Secure Password Generator
Generate strong, random passwords using your browser's cryptographic API. Customize length and character types. Nothing leaves your device.
Why use a random password generator?
Humans are bad at creating random passwords. We tend to use patterns, dictionary words, and personal info that attackers can guess. A cryptographic generator creates truly unpredictable passwords that resist brute-force and dictionary attacks.
Frequently Asked Questions
What makes a strong password?
A strong password is at least 16 characters long and includes a mix of uppercase letters, lowercase letters, numbers, and special symbols. It should not contain dictionary words, personal information, or common patterns like '123456' or 'password'.
How does this password generator work?
This tool uses your browser's built-in cryptographic random number generator (crypto.getRandomValues) to create truly random passwords. This is the same method used by professional password managers like 1Password and Bitwarden.
Is the generated password stored anywhere?
No. The password is generated entirely in your browser using client-side JavaScript. It's never sent to any server, logged, or stored. Once you close or refresh the page, the generated password exists only where you've copied it.
How long should my password be?
Security experts recommend at least 16 characters for important accounts. For maximum security (e.g., master passwords, encryption keys), use 20-32 characters. Longer passwords are exponentially harder to crack.
