More about this tool

The Password Generator creates random passwords of a chosen length directly in your browser. You can include lowercase and uppercase letters, digits, symbols, exclude similar characters, use presets, and generate one or many passwords. It is useful for one-off signups, test accounts, demo access, local development, and dev tokens. Generation runs locally in your browser, and your password is not sent to the UtiLab server. After copying, save it in a password manager because the service does not store or restore results.

Frequently Asked Questions

How do I generate a password?

Choose the length and character sets, then click "Generate password". Copy the result and save it in a password manager.

Is my password sent to the server?

No. The password is generated locally in your browser and is not sent to the UtiLab server.

What password length is reasonable?

For everyday accounts, 12–16 characters is common. For important passwords, 20 or more is better. Longer passwords with broader character sets are stronger.

Can I create a password without symbols?

Yes. Disable symbols or choose a "No symbols" preset when a site rejects special characters.

What does exclude similar characters mean?

It removes characters that are easy to confuse when typing manually, such as 0, O, o, I, l, and 1.

Can I generate several passwords at once?

Yes. Set how many passwords you need and copy them as a column, comma-separated list, or JSON.

Can I use the password as an API key?

For dev and tests you can generate a random string or token. For production secrets, use backend crypto and a secret store.

Does UtiLab store generated passwords?

No. Passwords are not stored or sent to the server. After closing or refreshing the page they cannot be recovered.

What is crypto random?

Crypto random is the browser cryptographic random source. It should be used for password generation instead of Math.random.

Do I need to register?

No. The tool works immediately without registration.
