I've been trying to use the authenticated code provided from Auth0 and AWS Cognito to authenticate a user but when I go to the AWS Cognito Console dashboard I see no identities have been created.
Logic flow should be this: I get my JWT from Auth0 when a user logs in and I use that to get my AWS Cognito Credentials - I use the following code:
CognitoAWSCredentials credentials = new CognitoAWSCredentials (
"us-east-1:11047a24-xxxx-xxxx-xxxx-111111111", // Identity Pool ID
Amazon.RegionEndpoint.USEast1); // Region
credentials.AddLogin("stef.auth0.com", id_token1); //id_token1 from Auth0
I did input the JWT (id_token1) into jwt.io to check the validity of it and it comes back VALID SIGNATURE when I add the Auth0 Client Secret. I am not able to see any errors when I run the code. I am using Xamarin C#. I did all the necessary setup with configuring the provider, setting up the default IAM roles for Cognito Auth/UnAuth. Put in the correct Auth0 client ID into AWS, etc... I can however add an Unauthenticated user but not an Authenticated user.
Am I using the wrong code here? Can someone point me in the right direction please?
Thank you for looking!

I am new to AWS Cognito. Based on description, Userpool is used for authentication. If I am a user in the userpool, I can use this user name and password to authenticate my identity. Why do I need to add App to userpool?
Thanks for help in advance,
AWS Cognito allows you to create a number of apps to integrate with your user pool. On each app, you can custom the Authentication flow, Access/Refresh token expiration, attribute read and write permissions, hostUI...
Use case: you use the same user pool for both apps but there are some custom like:
App A: just allow authentication via the ALLOW_USER_PASSWORD_AUTH and access token expiration is 5 minutes.
App B: just allow authentication via the ALLOW_USER_SRP_AUTH and access token expiration is 30 minutes.
Hope that's clear.
I have setup an userpool with two login methods. One using hosted UI with userpool to signup/sign-in users. And ther other using a Federated Identity Provider (IDP). For both login methods(Appclients) I have enabled and used Code Auth Flow + PKCE (So the code <-> token exchange could be completely handled by the client - react web frontend).
I have also setup an Identity pool for users' to get temporary credentials to complete the MFA (TOTP) setup from react web frontend.
Now, I could complete the MFA setup - showing the QR code (AssociateSoftwareToken), performing VerifySoftwareToken (after user gets the one time token using code generator app- google authenticator in my case) and updating userpool for user's preference with SoftwareTokenMfa settings.
When users Login using the hosted-UI (with useraccounts created through Cognito ), Cognito performs the MFA challenge before redirecting with (oauth) code.
But when users logged in using Federated Login, Cognito redirects the user back to application with oauth code.
Is there anyway, I could make Cognito perform MFA for users logging-in using Federated Login?
We're developing a website with AWS Amplify that uses Cognito to handle the authentication. I've configured the user pool in Cognito to use Keycloak as the OIDC IDP. The basics of logging in and out are all working as desired.
I now want to get more information back from Keycloak into the Amplify app. If I use https://openidconnect.net/ as a test point for authenticating to Keycloak as if it was Cognito, I can decode the JWT in https://jwt.io and see the additional information I'm after.
In Cognito, in General Settings > Attributes, I've added a custom attribute "groups":
In General settings > App clients, I've marked that attribute as readable:
Under Federation > Attribute mapping, I've mapped the OIDC attribute to the User pool attribute:
but, when I authenticate in the web application and dump the payloads for the ID and access tokens, I cannot see the "custom:groups" attribute.
What am I missing or misunderstanding here?
Thanks.
is it possible to use AWS Cognito that has a custom authentication flow enabled, while also using an external identity provider like Facebook or Google? I've tried this with Facebook and the Cognito Hosted UI, but my DefineAuthChallenge-trigger was not hit.
I contacted AWS Support and they pointed me to the Cognito documentation here where a note says that
The Amazon Cognito hosted sign-in web page does not support the custom authentication flow.
As an alternative, this solution was proposed:
Alternatively, if you would like to use custom authentication flow with an external identity provider, you will have to write your own custom login flow using one of Cognito's SDKs and use Facebook as a way of login.
My idea is that you can probably do this by defining a custom challenge, that asks, which identity provider you want to use, as the first, initial challenge. If Cognito is chosen, the user needs to provide their SRP-stuff or username and password, if that is enabled. If Facebook is chosen for example, you would probably need to send an auth challenge to the client saying that you want a token or code from them, which can only be gotten, if the client shows the website with the Facebook login. The challenge response to the server would then be the gotten auth token from Facebook or code or some other answer that the server can then use to authenticate the user within Cognito, where the Facebook app is connected and is registered as an external identity provider
This is my idea of how I would go about to do this, but I haven't actually implemented this. I hope this helps someone trying to do this though.
I have an Android app and an API secured with Auth0.
I'm developing an app for a new client, who has a large Cognito user pool.
Is it possible to use my current Auth0 setup to log in Cognito users via email/password and receive a Auth0 JWT?
I don't want to create a new Auth0 user for each Cognito user. At least not explicitly.
Thanks
If I understand you correctly, you want to use Auth0 as a service provider and AWS Cognito as an identity provider. In theory, you can use SAML protocol to achieve that. Try the following:
Configure Auth0 as SAML service provider. https://auth0.com/docs/protocols/saml/saml-sp-generic
Configure AWS Cognito AS Identity provider: https://docs.aws.amazon.com/cognito/latest/developerguide/cognito-user-pools-managing-saml-idp-console.html
Then, once you initiate the login flow in auth0, users will be redirected to AWS Cognito for user authentication. After successful user authentication, AWS should redirect the user Auth0 with SAML Assertion. In that stage, Auth0 will validate the assertion and will issue a JWT token. The user will be redirected to your application with JWT. Note that if this is the first login, auth0 will create a user profile.
https://auth0.com/docs/protocols/saml
The following AWS documentation explains how to configure auth0 as IDP.
