Free Strong Password Generator

Create strong random passwords that never leave your browser

About Password Generator

There's only one way to have a truly random password: let a cryptographic random number generator make it, not your brain. This tool uses your browser's built-in Web Crypto API — the same source used for TLS keys — to generate passwords that have never existed before and are never sent to any server. Pick the length (16+ characters is a solid baseline), choose which character types to include, and copy with a single click. The entropy meter shows the theoretical cracking difficulty so you can see exactly what you're dealing with — and why a 20-character mixed password is essentially unbreakable.

How it works

1

Choose length and character sets

Set the length (16+ recommended) and pick uppercase, lowercase, digits, and symbols as needed.

2

Generate

A cryptographically random password appears instantly — click again to regenerate as many times as you want.

3

Copy and save

One click copies the password to your clipboard — ready to paste into a form or password manager.

Frequently asked questions

Are the generated passwords actually secure?

Yes — they come from your browser's Web Crypto API, a cryptographically secure random source. Nothing is sent to or logged by any server.

How long should my password be?

16 characters with mixed character sets is a strong baseline. Use 20+ for anything that protects money, sensitive data, or accounts you can't easily recover.

Should I include symbols?

Symbols add entropy per character, which helps when a site limits the total length. If symbols cause problems, a longer password with letters and digits is just as strong.

Is it free?

Yes — completely free, works offline once loaded, and has no limits.
