Password Generator
Generate strong, unique passwords instantly. 100% client-side — never sent to any server.
🔒 All passwords are generated locally in your browser using crypto.getRandomValues(). Nothing is transmitted to any server.
About the Password Generator
This password generator creates strong random passwords with adjustable length and character sets. Generation uses your browser's cryptographic random source, and nothing is ever transmitted, logged or stored — the only acceptable arrangement for a tool that produces secrets.
A password generator removes the weakest link in password security, which is human invention. People reuse, substitute predictable characters and build passwords around words — all patterns that cracking tools exploit first.
Length matters far more than complexity. Each additional character multiplies the search space, so a long password drawn from a smaller set beats a short one stuffed with symbols. Sixteen characters is a reasonable floor for anything important, and twenty or more for a password manager's master password.
Because generation happens in your browser using the cryptographic random source, no password is ever transmitted or recorded — which is the only acceptable arrangement for a tool like this. Store the result in a password manager rather than reusing it anywhere.
How to use the Password Generator
- Set the length. Choose at least 16 characters for anything important.
- Pick the character sets. Include uppercase, lowercase, digits and symbols as the site allows.
- Generate. A new password is produced from the browser's secure random source.
- Save it to a manager. Copy the password straight into a password manager rather than reusing it.

Frequently asked questions
How secure are the generated passwords?
They come from crypto.getRandomValues, the browser's cryptographic random source, rather than the ordinary Math.random generator. That distinction matters: Math.random output is predictable from enough observations, which would make passwords far weaker than their length suggests.
How long should a password be?
Sixteen characters or more for anything that matters, and let the generator pick them. Length contributes more than complexity — a long random password beats a short one decorated with symbols.
Why exclude ambiguous characters?
Because capital I, lowercase l and the digit 1 look identical in many fonts, as do O and 0. Turn the option on for any password you might have to read aloud or type from a screen; leave it off for one going straight into a password manager.
Are the passwords stored or sent anywhere?
No. Generation happens in your browser and nothing is transmitted, logged or recorded — the only acceptable arrangement for a tool that produces secrets. Reload the page and they are gone.
Where should I keep the password?
In a password manager, and use it in exactly one place. Reuse is what turns one site's breach into a problem everywhere else, and no amount of password strength protects against it.
