Why do devices like Appletvs have no "unmask password" option when you are signing them in?

I mean the thing is in my house, who exactly is going to be shoulder surfing me and stealing my itunes login in my living room?

Not to mention after 2-3 tries it locks the itunes account, that opens a whole 'nother can of worms when the client has to create a new password and re-sign in every device on that account.
