Password Generator

Generate strong, random passwords in your browser using a secure random generator. Choose length and character types, exclude ambiguous characters, and copy — nothing is sent or stored.

Runs entirely in your browser — nothing you type is uploaded.

Note: passwords are generated in your browser with JavaScript and a secure random generator. With JavaScript off you can read this guide, but the generator controls will not appear.

Generate strong, secure passwords

This tool creates strong, random passwords entirely in your browser using the cryptographically secure random generator (crypto.getRandomValues), never the ordinary Math.random. Choose the length and character types, and copy your password — it is never sent to a server or saved anywhere.

How it works

  1. Choose a length from 8 to 128 characters (16 is a good default).
  2. Pick character types — uppercase, lowercase, numbers and symbols.
  3. Optionally exclude ambiguous characters (I, l, 1, O, 0, o).
  4. Click Generate, then copy your password. Generate again for a new one.

Features

  • Cryptographically secure — uses the browser\'s secure random generator, not Math.random.
  • Guaranteed variety — includes at least one character from each selected type, then shuffles.
  • Readable option — exclude ambiguous characters for easier typing.
  • Strength estimate — based on length and the character types you choose.
  • Private — nothing is uploaded, stored or shared.

Password tips

Use a long, unique password for every account, and prefer a reputable password manager to store them. Longer passwords with more character types are harder to guess. Avoid reusing passwords or basing them on personal information.

Limitations

The strength label is an estimate based on length and character variety — no password is ever guaranteed unbreakable. Real-world security also depends on where and how you store and use the password.

Privacy

Passwords are generated locally in your browser and are not sent to a server. Nothing is written to browser storage or cookies, and the tool makes no network requests.

Frequently Asked Questions

How random are the passwords?
Each password is built with the browser's cryptographically secure random generator (crypto.getRandomValues) — not the ordinary Math.random. Characters are chosen without bias and the final password is securely shuffled.
Are my passwords sent anywhere or saved?
No. Passwords are generated locally in your browser and are not sent to a server. Nothing is written to localStorage, sessionStorage, cookies or any external service.
Does it include a character from every type I select?
Yes. When you select multiple character types, the generator guarantees at least one character from each selected type (when the length allows), then fills the rest randomly and shuffles. If the length is too short for the selected types, it shows a clear error.
What length should I choose?
You can pick from 8 to 128 characters; the default is 16. Longer passwords with more character types are stronger. The strength label is an estimate based on length and the character types you choose — no password is ever guaranteed unbreakable.
What does "exclude ambiguous characters" do?
It removes easily confused characters (I, l, 1, O, 0, o) so passwords are easier to read and type without mistakes. It is optional.
