recently I am learning AWS cognito, and I want to allow users to use their facebook accounts to sign up to my website, and AWS cognito can add this new user to the user pool, so that I don't need to manage separate user directories. Is there any way to do it? I have tried many tutorials but none of them work.
And, I am also looking for how to link the facebook account with an existing account in the user pool, any instructions or sample projects will be helpful. I have been spending a lot of time on these problems, that's so annoying, I'll really appreciate your help.
