I'm with Arm on this one. Knowing character names, templates, where houses were located... even real life names and addresses are far too easy to know about accounts that aren't your own. Requiring information that isn't available in game or easily found with a quick google search is the only real kind of safeguard to accounts.... even old ones. I have friends that haven't played in over a decade.... I could still tell you the characters names, the templates, names, addresses, phone numbers, birthdates... but that information should never make it where I can access or take ownership of their accounts.
