Logged-in mode

We have a lot of Qt Account logins especially during the evaluation process. Could we reduce the number of logins?

Installer could check, if the login credentials/access token exist for the user and use that to automatically login before the installation. The UI would show the status: logged in and there would be a button to change the login credentials. 

In the maintenance tool this would be even more useful, as the tool does not login with other credentials, but only those used in the actual installation.
