Are the passwords secure?

Yes. They are generated with crypto.getRandomValues(), the browser's cryptographic random source — not Math.random().

Is the Password Generator free?

Yes. It is free and open source with no login.

Is anything sent to a server?

No. Passwords are generated locally and never leave your device.

What makes a strong password?

Length and character variety drive entropy; the built-in meter estimates strength and crack time so you can choose well.

Can I generate several at once?

Yes. Batch mode creates multiple passwords in a single click.

About this tool

The Password Generator creates strong, truly random passwords using the browser's cryptographic RNG. Configure length and character types, exclude ambiguous characters, and watch a live strength meter with entropy and estimated crack time. Batch mode produces several at once — nothing ever leaves your device.

How to use it

Set the length. Choose a length between 8 and 128 characters.
Pick character types. Enable uppercase, lowercase, numbers, and symbols, and optionally exclude ambiguous characters.
Generate. Get a cryptographically secure password with a strength score.
Copy it. Copy the password, or generate a batch at once.
