Facebook Connect with multiple FB accounts

Question

Hi Friends,

I am developing a business site with Facebook Connect enabled and its working fine for me. Now, I came across a situation where I have a user with 2 or more FB accounts and 1 of them is registered with our site.

For example

[email protected] (Registered on Facebook and using FB connect on our site) [email protected] (Registered on Facebook but not in our site)

With above email addresses, when a user logs in with [email protected] on Facebook he gets logged in, in our site as well. But on the other side when a user logs in on Facebook with [email protected] and same time logs in on our system with [email protected] (without using FB connect).

Here I see a session conflict and trying to solve it. I hope you people will share your thoughts to help me out.

Regards

Answer 1

At my site ours users could use

1. our site's account
2. a FB account
3. a FB account merged with our site's account (based on email).

so if someone owns more than one FB account, only the one with matching email would be merged. If someone tries to log with a FB account and that account's email is not registered within our application, a new account in our site is created.
