I use Users API on Google AppEngine (java).
I have a core servlet - /api - (JAXB Jersey Implemented) which exposes CRUD operations. Currently, allows me to define that only logged in users can access that. So, users who have logged in on the site using OpenID or Google Federated Login can login and access that through the app.
Now, I want to publish API to the developers - /dev/api. We generate an unique API key for them to acsess the application.
How do I expose the same /api functionality under HTTP basic authentication without compromising the existing functionality? App Engine does not support custom security roles ().
How do I implement HTTP basic authentication? Should I use a filter on /dev/api and restrict in that filter?
This was simple.
I created a different filter (BasicAuthFilter) for my new URL pointing to the same Jersey resource.
It fixed it.

Using django-allauth I've enabled google authentication on backend. I can sign in to my Django project and everything.
Now, I want to connect that authentication with my React frontend, so I can login/register using google on http://127.0.0.1:3000.
What do I need to do?
You can use Google libraries for javascript or some npm library that does that for you.
After logging in through Google account and getting associated authentication keys / data on front-end side, you send them to Django and django-allauth should handle that data for you - you have to have specific view for that linked in urls.py.
After such request either new social account will be created or already existing logged in.
It might be required to adapt some of original social account management views to handle data that you send from React.
Keep in mind that at the moment Google is switching to Google Identity Services, which works a little bit differently than old method implemented in django-allauth - there is already an issue raised in the repository.
https://github.com/pennersr/django-allauth/issues/3074
To use Google Identity you can try to use:
https://www.npmjs.com/package/#react-oauth/google
or any other library that supports this
After that if you want to do this yourself new way on Django side, you can send JWT token that comes from Google to Django, validate it based on Google documentation and then create social account / sign in. That currently requires overriding some of original django-allauth views / forms for social accounts.

