I would like to use a Cognito User Pool for Facebook logins only, which may be possible using the built in login form, but I need to use my own.
Theoretically, when it comes to a custom form, it shouldn't be hard: after I receive a user object from FB, I bind the user and email attributes to the ones in my User Pool and I save it.
But what to do about the password field and future authentication? And here I have failed during my journey...
...
userPool.signUp('FoobarUser', '**password?**', attributeList, null, function(err, result){
...
While digging deeper into the docs, I tried to implement a Identity Pool (Federated Identities), managed to save user info in the form of datasets as well, but then I realised, querying these sets gonna be a huge pain if possible at all.
Maybe I'm failing to understand the concepts, I would be really thankful if someone could suggest a way to manage facebook logins in a nicely organised fashion using Cognito.
