StrongPasswordGen.org exists to make the single most effective security habit — using a unique, random password for every account — effortless. Our generators create cryptographically secure passwords, memorable passphrases, PINs, and usernames in one click, free and with no signup.
Every tool on this site runs entirely in your web browser using the Web Crypto API (crypto.getRandomValues), the same cryptographic random source trusted by password managers. Nothing you generate is ever sent to, seen by, or stored on our servers — you can even load a page, disconnect from the internet, and keep generating. That architecture is not a marketing claim; it is simply how the site is built, and anyone can verify it by inspecting the page source or watching the network tab.
Why random passwords matter: attackers do not sit and guess — they run billions of attempts per second against leaked password databases, using every word, name, date, and keyboard pattern humans favor. A truly random 16-character password is beyond the practical reach of that hardware; a clever-feeling password based on a word and a birth year is not. Our strength checker shows the math for any password pattern you're curious about (without ever transmitting it).
The site is supported by unobtrusive advertising, which keeps every tool free. You can also embed the password generator on your own website at no cost.
