Password Generator

WEB

Create strong, random passwords with full control over length and characters.

Weak

What is the Password Generator tool?

This free password generator creates strong, random passwords directly on your device — generation is fully client-side, so nothing you generate ever leaves your browser. Drag the length slider anywhere from 6 to 40 characters, toggle uppercase letters, lowercase letters, numbers and symbols, and a new random password appears instantly with a live strength meter that rates it from weak to very strong. Every password is drawn from your browser's cryptographically secure random source (the Web Crypto API), not a predictable formula — so not even Carbide could guess what you get.

Most password generators at the top of search results belong to password-manager companies, and their free tool is really a doorway to a subscription. Carbide's secure password generator has no upsell, no sign-up and no account: set your options, copy the password in one tap and paste it wherever you need it — a new email account, online banking, a Wi-Fi network or an API key. Ambiguous characters such as I, l, O, 0 and 1 are deliberately left out of the pool, so a password you have to type by hand or read out loud stays unmistakable.

Because everything runs in your browser, the generator works on your phone as easily as on a desktop, and the same tool ships inside the Carbide app for Android and iOS (coming soon), where it works fully offline. Generate as many random passwords as you like — it is free, with no limits and no logging.

How to use the Password Generator

  1. Drag the length slider to the size you need — the range is 6 to 40 characters, and 16 or more is a good default.
  2. Toggle the character sets to include: uppercase (A–Z), lowercase (a–z), numbers and symbols.
  3. A new random password appears instantly, and the strength meter rates it from weak to very strong.
  4. Not happy with it? Tap the refresh button to generate another password with the same settings.
  5. Tap copy to grab the password in one tap, then paste it into the sign-up form or your password manager.

Frequently asked questions

Is an online password generator safe to use?

It is safe when generation happens on your device — which is exactly how this one works. The password is produced in your browser with the Web Crypto API and displayed only in your tab; it is never transmitted, logged or stored. You can even load the page, go offline, and it still generates.

What makes a password strong?

Three things: length, character variety and true randomness. A 16-character password drawn randomly from uppercase, lowercase, numbers and symbols is far stronger than a longer phrase built from names or dates. The strength meter here reflects both the length and how many character sets you enabled.

How long should a password be?

Use at least 16 characters for everyday accounts and 20 or more for critical ones like your main email or banking. Every extra character multiplies the work an attacker has to do, so when in doubt, go longer.

How is this different from the 1Password, LastPass or Avast generators?

The passwords are comparable — all reputable generators use a cryptographically secure source. The difference is the page around it: those tools are lead-ins to a paid password manager, while Carbide's generator is a free standalone tool with no sign-up and no upsell. Storing your passwords in a manager you trust is still a good idea.

Does Carbide see or store the passwords I generate?

No. Generation is entirely client-side: the password exists only in your browser tab until you copy it. There is no server call, no analytics on the value and no clipboard sync.

Is it free, and is there a limit?

Completely free, with no account and no daily cap. Generate one password or a hundred — nothing is counted or stored.

Can I generate a numeric PIN instead of a password?

Yes. Turn off every character set except numbers and set the length to whatever your PIN needs. Note the digit pool skips 0 and 1 to avoid look-alike characters.
