I don't actually know, but I guess we should assume that it is. I don't see why you would anyway, unless it's a member of your family like your brother. My advice? Assume that it is, and don't do it, not because it's against the rules, but because it's a pretty easy way to get all your stuff stolen, and possibly even your account.
"Strive for balance of all things. When the scales tip to one side or the other, someone or somethings gets short-changed. When someone gets short-changed, unpredictability and strife unbalance the world around us...To achieve freedom from greed, from want, and from strife, all parties in any exchange MUST find balance." -House Hlaalu's Philosophy of Trade

O, be some other name!
What's in a name?
That which we call a rose?
By any other name would smell as sweet.

@d0e1ow: There is no singular thing within a game's little ecosystem that will convince you that you hate the game, hate your life, and hate everyone around you faster than the game's official forums will.
@TaffyIX: Life is too short to get upset by a video game.
I'd be interested in knowing the exact rules of this as well, but only in the case of a spouse. To be honest I dislike keeping any passwords from him for any account. Games are no exception. I always wondered if its against TOS if a spouse tries a game out. I've always sought and received permissions from other games but have never bothered with ESO since he disliked beta
