Weak passwords are still the easiest way into your accounts. Our free strong password generator creates long, random, genuinely unpredictable passwords in a single click. Choose the length and character types, uppercase, lowercase, numbers, and symbols, and the tool above builds a password so complex it would take centuries to crack by brute force. A 16-character random password has more possible combinations than there are stars in the observable universe, that mathematical reality is what keeps you safe, not clever substitutions like “P@ssw0rd”.
It’s completely free with no sign-up, and every password is generated 100% in your browser using your device’s secure random number generator. Nothing is ever sent over the internet, stored, or logged, we couldn’t see your passwords even if we wanted to. Use a unique password for every account, keep them in a password manager, and check out our QR code generator for sharing Wi-Fi access safely, or browse all free tools in the Savozi collection.
