I want to use Ionic to connect with a Laravel rest API. As far as I know I should use OAuth to authenticate the user. How does this stop other clients/requests from accessing my rest API?
For instance if someone created another Ionic app or anything and requested a OAuth token.
AFAIK there's still no way to perfectly protect your API source. As you mentioned, OAuth is one way to help protection.
I often use JWT, aka. JSON Web Token with token-refresh which expires right after one use. You can check out my short tutorial on using JWT with Laravel and AngularJS, which is absolutely same with Ionic.

I'm working on an Absinthe GraphQL API for my app. I'm still learning the procedure(so please go easy on me).
I've a Absinthe/GraphQL MyAppWeb.schema.ex file in which I use for my queries and mutations. My question is how do I use this API for authenticating the user on both Mobile and Web app?
How do set a cookie(httpOnly & secure) in my web app and access/refresh tokens in a single Absinthe API to serve my website and mobile app. Basically what I'm trying to learn is how do I authenticate the user based on specific platform.
If my question sounds bit confusing, I would be happy to provide more information related to my question. I would really be grateful if someone could explain the procedure, I've been very stuck on this for a while.
I would avoid using authentication mechanisms provided by absinthe(if there are any). Depending on what front-end you are using, I would go with JSON API authentication. The flow on server goes the following way:
Create a endpoint for login that will receive a user and password and will return a refresh token.
Create a endpoint for exchanging refresh token for access token.
Use a library like guardian to generate your refresh/access tokens.
Create a phoenix plug for authentication that will check your tokens, guardian has some built-in plugs for this.
Now on device you have to implement:
Ability to save refresh and access token on device.
Have a global handler for injecting access token on authorized requests.
Have a global handler for case when access token is expired. (you usually check if your request returns Unauthorized, then you should request a new access token from the server using your refresh token)
This seems like a crude implementation, however I would advise in implementing your system instead of using a black box library that you have no idea how it works under the hood.
I am trying to secure an endpoint in spring boot using Azure spring boot libraries. I'm following the samples from https://github.com/microsoft/azure-spring-boot/tree/master/azure-spring-boot-samples/azure-active-directory-spring-boot-sample
I can't get a clear answer if I should use Id_token or Access_token when making the API call from my front end application written in React.
https://learn.microsoft.com/en-us/azure/active-directory/develop/access-tokens
I think docs from this link above states that I should use Access_token to secure the endpoints but, in that azure-spring-boot-samples, they used id_token to make the API calls.
I've tried to use the same code and test an API call. API call is successful if I use id_token in header. It fails signature check if I pass access_token in header.
I figured this out after understanding the big picture. All applications either front end or back end most likely should be using different app IDs. On Azure portal I would define which app have permission to call which API. Then, when I get access token, I would have to specify what app I am getting access to. This is laid out in MSAL doc from Microsoft. https://learn.microsoft.com/en-us/azure/active-directory/develop/msal-acquire-cache-tokens
Also, only the access_token allows you to assert claims for things like Role Based Access Control in the token. The ID token is usually shorter lived and has less information. In general it is a better practice to use the access_token.
I have a website which is based on a Laravel backend api and a Nuxt.js frontend app.
The laravel app is served at api.website.com. Till now the api was open, meaning everyone can make a get request. There are almost no post requests.
I know need to implement a login mechanism for the users (Usual login+register and facebook login).
My question is about how would I go to make this process secure. Do I need Laravel Passport (or other similar mechanism)?
My thought is that, say I have an endpoint api.website.com/register (POST), I do not want anyone to be able to just make a post request and create an account. I need to have some sort of security like a csrf token. I know I can use CORS but that doesn't really provide much of security in this case.
You can use jwt like this or laravel passport.
I am making a VueJS app with a Laravel backend. I see Laravel has Passport which is used to authenticate/authorize APIs. (Sincerely I have not yet succeeded in integrating Passport. I have not understood where the starting point is. Will post that question separately).
I have done a lot of searching and still have not found the best/easiest way of doing authentication and authorization, and also interface control depending on permission. (I know "best" is subjective but basically means a method that is easy to integrate, understand and use).
Anyone who has been there and used one that worked really well?
I generally use JSON Web Tokens for my web and mobile apps. It's simpler to set up than Oauth and is a better fit for many applications.
Basically, the user sends a POST request containing their authentication details to the appropriate endpoint and receives a token in response. The user can then include that token in the Authorization header of future requests to authenticate them.
The token also includes a timestamp for when it expires, and it can be decoded on the client side so that an application can refresh the token before it expires.
There's an excellent implementation of JWT for Laravel which I use all the time and can highly recommend. There are also client-side libraries for handling JWT with pretty much every framework under the sun.
#MatthewDaly, I followed your recommendation and I stumbled on a VueJs-Laravel JWT implementation here: http://jimfrenette.com/2016/11/laravel-vuejs2-jwt-auth/
I followed through the Tutorial and was able to make it work for my case. (Caveat: The post is slightly old (using Laravel 5.2), but with good understanding of Vue and Laravel, you can be able to follow and implement it easily).
I'm thinking to develop a full-fledged Identity System in Laravel 5 with Passport.
Following is my requirement:
I should have main identity management app like identity.mysite.com where all of my users are stored.
I have 2 other applications APP1, APP2.
When user request restricted resource on APP1, (s)he should get authenticated by identity.mysite.com
Once authenticated, let user access resources on APP1
Meantime, if user decided to access restricted resources on APP2, (s)he should not be asked to put credentials again.
Things I've tried:
simpleSAMLphp - SAML is an option which does these things for me. But it is not as mature as OneLogin and I'm not thinking to go in SaaS model at this stage unless it is necessity.
Laravel Passport - oAuth 2.0 seems tempting. I can even use, Passport Grant Tokens but I'm unsure on how reliable it is over SAML. Also, Laravel Passport is being widely used to authenticate API. Is it going to be useful while authenticating traditional session based apps? I haven't seen any example where the proper SSO is implemented with more than one application and laravel passport.
I know OAuth 2.0 is not an authentication protocol. Rather it uses something called Authorization but we probably can make it work to support Authentication protocol as mentioned here. Is it something, that Laravel passport supports?
This is what I call a resource oriented approach where all the clients(app1, app2...) want to know weather requesting user is authorized to access the resource or not...
Here we need to shift all the authenticating logic to oauth and make all our requesting apps dependent on OAuth. This way if user request app to access resources then if:
Token is present then app will request oauth server to validate given token and if found true then app will provide access to user.
If token is not present then you can solve it by asking for credential and app will transfer user data to oAuth server and validate it respond with the token.
As per my experience I use to implement this approach and I think Laravel Passport is an abstraction layer over top of your authenticating system. You can mold it however you need. There are few more enhancement and advancement can be done but this would work as a basic layer over top of your SSO.
You can achieve this with passport however you are right about the examples as there are not many or lacking on some steps.
You could to create a new middleware in App1 and App2 side that communicates with identity.mysite.com and gets the user data (token, scopes, etc, id) then it will verify if the token is valid.
On the passport server side you need an endpoint to return whether the token is valid or not and any additional info.
To avoid making too many requests to your passport server i would recommend to create a service that get the TTL of the access token and set it as the time on cache on App1 or App2 for the user data.
