---++ What?
Use Facebook as 3rd party application for registering a new user or logging into ODS DataSpace as already registered ODS User which account is associated with a given Facebook account.

* Configure as ODS Administrator in Site Settings->Login Authentication Keys the Facebook API to use the generate from above Client ID
When the above is done, you can perform the following activities in ODS:
* Register in ODS using your Facebook credentials, or:
* For a regular ODS user, for ex. with name XXX you can add in Profile->Personal->Online Accounts your Facebook account, which then will enable you to log in in your ODS XXX user dataspace using the Facebook account credentials.
