Guild Wars 2

Is is possible to create a separate shortcut for my second GW2 account. I recently opened a second account (5 chars just isn’t enough) and rather than have to retype the account passwords all the time, is there a way to create a second shortcut with second account password etc saved?

Yes, you can. In a way. You can create a shortcut that automatically logs you in and/or change the current shortcut to log you in. You can do that by adding the command line arguments: -name, -password, -nopatchui.

So you’d end up with a shorcut with a command line looking like:
GW2.EXE -name mail@address.com -password 12345 -nopatchui

AFAIK, there is no way to populate the information on the launcher dialog by using command line arguments. You either have to completely log in using the arguments or by manually entering the information on the launcher dialog.

You might want to check the GW2 wiki page for command line arguments. It should have the information you need, in case I didn’t remember things correctly.
