About This Tool

Password Generator creates cryptographically secure random passwords using your browser's built-in crypto API. Customize length (8-128 characters) and character types (uppercase, lowercase, numbers, symbols). The strength meter evaluates password entropy and gives a clear rating from Weak to Very Strong. Everything runs locally — generated passwords are never sent anywhere.
