Password Generator

Free Secure Password Generator

Reusing passwords or choosing predictable ones like "password123" is one of the fastest ways to lose control of your accounts. Every service you sign up for should have its own unique, random password — but creating dozens of strong passwords by hand is impractical. Our free password generator creates cryptographically random passwords instantly, with full control over length and character types.

The generator uses the browser's built-in crypto.getRandomValues() API — the same cryptographically secure source used by operating systems and password managers. Adjust the length slider from 4 to 128 characters, toggle uppercase, lowercase, numbers, and symbols, then click Regenerate until you are satisfied. Copy the result with one click. Generated passwords are never sent to any server, making this one of the safest ways to create credentials for new accounts.

Unlike human-created passwords that follow predictable patterns — names, dates, keyboard walks — machine-generated passwords have no bias toward dictionary words or common substitutions. Each character is selected independently from your chosen character set, maximizing entropy and minimizing the risk of successful brute-force or dictionary attacks against your accounts.

How to Use the Password Generator

Set your desired password length using the slider — 16 characters is a good default for most accounts. Check or uncheck character type options: uppercase letters, lowercase letters, numbers, and symbols. At least one type must be enabled. A password is generated automatically when you load the page. Click Regenerate to create a new random password with your current settings. Click Copy to copy it to your clipboard, then paste it into your password manager or account signup form immediately.

Who Uses a Password Generator?

• Everyday users create unique passwords for new online accounts, subscriptions, and apps.
• IT professionals generate temporary credentials for new employees or service accounts.
• Developers create test credentials, API keys placeholders, and demo account passwords.
• Small business owners set strong Wi-Fi passwords and admin credentials for office equipment.
• Students learn about secure randomness and password best practices.
• Privacy advocates avoid patterns and dictionary words that attackers exploit.

• Password length guidance for Wi-Fi, banking, and everyday accounts
• No account, no limits, and no server storage

Password Length and Entropy

Every additional character in a password multiplies the total possible combinations. A 12-character password using all four character types has roughly 94^12 possible combinations — trillions of times more than an 8-character lowercase-only password. The length slider supports up to 128 characters for maximum-security use cases like encryption keys and master passwords. For Wi-Fi passwords, many routers accept 63 characters — use the slider to generate a long, random WPA2 passphrase.

Password Security Tips

Use at least 16 characters for high-security accounts like email and banking. Enable all four character types when the service allows it. Never reuse passwords across different sites — credential stuffing attacks try leaked passwords on every major platform. Store generated passwords in a reputable password manager such as Bitwarden, 1Password, or KeePass rather than writing them down. Enable two-factor authentication wherever possible. After generating a password, copy it immediately — regenerating creates a new one and the previous value is lost. Test your new password with our Password Strength Checker before saving it to your manager.
