Every account you create asks for a password, and the honest answer is that nobody can memorize a unique, random 20-character string for each one. That is what a password generator is for — but many of them are thin wrappers around weak randomness or a server you have to trust. BeastBrowser's Password Generator is different in the ways that matter: it runs entirely in your browser and draws on the operating system's cryptographically secure random number generator.

Hands-on with the tool, the first thing you notice is the feedback loop. As you drag the length slider or toggle the character sets, a strength bar and an entropy readout (for example, "129 bits · Very Strong") update in real time, so you can see exactly what each setting buys you. There are no accounts, no email gates, and no upsell prompts — you open the page and generate.

The page states its randomness source openly: crypto.getRandomValues(), which the tool notes is the browser's CSPRNG — the same class of randomness behind browser cryptography. That is a verifiable claim printed on the tool page itself, not marketing copy.

TL;DR

  • Truly local generation. Every password is produced in your browser using crypto.getRandomValues(); nothing you generate is transmitted to a server.
  • Real-time entropy readout. A live bits figure (e.g., 129 bits · Very Strong) plus a strength bar updates as you change length and character sets.
  • Full control over composition. A length slider plus individual toggles for uppercase, lowercase, numbers, and symbols — and a passphrase mode with memorable hyphenated words.
  • Free with no signup. No account, no email, no paywall; the tool works the moment the page loads.
  • One-click copy. A Copy button moves the generated password to your clipboard in a single click.

How to use it

  1. Open the Password Generator at https://security.beastbrowser.com/password-generator.
  2. The tool loads with a fresh password already in the output field, plus a strength bar and an entropy readout (e.g., "129 bits · Very Strong").
  3. Drag the length slider (default 20) to set how long the password should be.
  4. Tick or untick the Uppercase, Lowercase, Numbers, and Symbols checkboxes to set the character set.
  5. For a passphrase instead of a random string, use the passphrase option — memorable hyphenated words rather than random characters.
  6. Click Regenerate to roll a new password with the current settings, or Copy to copy it to your clipboard.
  7. Check the entropy readout and strength bar, then paste the password where you need it.

Who it helps

  • Everyday users creating new accounts who want a unique, strong password per site instead of reusing one.
  • Admins and IT staff who need to set temporary credentials or reset user passwords quickly.
  • Curious readers learning what password strength actually means, via the live entropy readout.

Limitations

  • It generates passwords; it does not store them. Nothing is saved — you are responsible for copying the password into a password manager or another safe place.
  • No breach checking. The tool has no feature that checks whether a password has appeared in a leaked dataset.
  • No sync or autofill. It does not sync across devices or fill passwords into login forms.
  • Entropy is an estimate of randomness, not a guarantee. A high bits figure does not protect a password that is shared, reused, or stored insecurely.

FAQ

Is this password generator free?
Yes — completely free, and no signup or email is required.

Are my generated passwords sent to a server?
No. The tool generates passwords locally in your browser using crypto.getRandomValues(), and states on the page that generation is 100% client-side.

What does the entropy readout mean?
It is the estimated randomness of the current password, shown in bits (for example, "129 bits · Very Strong"). Longer passwords and larger character sets produce higher entropy.

Can I generate a passphrase instead of a random password?
Yes — the tool also supports memorable hyphenated word passphrases, alongside random character passwords.

How long should my password be?
The tool defaults to 20 characters. Drag the slider to change it; more characters and more character types raise the entropy readout.

Do I need to create an account?
No signup is required at all.

Does it store or remember my passwords?
No — nothing is saved. Copy the password and store it in a password manager yourself.
