While looking through my SDB this morning, I found this at the bottom of the page
Need some extra security?
Add a PIN Number for use in this area!
The page leads to a coming soon thing, but wow. What a way to protect your items. If you could have your own PIN incase someone does infact get into your account, they'd need that to get anything from your SDB, maybe even your bank too. Although I could see how it could get annoying at the same time.
