This so much. And you can probably dont even remember which services they are bound to. The service now probably sends "you" a SMS and the people realize they have access to something they should not have to. Just crazy IMO.

I rant about this for a while now, and many people say stuff like "you can just take your phone number with you". Its on par for me with "I have nothing to hide, why would i worry". Its just short sight and projecting personal use on the world.
