Don't make it too complicated.
Exactly and you guys so far haven't got the gist of a single click idea. I don't want to leave my main PC running all the time just to VNC into it. Which, by the way I could already do. But, even if I did I would still have to go through the loading email client, requesting emails and closing it after memorizing the OTP etc.
I want a small POP3 system that when I double click the icon it
opens/runs
connects to my email ISP-server
downloads only the specific email account emails.
displays the first line of all emails downloaded.
I memorize the OTP
Waits 2-minutes then closes itself.
In that time I have entered the OTP into the feed request and everyone is happy.
It's called automation! By the time I created the OP and now explained this all so far I could have written the thing. I give up.
