What Is the Password Generator Tool?
The Password Generator is a free online utility that helps you create strong, high-entropy passwords instantly, with customizable length and complexity to secure your professional and personal accounts against breaches.
The Password Generator builds passwords by randomly selecting characters from your chosen character sets - uppercase letters, lowercase letters, numbers, and symbols. It uses cryptographically-inspired random selection to ensure uniform distribution. When the exclude similar option is enabled, commonly confused characters like l, 1, I, O, and 0 are removed for readability.

Technical Details
Password generation uses JavaScript's Math.random() for character selection from dynamically built character pools. The character pool is constructed based on user-selected options, and an optional filter removes visually similar characters. All generation occurs client-side with no data transmitted to any server.
