The very basic libraries responsible for accounts and sso are from upstream project Accounts&SSO (grown out of N9/Meego), is generic and allows adding new kind of accounts: https://code.google.com/p/accounts-sso/
This is handled in Mer project for Sailfish OS.
The framework doing the google/facebook connections for messaging and presence is Telepathy (grown out of Maemo), it's also very generic and allows adding support new kinds of protocols: http://telepathy.freedesktop.org/wiki/
This is handled in Nemo project for Sailfish OS.
So that part is open source.
But for a fully native working support you still would need some additions in the Accounts UI/Settings UI, but that part is not open source and Jolla does (currently?) not allow any additions there (see: https://harbour.jolla.com/faq) and so it's no where documented, how to do it.
