how to use it it ask user name and password

please update it so it will work with 0.13.x all modes spotted when i update my game
and i look in the the modes files and i think if you just copy the code and made for copper ore it will be useful

so if i update the game to 0.13.x i will loss all modes so far , but what will do with that when they asked me for username and password to update modes ?
or i have to keep my game out dated in order to play with some cool modes ?
