Have you logged on your steam account and you had 2-Step Authentication on and thought "what if i use the 2-Step Authentication codes as usernames?" Welp, now you have the idea.. Now make a account on roblox or something. idk. don't ask. i bet no one on roblox use steam. if they do. idk. (and authentication codes expire so people cant hax in to your acc) (i have no responsability for the loss of steam account, i promise.) (pls no ban off devinity)
Using the two step authentication codes as usernames... what would that accomplish, you might as well find a random letters generator online and use that instead.