I am building a reservation system in Google App Engine using Go. I need 2 forms of authentication in my program.
Public Form -- form built in Angular that is on our public website. I want my front-end to have some sort of credentials.json file to use when requesting the book and getOpenDates endpoints in my RESTful API running in Go on Google App Engine.
Private Companion App -- protected by username and password that the user supplies in my app built in Flutter. The app is requesting many endpoints in App Engine. I would like to use JWT to authenticate this portion, but I'm not 100% sure JWT is what I need.
I'm not sure if this tutorial on Identity Platform is what I want. I'm very new to App Engine and authentication in general, so I am a bit lost.
Please describe how I could implement these authentication methods in my RESTful API in Go running on Google's App Engine. I think I may be able to implement the username/password method using a tutorial like this but I'm very lost on the 1st form of authentication with just a credentials file as authentication. If I'm going in the complete wrong direction to accomplish what I want please tell me, but what I'm looking for is code or a tutorial describing how to authenticate using these 2 methods. Thanks for any help.
From what I understand, you want to have a golang backend API in App Engine that serves both your web frontend (1.) and your users app (2.).
I am going to suppose that any user with username/password can use both your frontends: the web app and the mobile app with these credentials.
The credentials.jsons are not designed to authenticate users of your services, but rather server to server communication.
With that in mind, I have found the guide Session based authentication in golang, that could help you to set up your backend to accept only authenticated requests over HTTPS. The web browser will automatically save the cookie, however you need to store the cookie in your mobile app.
For much more complicated scenarios for authenticating from different webpages, it is required to use OAuth2 as you can see in this thread. If you don't find any of your requirements listed in here it is probably overkill to use Auth0 nor OAuth2.
I currently have two app services
Web App (Asp.net core 2 w/ front end in react)
Web Api (Asp.net core 2)
Note: Both are configured with different Azure active directory app id.
user signs into Web App and retrieves a token for it's own appId/ClientId/ClientSecret stored in tokencache.
from the WebApp, the user wants to talk to a WebAPI but needs to get a token since it's protected with AAD as well but it's a different app id/client id/client secret.
Problem:
When I try to do a AcquireTokenSilentAsync() for the web api, I get an error throwing that I the token is not in the cache?
It also seems that with depending if your using AAD v2.0 or v1.0 will determine if the web app and web api can have different app ids. So it seems like i would have to use AAD v1.0. With Asp.net core 2, it's not clear to me what OpenIdConnect is using or configured to use under the covers.
Question:
It's not clear to me why the acquire token silent async didn't work and failed. Does that only look for the token in the cache; otherwise it fails?
Is it possible to configure the token from web app to have permission to access web api resources. I notice that in the azure portal, you can selected resources like microsoft graph, but I don't know how you would associate a custom API. In my case, I want to get it running on my local machine before I move it all to azure.
If the web app token does not have permission to access the web api, do i need to do another login authentication with the user even thou both are within the same tenant?
Any Advice appreciated,
Derek
Yes, AcquireTokenSilentAsync will look into the cache, and see if it can find tokens. If it does, it will check to see if the access token is still valid and return that back. If the token is expired, it will use the refresh token to fetch a new access token and return that back. When this call fails, it's an indicator you need to perform an AcquireTokenAsync (which will likely show UI in the case silent already failed).
Yes, you can associate a web app to get tokens for your own custom web API. I'd recommend using Azure AD v1.0 (register the app in the Azure portal, ADAL library). You'll need to register the two apps (web app and the api), both will be type web app/api. In the API, you can register an App ID URI which will act as the resource identifier for this API. In your web app, you'll want to go into the Required Permissions, and add the Web API you have registered as a permission. Then in your web app, you'll need to use the ADAL library (alongside an OpenID OWIN middleware) to acquire a token for the resource as specified by the App ID URI field. Here's a code sample that implements the exact scenario you're describing (Web App/API in ASP.NET Core).
I am currently working on a mobile application that will allow a user to sign in via username/password (OAuth 2.0 Password Grant), Facebook, Twitter, or Google. The backend for this mobile application is coded in Spring Boot/Cloud (Java) and makes use of Microservices principles. I have several small services that are discoverable via Eureka and make use of Spring Cloud Config for centralized configuration. They are all exposed to the Mobile device using Spring Cloud Zuul, which acts as a reverse proxy. The Spring Security OAuth 2.0 setup that I have takes in the username and password then returns a JWT token, this token is validated every time a request is made to the backend. I also store users locally in MongoDB and make use of Method Level Security. I want to add Social Login to my application and have it do the following:
On the Mobile Device do the OAuth dance and get an access token
Send the access token to the server, and using Spring Social create a new User locally and associate it to Facebook/Twitter/Google, and then return a JWT token that can be used to validate requests
This JWT token should be created by Spring Security, and I should still be able to use Method Level Security and have local users
Basically I want all the features I have with my custom Spring Security OAuth 2.0 Password Grant with Social Login
This is my first attempt in architecting a system, and therefore am looking forward to responses from those with much more experience than I have. I have seen many examples that use Spring Social, but all of them are for Web Apps, not for Mobile, this is where I am currently stuck at.
The questions I have are the following:
Is my suggested approach adequate? Are there other approaches that are stateless and better for mobile applications?
Is Spring Security OAuth 2.0 and Spring Social Security enough to accomplish this? If so, are there resources that I can use? I have not found many online.
Could Spring Cloud Security be used as a solution?
Should I consider using a 3rd Party provider for Authentication such as Auth0 or OKTA?
using OAuth2 for a stateless solution is in my opionion adequate, because of:
oauth2 in general is a protocol designed to be usable in every client, which is able to perform http requests. Since the social nets you mentioned all support OAuth2. If everything goes bad, you still can consume them manually respecting the oauth2 specs, which they implement.
in general I see a problem with "authenticate with XXX and use that token as JWT for my requests". This is not directly possible, because that token is for their resource servers. Instead you need to separate 2 processes: authentication and authorization. In short you can use the socials endpoints to authenticate a user in your backend, which leads to a second oauth2 generation from your authorization server. This can create a JWT using all features from spring-oauth.
This libary should used in addition, since it helps to setup a application wide security solution. As example, you keep an own authorizationserver (which authenticates using social login) and several resource servers. spring-cloud-security helps to build things on top of that, as Zuul SSO, hystrix+ribbon powered feign clients respecting oauth2 authentications and so on
I don't thing this will help you, because those services primary serve you as an identity provider, while you are going to couple your users identity over social networks
I hope I could clarify your question in some way
I have achieved it by referring two spring example applications. Check this
steps, you will be able to achieve social sso login with Zuul, Auth-server and multiple back-end REST projects.
I want to implement some form of access control for a REST API implemented in App engine. Is it possible to get the list of GAE Applications that a user has permissions to administer or view in the app engine console. Or whether the user has permissions to administer/view the current application.
Note: the Users API does not work for me because this is a rest server called by another google app not a web service called by a user from the browser. OAuth API seems promising but I was unable to find an OAuth scope or rest endpoint for getting GAE related information.
there is no API that can provide a "list of GAE Applications that a user has permissions to administer." Google Cloud Endpoints on App Engine (Trusted Tester program) may be useful for hosting custom RESTful APIs with user authorization may be useful, read more here: http://endpoints-trusted-tester.appspot.com/
There must be an API as the Google Eclipse plugin is using it.

But it is not documented.
