Strong, unique passwords generated instantly in your browser. Nothing ever leaves your device.
PIN Length
No sign-ups, no servers. Just fast, strong passwords generated right in your browser.
All generation happens in your browser. Your passwords never touch our servers — because we don't have any.
Instantly see how strong your password is with our live entropy meter as you adjust length and character sets.
Describe what you need in plain English and our AI will craft a password that fits your exact requirements.
Understanding the science behind strong credentials helps you make smarter decisions — not just for this tool, but for every account you own.
Over 15 billion stolen credentials are currently circulating in breach databases online. Attackers run automated scripts — called credential stuffing — that test leaked username/password pairs against hundreds of services in seconds. If you reuse a password from any breached site, every other account sharing that password is effectively compromised. A weak or reused password is not just a minor risk; it is an open door.
Length beats complexity every time. A 20-character lowercase passphrase is exponentially harder to crack than an 8-character mix of symbols. What matters most is entropy — the number of possible combinations an attacker must try. Each additional character multiplies the search space. Aim for at least 16 characters; use uppercase, lowercase, digits, and symbols when the site allows them; and never include predictable patterns like your name, birth year, or "123".
A random 16-character string like xK7!mP2#qL9$wR4@ is extremely secure but nearly impossible to memorise. A four-word passphrase like correct-horse-battery-staple is just as strong (over 44 bits of entropy) yet far easier to remember. Use a random password for accounts stored in a password manager, and a passphrase for anything you need to type from memory — like your manager's master password or your device login.
Following these five habits eliminates the vast majority of password-related account takeovers:

Everything you need to know about secure password generation, entropy, passphrases, and more.
Yes. All passwords are generated using the Web Crypto API directly in your browser. No data is ever sent to a server, and the randomness is cryptographically strong.
No. Your AI prompts are sent only to the Cloudflare Workers AI endpoint to generate a response. Nothing is logged or stored on our end.
For most accounts, 16+ characters with a mix of uppercase, lowercase, numbers, and symbols is excellent. For high-value accounts like banking or email, aim for 20+ characters.
Passphrases are longer and easier to remember while still being very secure. Use AI Mode to generate a memorable passphrase tailored to your context.
A random password is a short, dense string of mixed characters (e.g. xK7!mP2#) designed to be stored in a password manager. A passphrase is a sequence of common words (e.g. lamp-cloud-river-stone) that is longer, easier to type, and still carries high entropy. Both are secure when generated properly; the choice depends on whether you need to memorise the credential or rely on a manager.
No — and this is one of the most important rules in password security. When any service suffers a data breach, attackers immediately test the leaked credentials against thousands of other sites automatically. This attack is called credential stuffing. If you reuse a password, a single breach can cascade into dozens of compromised accounts. Use a unique, randomly generated password for every service, and let a password manager handle the storage.
Entropy, measured in bits, quantifies how unpredictable a password is. The higher the entropy, the more guesses an attacker must make to crack it. A random lowercase letter adds about 4.7 bits; adding uppercase, digits, and symbols to a 16-character password can reach 100+ bits — far beyond any current brute-force attack. The strength meter displays an entropy-based score so you can see the real security level of every password you generate.
A PIN (Personal Identification Number) is a short numeric code typically used to unlock a physical device or card rather than an online account. PINs are secure in that context because hardware enforces a limited number of attempts before locking. For online accounts, a PIN alone is too short and too guessable — use a full password or passphrase instead. Use the PIN generator here for device lock screens, bank cards, or any numeric-only scenario.
AI Mode sends your description to a Cloudflare Workers AI endpoint (Meta's Llama model). The AI interprets your request and suggests a password; it is returned to your browser and never logged or stored. Your prompt is ephemeral — Cloudflare does not retain it after the response is sent. If you are concerned about privacy, use Random or Passphrase mode, which generates passwords entirely inside your browser with no network requests.
Browser-saved passwords are convenient but carry real risks: they are accessible to anyone with physical access to your unlocked device and potentially exposed if your browser account is compromised. A dedicated password manager (Bitwarden, 1Password, KeePass) encrypts your vault with a master password only you know. For anything beyond casual accounts, a dedicated manager is strongly recommended.
A password is weak if it is short (under 12 characters), uses predictable patterns (sequential numbers, keyboard walks like "qwerty"), contains personal information (name, birthday, pet), or appears in common password lists. Attackers use dictionary attacks that test millions of known passwords in seconds. A password like "Summer2024!" looks complex but falls immediately because it follows a well-known pattern. Always generate passwords randomly.
Modern security guidance (from NIST and other bodies) has moved away from mandatory periodic changes. Changing on a fixed schedule often leads to weak, predictable variations. Instead, change a password immediately when: you suspect it has been compromised, the service reports a breach, you shared it with someone who no longer needs access, or you detect suspicious login activity.
