About Strong Password Generator

Generate cryptographically secure passwords using window.crypto.getRandomValues(). Customize length (8-128 chars), character sets. Generate up to 10 passwords. Nothing sent to any server.

Weak or reused passwords remain one of the leading causes of account compromise — credential-stuffing attacks work specifically because people reuse the same password across multiple sites, so one breach can cascade into many. A genuinely strong password needs sufficient length (12+ characters is the current baseline recommendation) and true randomness, which is why this tool uses the browser's built-in `window.crypto.getRandomValues()` API rather than a simple pseudo-random function — it's the same cryptographically secure randomness source used for encryption keys, not a predictable algorithm. You can customize length and which character sets (uppercase, lowercase, numbers, symbols) to include, and since generation happens entirely in your browser, the password is never transmitted anywhere.
