You log on to the beta forums and they be information how to download the client you use your SE account that have legacy and log in to beta very simple. When it came to FFXIV 1.0 alpha/beta they send you a code KBFS,ID46 you know what i mean the normal thing.

this time it just flag your account into beta/alpha very simple and much better this time people can't sell the code without selling there own FFXIV account i know people did that for beta,alpha and people pay for it lol i guess this beta is more worth it huh lol.
