Enable Oauth Login Using Facebook

OAuth 2.0 is not an authentication protocol. var provider = getProviderForProviderId(providers[0]); // At this point, you should let the user know that he already has an account // but with a different provider, and let him validate the fact he wants to // sign in with this provider. There are at least a few ingredients that must brought together in the right way to make it work, and OAuth can be one of these ingredients (perhaps the main ingredient) but it doesn't have to be involved at all. See the Setting Up Multiple Environments for more information on multiple environments. // If the user has several providers, // the first provider in the list will be the "recommended" provider to use. Access of a protected API as proof of authentication. goToApp(); }); return; } // All the other cases are external providers. For a list of error codes have a look at the Auth Reference Docs. However, mere possession of an access token doesn't tell the client anything on its own. Copy the App ID and App Secret from the Settings of your app on Facebook:. A standard for user authentication using OAuth: OpenID Connect. As far as an OAuth client is concerned, it asked for a token, got a token, and eventually used that token to access some API. However, that's not the only way to get an access token in OAuth. // Sign in to provider. This would allow an attacker to impersonate a user at a naive client by simply swapping out a user identifier in the right call sequence. Once you have the token you can call the API, following Facebook's documentation. For example, sign in the user in a browser as described in the Handle the sign-in flow manually section, but send the access token to your Node.js application instead of using it in the client app. In the Connections > Social section of the Auth0 dashboard a TRY icon will now be displayed next to the Facebook logo:. On the Facebook for Developers site, get the App ID and an App Secret for your app. In a seperate tab or window, go to the Connections > Social section of the Auth0 dashboard. OAuth says absolutely nothing about the user, nor does it say how the user proved their presence or even if they're still there. Auth0 only allows one Facebook connection to be configured per tenant. Refresh tokens and assertions can be used to get access tokens without the user being present, and in some cases access grants can occur without the user having to authenticate at all. You need a recipe that says what to combine and how to combine them, and there are a large number of different recipes that say how that can be accomplished. On the other side of the transaction, OpenID Connect defines a client registration protocol that allows clients to be introduced to new identity providers. This is OK in the regular OAuth world where one authorization server protects a specific API, and the two are closely coupled. It doesn't know anything about who authorized the application or if there was even a user there at all. It is also mitigated by passing the set of authentication information directly to the client during the OAuth process instead of through a secondary mechanism such as an OAuth protected API, preventing a client from having an unknown and untrusted set of information injected later in the process. Click Settings in the left nav. Click TRY. Authentication vs. var credential = error.credential; // . Since it's an open standard, OpenID Connect can be implemented by anyone without restriction or intellectual property concerns 5a02188284
