Create cryptographically secure passwords with entropy calculation, pattern analysis, and strength visualization. Multiple types, bulk generation, and advanced customization options.
Start Generating NowOur generator uses cryptographically secure randomness, calculates real entropy values, detects weak patterns, and offers 8 different password types including military-grade options. Most free generators use basic Math.random() which is predictable.
Never. All password generation happens entirely in your browser using client-side JavaScript. Passwords are never sent to our servers, logged, or stored anywhere. Even session history is stored locally.
