Is this password generator secure and private?

Yes. Every password is generated locally in your browser using the cryptographically secure crypto.getRandomValues API. Nothing is ever sent to a server, logged, or stored — close the tab and the password is gone.

What makes a strong password?

A strong password is long (16+ characters), unpredictable, and mixes uppercase letters, lowercase letters, numbers, and symbols. Randomly generated passwords are far stronger than anything a person invents because they contain no guessable patterns or personal information.

How long should a password be?

Aim for at least 12 characters, and 16 or more for important accounts. Length is the single biggest factor in resisting brute-force attacks — each extra character multiplies the number of possible combinations dramatically.

What does "exclude ambiguous characters" do?

When enabled, it removes characters that are easy to confuse when read or typed manually — such as the letter l, capital I, the number 1, capital O, and the number 0. This makes passwords easier to transcribe correctly without meaningfully reducing their strength.

Can I trust a browser-based password generator?

Yes, when it runs entirely client-side like this one. Because generation happens in your own browser with the Web Crypto API and no network requests are made, there is no server that could ever see your password. You can even disconnect from the internet and it will still work.

Password Tips

Stay safe with these password best practices.

Use a unique password per site

Never reuse passwords. If one account is breached, unique passwords keep the rest of your accounts safe.

Longer beats complex-but-short

A long password is exponentially harder to crack. Favor length over hard-to-remember complexity in a short string.

Use a password manager

A password manager securely stores every generated password so you only have to remember one master password.

Avoid personal info

Don't build passwords from names, birthdays, or common words. Random characters have no guessable patterns.
