String[,] that can be changebale

Question

I have a sistem of accounts that works on String[,]
String[,] accnts={{"User1","pass123"},{"user2","pass234"}}
and I want to make a code that can edit this string with console.readline and then save this so when I will open the app the string will be with my changes.
open app- I am writing user1 change pass then I wrote something like password321 and closing the app when I return to the app the pass will be password321 and not pass123
