Secure Password Generator

Generate strong, random passwords with a live strength estimate.

Generators Runs in your browser

Are the generated passwords secure?

Yes — NMSnabbit generates passwords with crypto.getRandomValues, the browser cryptographically secure random source (not the predictable Math.random). You choose the length and character sets and see a live, entropy-based strength estimate, and every password is created locally in your browser and never sent anywhere.

How to use the Password Generator

1 Set the password length with the slider.
2 Choose which character types to include: lowercase, uppercase, digits, symbols.
3 Optionally exclude ambiguous characters like l, 1, O and 0.
4 Click Generate, check the strength meter, and copy your password.

What you can use it for

Creating unique passwords for new accounts.
Generating API keys or secrets for testing.
Replacing weak, reused passwords.
Producing PINs or codes with custom character sets.

Frequently asked questions

Are the passwords truly random?

Yes. Passwords use crypto.getRandomValues(), the browser cryptographically secure random number generator — not the predictable Math.random().

Is my password sent over the internet?

Never. Generation is 100% local to your browser, so the password is only ever seen by you.

What does the strength meter mean?

It estimates entropy in bits from the length and character set. More bits means harder to guess; aim for “Strong” or “Very strong”.

Why exclude ambiguous characters?

Characters like l, 1, I, O and 0 are easy to confuse when reading or typing a password. Excluding them makes passwords easier to use.
