sorry but offering only Google or Facebook Logins are a no-go.

Try offering classical username/password or - at maximum - a GitHub / GitLab / Bitbucket login, but not Facebook or Google!

I will add github soon....we did have email/password login first ...you can see we have two buttons for login and signup separately..but after some feedback...we decided not to purse that as it saved us some hassle with verificaton emails...thanks for the feedback...
