有办法找到通过Facebook认证的用户吗？

[Philip_Colmer]

我们计划在 Discourse 站点上停用 Facebook 登录功能。在实施之前，我想先查明是否已有用户通过该方式登录，以便联系他们切换至其他登录方式。

请问如何查找这些用户？

Find all users who used "login with facebook"

for reasons we want to discontinue that and would like to know the impact it would have on our user base. is there an easy way to find that out?
