thewhiteninja/mobile_bypass ? reverse-engineered prompt

Build me a browser extension that generates a MobilePass token and can automatically fill it into the right input field on a webpage.

I want it to feel simple for a normal person to use, with a small popup or button where they can enter whatever secret or setup info is needed, then generate the token and paste it into the page for them. It should work in the browser as a Chrome and Firefox extension, and it should handle the token generation securely and reliably.

Please make the extension easy to install and use, with a clean interface and sensible defaults. If you need to check current browser extension docs or token generation details online, go ahead and look them up. Also make sure it can detect the input field on the page and fill it in without the user having to copy and paste manually.
