What happens if you've created your account on lots of websites using Facebook Connect, and then one day you decide to completely delete your Facebook account?
I don't mean created a unique account on the site then linked your FBC (and Twitter, etc) to it, I mean actually created the account by registering on the site through FBC.
Do you lose all your accounts on the other websites too, or do they somehow remain even though you didn't create a unique userid, pwd, email for the account on those sites?
If you run a site that uses Facebook for login, when you log someone in via Facebook, you can ask for their email address via the "email" extended permission. Your site can then support a password reset page (like most sites already do) to enable those users to create a password via email if they decide to delete their Facebook account. Requesting email address is a good "escape valve" for users if you are concerned about this aspect of Facebook login.
FB Connect has a reclamation process or something to deal with this (theoretically), but the website has to support it.
As someone using FB Connect, we don't support it, and I'm guessing most small/medium sites (like mine) don't either. It's such an edge case that most people that fall in that bucket are SOL.
