Right now, we don't have any way to allow for authentication in the admin area using social networks. There are various reasons for why we haven't implemented this both from a technical (the admin area is very different from the front-end area) to business (we get a request for this feature about 1 time per year).
If you're concerned about security in the admin area, we'd recommend using the 2-step authentication features built-in to Joomla already. You can use Google Authenticator, YubiKey and multiple other systems. Our SCLogin module also works with 2-factor authentication on the front-end, when it's enabled, making it an easy option.
I hope that helps answer your question, but if you need more assistance or have other feedback, please let me know.
Thanks,
Alex
