Password Generator

Why use a password generator?

Most account breaches do not happen because a hacker is some genius cracking advanced encryption. They happen because someone, somewhere, reused the same password they had been using for years. When a website you signed up for in 2014 finally gets hacked, attackers grab millions of email-and-password pairs and quietly try them on every popular service — banks, email, social media, shopping sites. If you reuse passwords, even one old leak can open the door to your entire digital life. A password generator solves this in the simplest way possible: it gives every account a unique, unpredictable password that no human would ever invent.

What makes a password actually strong

Strength comes from two things working together: length and randomness. A 6-character password mixing letters, numbers and symbols can be guessed by modern hardware in seconds. A 16-character random password jumps that effort into the trillions of years. That is why this tool lets you slide all the way up to 64 characters — for anything truly important, like your email or password manager master key, longer is always better. Mixing in uppercase letters, digits and symbols multiplies the number of possible combinations, but length matters more than variety. A long, all-lowercase passphrase will usually beat a short, complex one.

How this generator stays safe

Every password you see here is built using crypto.getRandomValues, the cryptographically secure random source built into your browser. That is the same quality of randomness used by HTTPS, secure cookies and modern authentication libraries. We never call Math.random, which is predictable and unsuitable for anything sensitive. More importantly, your generated passwords never leave your device. There is no server, no log, no analytics event, no network request when you click Regenerate. Open your browser's developer tools and check the Network tab — you will see nothing happen, because nothing should.

A practical workflow

Pair this tool with a real password manager such as Bitwarden, 1Password or your browser's built-in vault. Generate a fresh password here, copy it, paste it into the signup or password-change form, and let your manager save it. From that moment on, you never need to memorise it. The only password you should actually remember is the master password to your manager itself — and for that one, use a long, memorable passphrase made of four or five unrelated words you can picture in your head.

Common mistakes to avoid

Do not write generated passwords on sticky notes or save them in a plain text file on your desktop. Do not email them to yourself. Do not keep them in your phone's notes app without a lock. Treat each generated string as a tiny key to a real lock, because that is exactly what it is. With a generator and a manager combined, strong unique passwords stop being a chore and become invisible.
