Users who choose to login with a social provider(google, facebook, etc) should “just work” as long as they use the same email for the social provider as they did for the main site i.e www.atheistrepublic.com .
Users who would rather use a username and password will need to go through the “I forgot my password” process to create a password.
I had to Google “social provider” and “SSO” because I have no ideas what they mean. And even after Googling and reading what they are, I am just as lost.
Can someone please translate this into language I can comprehend?
