I just want to mention a few things about the problem you might experience with our auto updates process.
When you send feedback with valid username and password we save an authentication token and next time we use that instead of username/password. We do that, because we don't want to compromise your password security (safe the password on your machine). If you have that token we don't show the password textbox and we try to authenticate you with the token. The problem is that after a while the token expires and becomes invalid for the service that downloads the file. The solution for that is already mentioned by Tommy Tucker (thank you for that).
What we will do is to improve JustCode to check first if the token is valid before trying to use it (hiding the password textbox).
