Dont think I been on this site since 2013 not even touched a game engine, divorce is a cruel enemy

so before I start researching does blizzard have inbuilt anti cheat or is it just another host like steam only got one account do not want to loose my main.

does it require hardware spoofing and/or two step authentication on some games

I am looking to play about with COD warzone, got a lot of catching up after 7 years away though
I will do an offline probe to start with but any info will help
