If your login name doesn't come up by default when you go to log in to Connect this needs to be set first
On opening Connect the account name should be filled automatically.
If it isn't or it's filling with the wrong details please follow the following steps;
While logged into connect, go to "Filemaker Pro" then "Preferences"
1. Make sure you're on the "General" tab
2. Select "Other" and then fill in your full user name
3. Click ok
This will set the system to automatically pull in your user name the next time you go to log in
