How long should my password be?

We recommend at least 16 characters for most accounts, and 20+ for sensitive accounts like email and banking. Alternatively, a memorable passphrase of 5-6 random words provides excellent security that is also easy to remember.

What is a memorable password or passphrase?

A passphrase uses 4–6 random, unrelated dictionary words joined by a separator — for example: apple-tunnel-river-grape. A 5-word passphrase can have more entropy than a complex 12-character random password, while being far easier to remember.

What is two-factor authentication and do I still need it?

2FA adds a second verification step — usually a time-based code from an authenticator app — on top of your password. Even if your password is compromised, 2FA prevents unauthorized access. Always enable 2FA on important accounts alongside using a strong password.

Generate Instantly

Our tool uses your browser's built-in cryptographic engine (crypto.getRandomValues) to create a truly unpredictable password in milliseconds. No server involved.

Copy & Store Safely

Click Copy, paste it where you need it, and save it in a free password manager like Bitwarden. Never reuse a password — use a unique one for every account.

Everything You Need

Built with the best ideas from the world's top password generators — and then improved.

3 Password Modes

Random characters, memorable passphrases, or numeric PINs — the right type for every use case, from banking to Wi-Fi.

Cryptographic Security

Uses crypto.getRandomValues — the Web Crypto API standard used by browsers and security professionals worldwide.

100% Client-Side

Every password is generated entirely in your browser. No data sent to any server — ever. Works fully offline once loaded.

Entropy Strength Meter

See your password's exact strength in bits of entropy — not just a vague label. Know precisely how secure your password is.

Batch Generation

Generate 5, 10, or 20 unique passwords at once — perfect for setting up multiple new accounts or a team onboarding.

Zero Account Required

No email, no password, no tracking. Open the page and start generating immediately. No friction. No upsell.

Why Client-Side Generation Matters

Every password is created entirely in your browser using the Web Cryptography API. This isn't marketing — it's verifiable. Open DevTools → Network while generating: you'll see zero network requests.

Frequently Asked Questions

Everything you need to know about secure passwords and how this tool works.

Is this password generator completely free?

Yes — 100% free forever. No signup, no login, no credit card, no premium tier. Every single feature is available to everyone, always, at no cost.

Are my passwords stored or sent anywhere?

Absolutely not. All generation happens inside your browser using the Web Cryptography API. Passwords are never transmitted to any server, never stored, never logged. You can verify this yourself: open DevTools → Network tab and generate a password — you'll see zero outbound requests.

How long should a strong password be?

We recommend a minimum of 16 characters for most accounts. For highly sensitive accounts like email, banking, or work systems, use 20+ characters. As an alternative, a memorable passphrase of 5–6 random words provides excellent security while being far easier to type and remember.

What is a memorable password (passphrase)?

A passphrase uses 4–6 random, unrelated dictionary words joined by a separator — for example: apple-tunnel-river-grape. These are surprisingly secure: a 5-word passphrase from a large word list has more entropy than a complex random 12-character password, while being far easier to remember and type. This approach is recommended by NIST (National Institute of Standards and Technology).

What is password entropy and why does it matter?

Entropy measures how unpredictable a password is, expressed in bits — calculated as log₂(pool_size^length). The higher the entropy, the harder it is to crack. A password with 60+ bits of entropy is considered strong for most purposes; 80+ bits is very strong. Our tool displays entropy in bits alongside the strength label so you know exactly how secure your password is.

Should I use a password manager?

Yes, strongly recommended. Since strong passwords are impossible to memorize, a password manager stores them securely — you only need to remember one strong master password. We recommend Bitwarden (free and open-source). Use this generator to create strong passwords, then save them in your password manager.

What are "ambiguous characters" and should I avoid them?

Ambiguous characters look similar in many fonts: 0 (zero) vs O (capital O), 1 (one) vs l (lowercase L) vs I (capital i). If you need to type your password manually — such as on a TV, gaming console, or mobile keyboard — enable "Avoid Ambiguous" to exclude these characters. If you're using copy-paste, leave it off for maximum entropy.

What is two-factor authentication (2FA) and do I need it?

2FA adds a second verification step — usually a time-based code from an authenticator app like Google Authenticator or Authy — on top of your password. Even if your password is leaked in a data breach, 2FA prevents attackers from accessing your account. Yes, you absolutely need it. Use both: a strong password AND 2FA on every important account.
