Personally I won’t recommend to use the “Edit Scores Password” option and instead do a quick review of all edited scores when finalizing match results. See the shooter filtering options in the Android app.
@Mike_S you are mixing up two somewhat independent features: the RO tracking and the scores editing password.
The latter option is only available when “Secure Match” option is enabled in the match settings and the “Match Password” is set. Please note that the “Edit Scores Password” will have to be entered for any scores corrections, including reassigning scores.
I do recommend to enable a self-served RO tracking, so you will have some track record of who entered or edited scores (you’d have to trust your shooters and ROs).
