Why a strong password matters

A strong password is your first line of defense against unauthorized access. Weak or reused passwords are the single most common cause of account breaches — attackers use automated tools that can test billions of common passwords per second. A strong password is long (12 characters or more), uses a mix of uppercase and lowercase letters, numbers, and symbols, and is completely unique to each account.

How this generator works

This tool generates passwords entirely inside your browser using crypto.getRandomValues(), the same cryptographically secure random number generator browsers use for encryption. Every character is chosen with true, unbiased randomness — never the predictable Math.random(). Nothing you generate is ever sent over the network, stored, or logged. Your password exists only on your screen, and disappears the moment you close the page.

Managing your passwords safely

The safest approach is to use a unique, randomly generated password for every account and store them in a reputable password manager (such as Bitwarden, 1Password, or your browser's built-in manager). That way you only ever need to remember one strong master password, and the manager handles the rest. Wherever possible, also turn on two-factor authentication (2FA) for an extra layer of protection.

Frequently Asked Questions

What is a strong password?

A strong password is long (at least 12–16 characters), unpredictable, and mixes uppercase letters, lowercase letters, numbers, and symbols. It contains no dictionary words, names, or personal information, and it is used for only one account.

How long should my password be?

Aim for at least 16 characters. Length is the single biggest factor in password strength — every additional character multiplies the number of combinations an attacker must try. For your most sensitive accounts, 20+ characters is even better.

Can I use special characters?

Yes, and you should. Symbols dramatically expand the pool of possible characters, making passwords far harder to crack. If a particular site rejects certain symbols, uncheck the Symbols box or use the Advanced Options to exclude ambiguous characters.

Is this password generator safe?

Yes. Everything happens locally in your browser using JavaScript. No password is ever transmitted to a server, saved, or logged. You can even disconnect from the internet and the generator will still work.

How are passwords generated?

Passwords are created using crypto.getRandomValues(), a cryptographically secure random number generator built into your browser. This ensures each character is truly random and unpredictable — unlike ordinary pseudo-random functions.
