            How to use AWS amplify securely
            Asked 2021-Dec-23 at 13:36

            I'm experimenting with AWS amplify. In particular, looking to provide a means for a user to change their cognito password. I don't understand how that is done in a secure fashion given the client id is exposed.

            What am I missing?

            Amazon Cognito throws an error if I try to sign in a second time with social sign in (Google/Oauth)
            Asked 2021-Sep-15 at 07:24

            I am writing here to ask for help or at least a clarification.

            I work at a startup and a couple of weeks ago we launched our SaaS. We manage all our users with Aws Cognito. I'm using amazon-cognito-identity-js for the authentication on the frontend and both sign-up and sign-in work fine. We want to add social sign-in (OAuth) through Google and for that I'm using aws-amplify-js, calling Auth.federatedSignIn({provider: 'Google'}) as specified in Amplify docs.

            The first time a user sign in with Google, a new user is correctly created in Cognito, but if I try to sign in again with the same user I get the following error: #error_description=Invalid+user+attributes%3A+email%3A+Attribute+cannot+be+updated.%0A+&error=invalid_request.

            Apparently this is a rather common issue:

            After looking for a solution I believe this happens because when we created our User Pool we set email as a required attribute and it was automatically set as immutable. Apparently if you want to use social sign-in every attribute should be mutable (as specified here because on every new sign in Cognito tries to update them.

            So now we're stuck. It's not possible to change email attribute from immutable to mutable for an existing User Pool and as far as I know it's not possible to prevent Auth.federatedSignIn({provider: 'Google'}) to update every user attributes.

            We cannot simply delete and recreate our User Pool because we're already in production and we got several users already registered. Is there any possible solution or workaround to fix this? Any kind of suggestion would be very helpful!

            Answered 2021-Sep-15 at 07:24

            As of now there is nothing more you could do then to migrate all the users to another User Pool.

            For users using federated sign in this won't change anything. You don't store their passwords so they won't see any difference.

            The problem starts with users for which you has passwords. While you can migrate them to another pool, they will have to set up a new password.

            You could write a simple script that could create a CSV file with the user data and then use the import function of the new User Pool to import all users. All non-federate users will then need to set new password.

            You can just notify all of them that this will be happening because the whole operation will involve some downtime (since you don't want the two pools to get out of sync).

            React Native: What is returned by Auth.signIn()?
            Asked 2021-Jun-18 at 14:39

            I am developing using react-native with Amazon AWS as back-end. I am also using amplify library.

            For logging in, I am using the below call:

            const user = await Auth.signIn(...)

            https://docs.amplify.aws/lib/auth/emailpassword/q/platform/js#sign-in

            https://aws-amplify.github.io/amplify-js/api/classes/authclass.html#signin

            My related questions:

            1. I get a big JSON in the user variable. I believe it is the AWS credential?

            2. The above signIn() call DOES NOT return a JWT token, it returns AWS credential. Is it? Also see the post:- https://stackoverflow.com/a/59327655/15943787

              Above post mentions:

            After successfully authenticating a user, Amazon Cognito issues JSON web tokens (JWT) that you can use to secure and authorize access to your own APIs, or exchange for AWS credentials

            What is meant by above statement? What is Auth.signIn() doing? getting JWT token or credentials?

            1. Does this returned credential get stored inside the mobile device? By default in android it is stored un-encrypted. Right?

            2. Is it stored in sharedPreferences?

            ...

            ANSWER

            Answered 2021-Jun-18 at 14:39

            The Auth.signIn() returns a CognitoUser Object as defined in the API Docs.

            Below is from AWS SDK for Android but the data in Javascript is the same, (found here). The JWT Token in stored in the CognitoUser.CognitoUserSession attribute.

            Represents a single Cognito User. This class encapsulates all operations possible on a user and all tokens belonging to the user. The user tokens, as CognitoUserSession, are stored in SharedPreferences. Only the tokens belonging to the last successfully authenticated user are stored

            So to answer your questions:

            1. I get a big JSON in the user variable. I believe it is the AWS credential?

            The user variable is a CognitoUser Object, which represents a single CognitoUser. to get the JWT token try user.sessionId or user.tokenId

            1. The above signIn() call DOES NOT return a JWT token, it returns AWS credential. Is it? Also see the post:- https://stackoverflow.com/a/59327655/15943787

            It updates the CognitoUser with session and token JWT. Check the user object to find them, after Auth.signIn() the user Object would have updated if AWS issued tokens

            1. Does this returned credential get stored inside the mobile device? By default in android it is stored un-encrypted. Right?

