Passwords are generated with crypto.getRandomValues entirely in your browser — nothing is sent to a server or stored.
Generate strong, random passwords online, free. A password generator creates unpredictable passwords from a chosen length and character set. This tool draws every character from the browser's cryptographically secure random source (Web Crypto's crypto.getRandomValues), not Math.random, so the output is suitable for real accounts — and it never leaves your device.
Each password is generated with cryptographically secure randomness and an entropy estimate, so you can see how strong it actually is. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Characters come from crypto.getRandomValues (CSPRNG), the standard browser source for security-grade randomness — far stronger than Math.random.
Choose length and which character sets to include (uppercase, lowercase, digits, symbols) to meet any password policy.
See an estimated bit-strength so you can target the 60–80+ bits that resist brute-force attacks.
Passwords are generated locally and never sent anywhere — nothing is logged, stored, or transmitted.
Yes. They are generated with the browser's cryptographically secure random number generator (crypto.getRandomValues) and never leave your device, so they are safe for real accounts.
Length matters more than complexity. Aim for at least 16 characters; with a full character set that is roughly 100+ bits of entropy, which is infeasible to brute-force. NIST SP 800-63B recommends long passwords and discourages forced complexity rules.
No. Generation happens entirely in your browser using JavaScript. We don't upload, log, or store anything you generate.
Entropy (in bits) estimates how unpredictable the password is. Each extra bit doubles the guessing effort; 60+ bits is strong for most accounts and 80+ bits is very strong.
Yes. Generate a unique strong password here and store it in a reputable password manager so you don't have to remember or reuse it.
