Those users who have previously signed up to the discontinued via Facebook sign-up need to establish a FIBA 3x3 username and password to access either web site

When the user signed up via Facebook, the user name set was the email address the user's Facebook account was linked to at that point of time. The password for that username can be reset with the Forgot Password function.

In case this doesn't help, please contact the FIBA 3x3 user support with this form