            Its being stores in Shared Preferences. so yes it's on device and un-encrypted. But AWS manages updating the and changing the JWT as the user interacts with cognito automatically.

            1. Is it stored in sharedPreferences?

            Yes, it is stored in sharedPreferences

            Failed Cognito Federated Sign-In with Google
            Asked 2021-Jun-06 at 08:18

            I am working on a project where we have existing Google Sign-in and we would like to convert to AWS Cognito so we can get username and password authentication as well as other social logins such as Facebook in the near future. In a feature branch of our API, we have working Cognito authentication via JWT. My current issue is exchanging the Google authentication response payload for Cognito's JWT.

            In our JavaScript, I am able to get a Google authentication response object that has the tokenId field. It is my understanding that I should be able to exchange that with Cognito for their JWT that I can use for interacting with my API. I have the Google app created and configured in the Cognito User Pool.

            What has been frustrating in trying to figure this out is that all the documentation seems to focus on new apps or just on the hosted UI for Cognito. I have dug through GitHub issues and blog posts that claim this should be easy. I'm hopeful I'm missing something easy.

            For reference, here is the code I have to sign in with Cognito and extract the JWT.

            How to use AWS Cognito as a provider in Passport?
            Asked 2021-Apr-25 at 00:06

            I have a Javascript backend (NestJS with Express + Passport).

            I would like to outsource the complexity of authentication (e.g. social auth) to Cognito but avoid getting locked in. I was wondering if I can use Cognito as a provider in Passport, similar to social providers (Google, Facebook, etc). That way, I could integrate many providers with the effort of integrating just one. I would still manage user data, authorization, etc in my own app, therefore, if I wanted to in the future, I could implement Google, Facebook, etc. social auth in my own app and get rid of Cognito.

            If I understand it correctly this is possible with Auth0.

            Ideally, I would like to implement an OAuth flow where the user is redirected to a simple "sign up / log in" Cognito app, logs in, gets redirected to a callback URL in my app where I receive user data. If AWS doesn't host a solution for this, I can also use their UI elements to build & host this app.

            If implemented as a provider / strategy, this could be as simple as:

            If you are already getting your hands dirty managing your user data I would integrate directly with the social providers. Cognito is most useful as a cheap and dirty place store user data and to host managed authentication and authorization services. You are already storing your own user data and sounds like you are only supporting social login; Cognito might be more of hindrance in this situation.

            Additonally, there isn't some magic that powers cognito social logins, you have to go through the same configuration steps if you were integrating directly, only difference is cognito will act as the callback endpoint.

            But if you want to forge ahead while avoiding vendor lock-in use it strictly as an OIDC service provider and use a generic OIDC strategy with passport or just remove passport altogether as you don't really need it in this situation, then as auth0 recommends use the oidc express middleware to protect your endpoints and use something like AppAuth to get the access token in your frontend.

            Amplify Auth.signIn() ClientMetadata not sent to Lambda Trigger
            Asked 2021-Feb-22 at 23:46

            We are moving our auth to Cognito and need to alter the token we get from Cognito. We are using a Pre Token Generation Lambda Trigger to accomplish this. We are also using Amplify's Auth library. However, I can not access the clientMetadata we are sending with Auth.signIn().

            On the front-end we simply have:

            Try setting the metadata value using Auth.configure before executing Auth.signIn. On one hand, it doesn't look like the sign-in event is a pre-token lambda trigger, which explains why the metadata isn't being passed. I appreciate that this is not especially intuitive. That said, on the other hand and assuming you will need to access the same metadata value when tokens are generated as part of a refresh, you'll likely need to cover additional non-initial-signIn events anyways. Using Auth.configure looks to do the trick for both.

            Error: User is not authenticated amazon cognito in nodejs
            Asked 2021-Jan-30 at 08:57

            I am using amazon-Cognito-identity-js and aws-sdk to setup authentication in my nodeJs app.

            What i did

            First i signup using userpool.signUp(..) method according to docs. Then i confirmed the verification code using cognitoUser.confirmRegistration(..) method according to docs.

            Up to here, everything works fine. But, now i would like to get all attributes of the user. I found a method cognitoUser.getUserAttributes(..) which can give me attributes. But when i call this method after cognitoUser.confirmRegistration(..) then it returns Error: User is not authenticated.

            I went through a SO question where I got getCurrentUser() will return null at backend side.

            So, how can I authorize any user at the fully secured backend side using nodejs?

            ...

            You have to first call the authenticateUser method:
