Account checker

Hi guys,
I'm looking for a program that i can input a list of Minecraft accounts into and check if they work. I have a list of accounts in the format Name:Password. Does anyone have something that i can do this with?

ive made one like this and it works,but i dont know how to use proxies so you get ipblocked from using anything minecraft related for a day

everything has to be coded.

if you want to help me do it,go to your chrome settings -> proxy settings and get it to work,if it works ill make the damn thing

nowhere,i cant make it without proxy settings

yea,press lan setting and get this thing to work! good luck,im failing horribly

u use the checkbox for using proxy settings and u use an adress,but remember i didnt succeed
