Can’t log in from inside app

I am setting up my first match. Building match on an iPad and will score on a pair of Kindle Fires. When I hit “new match” it asked me to log into Practiscore. My username and password failed. However, I was able to build the stages and download the competitors and squads via the PIN. I want to post to Practiscore website after the match. Will it still work without this log in?

You don’t need to be logged in to run a match or post results.
Take a look at this tutorial if you haven’t already.
