I know that OAuth2.0 is framework using to authorization data request between apps, but to give this access auth server is required. It is my question: who is this server? Let's say: We have two apps: Twitter and Google. I am trying to register Twitter account using Google account. And now where is this auth server? Is it Google? Or maybe it is another third server (managed by Twitter and Google together where user data is?) If it is Google, how Twitter is able to check if user token (generated by auth server [Google??]) is valid?
Thanks
On your first question,
I am trying to register Twitter account using Google account. And now
where is this auth server? Is it Google?
Yes, it's Google. If you're trying to login/register to Twitter via Google, Google is the authorization server. Because, Google has to authorize/delegate access to Twitter to access your data such as your Gmail id, username, etc.
Once you click on "Sign up with Google" button on the Twitter registration page, you will be redirected to the Google login page first (to see if you're an authenticated google user) and then Google would show you a consent page saying that "Twitter is trying to read your profile data, are you okay with this?". Once you click on "Allow" button, Google will generate an access_token, id_token, and refresh_token and pass it to Twitter.
On your second question,
If it is Google, how Twitter is able to check if user token (generated
by auth server [Google??]) is valid?
Twitter is not going to validate the tokens. Twitter can pass the token to retrieve your Google profile information from Google's Resource Server (where all your data reside)
Google's Resource Server is the one that's going to validate the token. It first checks the 'iss' claim of the token to see if the token is issued by Google's Authorization Server. Additionally, it would check for 'aud' to see if the token is issued for them (recipient of the token). Finally, it checks for the 'scope' claim to see if Twitter has the right access to request the data. For eg, they would need to request only read-only access to your profile, but not write access. There could be additional validation depending on the use case.
I hope this answers your questions.
I'm a bit of a salesforce / web noob, but am testing out the customer 360 external identity licences, along with customer users. My main goal is to authenticate a customer user using OAUTH, get an access token, then use the Salesforce web APIs to access some relevant bits of info for the customer user. However I just can't seem to figure out how to get the customer user authenticated despite being able to do the same just fine for my personal admin user account.
I have the following setup:
a bunch of external identity licences
a profile with the external identity user licence assigned, with the API enabled setting checked.
a connected app setup with relaxed IP restrictions set, all users may self authorize set, OAUTH settings enabled, device flow enabled, and the full access OAUTH scope selected.
an end customer contact with an associated end-customer user, assigned to the external identity profile and thus external identity user licence.
And I'm POSTing to the test token endpoint (https://test.salesforce.com/services/oauth2/token).
I've tried two auth flows, password and device flow for IOT as I want to integrate this with a command line app (which the IOT flow is good for apparently), and while both succeed for my personal salesforce user credentials, they both fail for my test user account credentials.
The server response for the password flow is as follows:
{
"error": "invalid_grant",
"error_description": "authentication failure"
}
End-customer users don't appear to have a security token so I've just been using the password on its own. I can't seem to find a way to generate a security token for these types of users but suspect this could be the issue for this flow.
When trying the device flow the returned verification uri is always https://test.salesforce.com/setup/connect but attempting to login on this page as the customer-user fails with this error:
Please check your username and password. If you still can't log in, contact your Salesforce administrator".
I am definitely providing the correct customer user credentials here so have no idea why this fails.
Does anyone have any ideas on how to get this working?
#eyescream nudged me in the right direction so here's the solution for anyone in the same position as me.
Authentication of external identity customer users is not done using the normal OAUTH REST endpoints (https://test.salesforce.com/services/oauth2/token or https://login.salesforce.com/services/oauth2/token).
Instead you have to setup an experience cloud site, add your customer user profile to the sites list of member profiles, then authenticate using a site specific AUTH endpoint.
For example, if your experience cloud URL is https://sandboxname-companyname.instanceid.force.com, then your OAUTH token endpoint would be at:
https://sandboxname-companyname.instanceid.force.com/services/oauth2/token
Extra things to note:
customer user accounts cannot authenticate using the username-password flow.
the device flow for IOT (or command line apps) will return a verification URL that customer users cannot log in to (https://test.salesforce.com/setup/connect). You can instead use the experience site connect URL (https://sandboxname-companyname.instanceid.force.com/sitename/setup/connect)
My application needs to log in to each user and generate the bearer token for each of them. By using the bearer token I can fetch the result using Twitter API v2. Anyone, please help me how can I do that.
The bearer token is specific to your application, NOT to the user. Bearer token / app only authentication is JUST for the app, not for the user. The first time you create the app on the Twitter developer portal, you get the bearer token which you should save in your password manager.
The account token - when a user is logged in to your app - is different. If you need this, you can also generate it on the developer portal FOR YOUR ACCOUNT ONLY, or you can make your app implement sign-in with Twitter via OAuth 1.0A. These tokens will enable your app to operate for a user and port new Tweets, like Tweets, create lists, etc.
How to sign up a user to AWSCognitoIdentityUserPool and get the JWT tokens back?
I got Facebook token from facebook registration. Then how can I register user in the User pool with based on that token?
I need to get JWT tokens in responce after that to use them in my own backend.
Struggling with it a week already..
Recognize authentication is a two step process. First, your app must authenticate with Facebook to receive a JWT, it seems that you have done this successfully. Second, this JWT is exchanged for IAM credentials that will be used for API calls.
Authentication Flow:
App authenticates with Identity provider using the SDK for that identity provider. In response, the Identity provider sends a JWT that will be cached by the app.
App uses cached JWT to authenticate with AWS. If the Identity provider is configured in AWS, in response, AWS sends IAM credentials with the permissions granted to that identity provider.
IAM credentials are used to make calls to other AWS resources specified in the Policy
This documentation goes into more detail for these steps in regarding Facebook.
The AWS Amplify Library has support for iOS. I would recommend using this library to handle Authentication against Facebook Federated Identities.
You do not necessarily need a user pool managed in Cognito, as the user pool function is managed by Facebook.
How do I secure my API when I want an app to be able to retrieve app-specific information without a user logged in and when I have an OAuth provider for another section of my API? Can I use the client app's OAuth credentials to hit the API without a user logged in?
I have create an OAuth provider and client using doorkeeper following railscasts 353. I can successfully authenticate a user to my provider app and make requests on behalf of the user to my provider API.
However, a portion of the API is user independent, meaning that the information returned from the API is not specific for a user and therefore a user should not have to be logged in. For example, assume an ecommerce site and items and prices are stored on the provider for multiple clients. I want a client app to be able to securely retrieve the items/prices associated the retrieving app without a user having to be logged in. So if you went to example.com the items would be displayed even if a user is logged in via OAuth.
I have only be able to retrieve this information via OAuth when a user has logged in through OAuth (creating an access_token). Is there a way to use OAuth without having a user present (I've been trying to read about 2-legged OAuth and if that is an appropriate solution)? Or do I need to use Api keys (or Http Basic Auth) for the application to retrieve the application specific data?
If OAuth is not the right solution because I do not have a user present, could/should I use HTTP Basic Auth over SSL and use the client site's OAuth secret key as the API key for the basic auth username?
If you need to authenticate your client apps in you API (without requiring a user specifically) use the Client Credentials flow
