Are my generated passwords sent to any server?

Never. The generator executes 100% on the client side in JavaScript. The password is generated in your browser's local memory and is immediately wiped when you close or refresh the tab.

What makes a password strong against brute force attacks?

Password strength is determined by character entropy and length. A 16-character password combining uppercase, lowercase, numbers, and symbols produces over 95 bits of entropy, requiring billions of years for modern supercomputers to brute force.

Can I exclude confusing characters like 0, O, 1, and l?

Yes. You can toggle the 'Exclude ambiguous' option to ensure easy visual readability when typing passwords on physical devices.
