I have just started working with react native and the backend of my app is handled by another company. I have a very simple login/ register feature where for register the user needs to enter the following fields (Name, Email, Password) . To login its just email and password. I am expecting a Json Token and the information like name in return.
I need to ask the backend company for this service but have never documented something like this. I Was wondering if anyone could direct me to some documentation of this flow that i could send to them
Is this the sort of flow you're looking for?
https://jwt.io/
It is a standard created by the company Auth0, which provides authentication-as-a-service.

I've been searching around and couldn't find a good solution to this.
I'm working on a school project that built upon HTML (Making a bunch of pages) -> CSS (Styling the pages) -> JS (Adding some functionality) and finally backend using whatever we want.
I've used mongodb and node/express to have a functional sign up and login and it works via POSTMAN, but I'm not sure how to connect that to my existing html file that was made for a prototype sign up/login.
Any advice?
There's several things you need to consider.
If the goal is to authenticate users through your backend you need a way for your front end to communicate to the backend and check whether or not the user is logged in. To do this you'll need the express server to validate the user's login information and send a token back to the user. The user can then use this token to access protected routes on the server.
You can send a POST request to your server containing the login information with the axios library, and have the server redirect the user to a protected url upon a successful request.
I couldn't explain how to do this in this post alone, but here's an excellent tutorial on how to get started.

It sounds like you already know what to use for backend, but not frontend.
You need to choose frontend such as React, Angular or Vue.js etc.
and connect your backend to the Server if it makes sense to you.
I recommend to look up React tutorial ( Or any other Frontend ) and move your HTML, CSS and JS to the project first.
Good day everyone. I am stumped at the moment and would appreciate some guidance. I feel like I am a great googler to usually find my answers or resources but for the life of me I can't seem to find any good learning material on JSON requests and responses.
So I took a course that builds a 3 part app. Web app with Django, and 2 mobile apps that make API calls to it. The instructor uses Facebook authentication from the mobile apps and I am trying to set up the apps for username and login and a registration page as well.
I have django models setup and and can make users from the web app but I can't seem to wrap my head around how to make JSON calls from app to Django. When I search for possible terms like authenticate django I get results that talk about only django usage.
Does anyone have some tips or links to resources that would help me understand the login process better. I realize that almost every app has a login which is why I'm surprised that I can't find any good learning material on how its done. Or I'm just searching for wrong keywords.
Any help would be great thanks.
It's really a general question, But i give you a brief on how mobile and django server should interact with each other:
First of all, in your situation I really suggest to use django rest framework, Because of it's rich modules and functionallity like serializers, routers and ...
read more about it from origin documentation here.
For authentication system, You should use a token based system (or session). I suggest use one of django suggested token based solutions for that. In my case i really suggest to use django-restframework-jwt library
(JSON Web Token Authentication support for Django REST Framework).
so whenever you want to send a request to mobile you should provide that token (based on token authentication backend you choose) in your headers of request.
And for login and register you should create APIViews that takes user input, then register or authenticated it with backend and then gives user the generated token for future requests.
And for social auth system like facebook, the main concept is to redirect user from app to facebook oauth links, which if the user authenticate in his facebook will redirect you redirect url of your backend server, then you should capture that request in callback, fetch data and create or get the user and generate the token for that user and return it. so that for furture requests, by sending token to server, server will know that which user is sending this request and handle response properly for that.
And if you want to create a login with mobile, then you need to setup APIs for login, register with django rest which is really easy and you can learn from it here.
I have used lifeary service builder to build my services. some of my services require that the user is authenticated before he can use them.
how can i generate an auth token and send it in the header or in the URL?
I have tried username#host.com:password#http://localhost:8080/PortletName-portlet/api/jsonws/?serviceClassName=com.service.NameServiceUtil&serviceMethodName=getMyNames&serviceParameters=[userid]&userid=1
and it did not work!
I have made sure i have added the below line in my portal-ext.properties and restarted the server.
json.service.auth.token.enabled=true
What more should i do to be able to pass Auth Token? is there a better method that i can use?
You actually want to use AuthVerifier. This is the best way how to access the Liferay API and be authenticated. It similar to the autologin concept.
Have a look at https://dev.liferay.com/es/discover/deployment/-/knowledge_base/7-0/authentication-verifiers and check out the PortalSessionAuthVerifier class in the source code.
The concept is quite simple. Read the request object and determine who the user is. Perform your custom authentication and return the auth result with the user identification.
I am trying to work out an application using
Dotnet Core 1.0
MySQL as the data store
Authetication and Authorization
Entity Framework
Ubuntu 16 machine
I have succeeded in creating a sample API to fetch data from MySQL database using entity framework. Now I want to introduce Authentication using email as username and Password.
I tried several method from different blogs but unable to achieve this.
What I am trying to achieve is Custom Authentication for the api where user will send username and password to login Api. The login Api will return an access token and refresh token. Using this access token, the user can call other APIs.
Later on I want to add Google and Facebook Authentication too.
Is there a way to do this?
Everything you want to achieve is possible. However there are some caveats.
Yes you can do this. You will need to use the resource owner grant which is turned off in identityserver 4 by default. I suspect the reason for this is because passing user credentials into an application is an anti-pattern, it is there to typically support legacy systems, also it does not authenticate users in the explicit sense because the credentials could come from an un-trusted source (as an example). You can read up about the grant's generic value here. You can find samples here.
The safer pattern is to use something like Implicit Flow which is good practice if you cannot guarantee trust between clients and your API.
As for social logins this is possible. There are tonnes of samples online but here are the official docs.
There is a project on github, https://github.com/diogodamiani/IdentityServer4.MongoDB and a corresponding nuget package that will send you in the right direction. It's obviously MongoDb, but the same premise applies.
I am working on an Identity management application, using which my goal is to manage users on Box application.
I was going through Box documentation, and there are two ways for authentication
OAuth 2.0, which has redirection URI as required parameter. And due to which I cannot make use of it, since I will not be able to enter username and password and Authorize dynamically using my Java code.
Reference: https://box-content.readme.io/reference#oauth-2
JWT authentication, this I can use in my code and successfully get Access token. But problem here is, this access token can only be used to manage App Users (who will not have login to Box website).
Reference: https://box-content.readme.io/docs/box-developer-edition
So, is there any other authentication mechanism which I can use for getting Access token for managing Box users?

The current best option is #1 with a process like this:
Create a Box application with the 'Manage an Enterprise' scope enabled.
Use a web-based access token generator (such as this or this) to get an initial access/refresh token pair. Save these somewhere safe (flat file, DB).
Code your application to initialize itself with the access/refresh token pair from its saved location.
When the access/refresh token pair is refreshed, write them out to the save location.
If your application runs across multiple nodes/processes this approach will require some (painful) coordination between them. I believe Box is working on some improvements in this area, so you may not have to live with this for long.
