Password Generator

Generates random passwords using your browser's built-in cryptographic random number generator — the same kind used for encryption, not a weaker "math random". Nothing is sent anywhere, ever.

Frequently asked questions

Is this password generator secure?

Yes. It uses your browser's built-in crypto.getRandomValues() function, which is a cryptographically secure pseudorandom number generator. No password is ever sent to a server.

Can I use these passwords for banking?

Yes, the passwords are generated with high entropy and are suitable for any account. We recommend using a password manager to store them securely.

How long should my password be?

At least 16 characters for maximum security. Our generator defaults to 20 characters with a mix of uppercase, lowercase, numbers and symbols.

Does this tool store my passwords?

No. Everything happens in your browser. The generated password is never transmitted, logged, or stored anywhere.

What's the difference between this and online password generators?

Most online generators send your password to their server to generate it. Ours runs entirely client-side — your password never leaves your device.

Why use a strong password generator?

Human-created passwords are fundamentally weak. Studies show that 80% of data breaches involve stolen or weak passwords, and the most common passwords are still "123456", "password", and "qwerty". Humans are predictable: we use names, birthdays, keyboard patterns, and simple substitutions (like "P@ssw0rd") that cracking algorithms defeat in seconds. A password generator creates truly random strings using cryptographically secure algorithms from your browser — completely unpredictable, unguessable, and unique every time. For banking accounts, email, cloud storage, and corporate systems, a 16+ character password with mixed cases, numbers, and symbols is the minimum standard. Our generator also offers memorable passphrase mode: four random words separated by symbols (like "Horse-Battery-Staple-42") — easy to remember, hard to crack, and often stronger than random characters. Unlike server-based generators, ours runs entirely in your browser. Passwords are never transmitted over the internet, stored in logs, or seen by anyone.
