WP GDPR Compliance and Social Login

I use a plugin called Social Login, to let users login by using one of their social media accounts, for example Facebook, Google+, Instagram.
But when they login and post with this, they do not use their email adresse. So when they fill in their email adress to get the data that is kept on our website, they don’t see any data, because the plugin can’t find any data with that email adresse. Can this plugin be made compatible with Social Login?
