In the future there will be an integration with the most popular public authentication providers. Please see the feature request in PITS
Under the feature request there is a solution from a client. However this scenario is not tested and supported from Sitefinity.
I also found a forum
that might be useful in your case. Please review it.
I hope that my answer was informative enough, should you have any other inquires or problems, do not hesitate to contact me.
