I know this might be an obvious question, but its escaping me. When logging on websites, I have seen check boxes for things like "i'm using a public device" and "Keep me signed in".
I know keep me signed in would be the traditional login function which would be meant to keep the user always logged in. But I'm stuck on the "I'm using a public device" feature, what does it actually to do? Does it just limit the length of the login period?
I don't use session logins, I use a tokenized cookie with 24 hour expiration that is matched up in a database table to the user and subsequently their shopping cart.
