Free Online Password Generator
Generate strong, secure passwords instantly — free, private, and entirely in your browser. Our password generator creates cryptographically random passwords using your device's built-in secure random number generator (crypto.getRandomValues), the same technology used in professional security tools. No passwords are ever transmitted to any server — everything happens locally, so your generated passwords remain completely private. Choose your desired length (up to 128 characters) and select from uppercase letters, lowercase letters, numbers, and special symbols to meet any website's requirements. The password strength meter gives you real-time feedback as you customize your settings. Strong passwords are your first line of defense against unauthorized account access — a 16-character random password with mixed character types would take millions of years to crack by brute force. Use the copy button to instantly add the password to your clipboard, then save it in a password manager like Bitwarden, 1Password, or LastPass for secure storage.

FAQ
- Are passwords generated securely?
- Yes — all passwords are generated using crypto.getRandomValues, the Web Cryptography API's secure random number generator. This is the same standard used in professional cryptography tools and is far superior to Math.random(). The randomness comes from your operating system's entropy pool, making it genuinely unpredictable and cryptographically strong.
- Are my passwords stored or sent anywhere?
- No — your passwords are generated entirely within your browser and never leave your device. No data is sent to any server, no passwords are logged, and no analytics capture your generated values. You can even use this tool in airplane mode after the page loads. Once you close or refresh the page, the generated password is gone — which is why you should copy it immediately and save it in a password manager.
- How long should my password be?
- Security experts recommend passwords of at least 16 characters for sensitive accounts like email, banking, and social media. Longer is always better — a 20-character random password is exponentially harder to crack than a 12-character one. For a password you need to memorize, consider a passphrase (4–5 random words) instead. For accounts stored in a password manager, use the maximum length the site allows.
- What makes a password strong?
- A strong password has four key properties: length (16+ characters), randomness (not based on words or patterns), variety (a mix of uppercase, lowercase, numbers, and symbols), and uniqueness (never reused across sites). Our generator handles the first three automatically. The fourth — uniqueness — is why using a password manager to generate and store a different password for every account is the gold standard of password security.
