Every dial, exposed.
Set exact character rules, or lay the password out piece by piece with a simple pattern such as W-W-NN-S.
Generated in your browser with the Web Crypto API. Nothing is sent or stored.

Generate several at once
Choose 5, 10 or 20 to compare candidates side by side. Nothing is stored — the list disappears when you close the tab.
The pattern language
Patterns are deliberately tiny and safe: W is a word, U an uppercase letter, l a lowercase letter, N a number, S a symbol and X any selected character. Everything else is copied through as literal text. There is no scripting, no variables and nothing that could be executed.
Fixed text costs you
A prefix or suffix adds length but no randomness, so KeyMint leaves those characters out of the entropy figure entirely. If a site needs a fixed marker, add extra random characters to make up for it.
Generated entirely in your browser
KeyMint never receives your passwords. There is no account, no database, no server-side generation and no password history. Close the tab and everything you generated is gone.
Nothing is transmitted
Passwords are never sent anywhere — not to KeyMint, not to an analytics service, not to a breach-checking API, and never placed in a URL.
Nothing is stored
No local storage, no cookies, no IndexedDB. Pinned passwords live in the page's memory and vanish when you close it.
Real randomness
Every choice comes from crypto.getRandomValues() with rejection sampling, so no character or word is more likely than another.
Other ways to make a password
Each mode is the same generator with a different shape. Nothing you make in one is carried into another.
Strong Random
The strongest general-purpose choice. Best when a password manager stores it for you.
Passphrase
Several random words. Easy to remember, easy to type, strong when you use enough of them.
Readable
Real words with controlled substitutions. Trades some randomness for memorability.
Pronounceable
Invented but sayable syllables. Useful when you must type it by hand on another device.
PIN
For locks, cards and devices that only accept digits.
