Generate strong cryptographically secure random passwords up to 128 characters. Choose uppercase, lowercase, numbers and symbols. Nothing stored or transmitted.
About Password Generator
Generate unguessable passwords using your browser's Web Crypto API (crypto.getRandomValues()), which produces cryptographically secure random values that are impossible to predict. Choose password length from 4 to 128 characters, and toggle character sets including uppercase letters, lowercase letters, numbers, and symbols. Nothing is ever transmitted or stored anywhere — generation is 100% local in your browser.
Frequently Asked Questions
Are generated passwords stored anywhere?
Never. Generation runs 100% locally in your browser using Web Crypto API. Nothing is transmitted.
How long should a password be?
Use at least 16 characters for most accounts and 24+ characters for critical accounts like banking and email.
What makes this generator secure?
It uses window.crypto.getRandomValues() — the same cryptographic random number generator used by security software.
Should I use the same password for multiple sites?
No — use a unique password for every account. Consider a password manager to store them securely.
