About SecurePass
SecurePass is a free suite of password tools built around one simple principle: your secrets should never leave your device. Every tool on this site — the password generator, strength checker, passphrase generator, and PIN generator — runs entirely in your browser using JavaScript.
What this tool does
SecurePass helps you create and evaluate strong, random credentials. Generate a password of any length with the exact character types you need, build a memorable passphrase from random words, produce secure numeric PINs, or check how strong an existing password really is.
How it works
All generation happens client-side using crypto.getRandomValues(), the browser's
cryptographically secure random number generator. Nothing you type or generate is transmitted to any
server, saved to a database, or written to a log. You can confirm this yourself: disconnect from the
internet and the tools keep working perfectly. When you close the tab, the data is gone.
Who built it
SecurePass is built and maintained by an independent developer who believes good security tools should be free and accessible to everyone. The site is kept running through unobtrusive advertising.
Free & ad-supported
SecurePass is completely free to use. To cover hosting and development, the site displays ads. We never sell user data — in fact, the tools don't collect any password data to sell. Read more in our Privacy Policy.
