Can not set the password at first

It seems that I need a current password to set a newer one, but after inputting the password"admin" as it shows.I found it was incorrect. And I can not found anything in the table"ofuser".I want to know what’s the default password or what should I do.

You are running into this issue https://issues.igniterealtime.org/browse/OF-1298
I suggest not to use launcher at all. It already installs the service.
