Passwords are generated using the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers directly from your operating system's entropy source. This ensures each password is truly random and unpredictable, unlike Math.random() which uses a predictable algorithm. The generated passwords meet the highest security standards.
For strong security, use at least 16 characters combining uppercase, lowercase, numbers, and symbols. For highly sensitive accounts like banking or admin access, 20+ characters is recommended. Each additional character exponentially increases the number of possible combinations, making brute-force attacks impractical even with modern hardware.
No, passwords are generated entirely in your browser using client-side JavaScript and are never stored, logged, or transmitted to any server. The generation happens locally on your device with no network requests involved. Once you close or refresh the page, the generated passwords exist only where you copied them.
