Yes/No + more question:
Is it possible to use the Facebook SSO system and simultaneously register a user for your own website/app?
As in requiring just one keypress on the part of the user.
Also, are there working examples of this on iPhone and Android?
From what i've read, there's a process for doing SSO and a separate process for doing registration.
The reasoning is that I'd like to keep my own record of user data in addition to what facebook gives me through the Insights system, BUT i would like to make this as painless as possible.
t;;dr has this been done before, what are some examples, and any useful and relevant documentation available?
