the number of possible combinations, so longer is dramatically stronger. If a site limits symbols or length, keep the length as high as it allows and watch the strength meter for feedback.
What are ambiguous characters and why exclude them?
Ambiguous characters are ones that look alike in many fonts, such as capital O and zero, or lowercase l and the digit one. Excluding them slightly reduces the character pool but makes passwords far easier to read out or type by hand — handy for Wi-Fi keys and temporary passwords.
Can I use this for Wi-Fi passwords and PINs?
Absolutely. For a Wi-Fi key, generate a long password and consider excluding ambiguous characters so guests can type it easily. For a numeric PIN, disable everything except digits and set the exact length you need. The same secure random source is used for every combination of settings.
Are the generated passwords stored anywhere?
No. Each password exists only in your browser tab until you copy or regenerate it. There is no server call, no analytics event containing the value, and no history kept. If you close the page without copying, the password is gone for good — so save it to a password manager first.
