How do I get accounts in the first place.

Hey.

I'm interested in getting involved with auto buyers, however what I'm currently struggling with is getting accounts in the first place.
This probably is a pretty noob question, but it would be great if you could tell me how I can create/ get accounts.

Thank you in advance.

Buy the game. Thats your account. Using origin id and passowrd
If you on PS4 (and I think xbox too) You can create multiple accounts from a single copy this is why people have many accounts usually as there accounts are not linked to the physical game
