Azure Active Directory get access token - azure

I'm kinda stuck on how to get the access token from a webview login.
I have a link working but after they type in a code / password I want it to send the token back to the client device. How do i do this?
Current redirect uri is https://login.live.com/oauth20_desktop.srf.
In addition, it shows a stay signed in page - how do I disable this?
Lastly it shows another page saying let this app access your info?
Is there any way to get rid of this (getting verified?) so it closes like lunar client after finish.

• I would suggest you to please refer to the below community thread for receiving an authentication token through webview on Android. In this code, you add a ‘WebAppInterface’ in which the android function should accept the token as a parameter after the user has successfully logged in and got his token. In that, you must register the ‘WebAppInterface’ as ‘webView.addJavascriptInterface(WebAppInterface(this), "Android")’ based on which the Web frontend can invoke the function like ‘Android.consumeToken(token);’
For more details, kindly refer the below community thread for reference: -
How do you obtain a Authentication token using WebView in Android?
Also, it depends on the type of applications used by MSAL for your webview application running on Android to achieve SSO, i.e., through a system browser or through a broker application. Therefore, for setting up the same as stated above, ensure that you are putting the below line in the app configuration JSON that is passed to MSAL: -
"authorization_user_agent" : "WEBVIEW"
Thus, when using the in-app WebView, the user signs in directly to the app where the tokens are kept stored in the application itself and still SSO can work effectively. Kindly refer to the below link for more clarification as it describes the required steps to be followed for using SSO and getting an access token through MSAL authentication on webview: -

Azure AD authorization directly from mobile app

I'm working on Xamarin.Forms application where user should Authorize using Azure AD B2C. I've managed it just fine using this library.
Now I'd like to know if it is possible to authorize without redirecting to webview. When user enters email and password on app send a get request directly to an url and receive access token, refresh token and etc. Just like in OAuth 2.0.
I've researched and found out that skipping the webview authentication part is doable but extremely not recommended for security reasons but anyway, would be glad to hear any solutions.
Webview runs on SSL (https) and hence transmission of user credentials for authentication is secured.
It’s worth noting that you don’t have to use a web view for authentication; you may create your own user interface for this flow and pass the information back to MSAL.
- this is mentioned on the same blog-post which you referred to.
All you have to do is to design your own interface and pass back the login info. It seems like a little work to do.

how to get Azure Active Directory B2C working with Bot Framework?

so far I've not been able to get this working with the bot framework. I spent all day but only managed to get .net api example (https://github.com/AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet) working with AD B2C. I'm not sure where it grabs the bearer token that I want to pass to BotUserData...
I've tried following https://azure.microsoft.com/en-us/blog/bot-framework-made-better-with-azure/
but in reality the solution does not build successfully and I've resorted to just taking code from there and into my bot framework sample template....however, when it asks me to login through MS and I do, I am not able to proceed and it doesn't seem like that blog is using the AD B2C policies.
so how do you integrate AD B2C with Bot Framework? Is it possible to call /Account/SignIn URL from bot framework to authenticate the user? Afterwards, how would you capture the token and pass it to BotUserData?
You might want to take a look to the Facebook Auth sample to get an idea of a potential flow for the Auth scenario. For Azure AD, you need to do a similar flow.
Let's say your user send a "Login" message to your bot. The bot should respond with an auth URL and ask the user to login to the service using that URL. You can use the GetAuthorizationRequestURL method of ADAL for that.
Then you will have a Web API which will basically expose an endpoint that will be the reply URL of Azure AD. Once the users completes the login, a message will be posted to your Web API where you will be able to get the authorization code and perform the calls to get the Access Token. After that, you can just do the same they are doing in the Facebook Sample Web API which involves resuming the conversation with the Bot, sending a message with the access token (so it can be persisted in the PerUserInConversationData bag (check this line of code).
After that you have the access token available to perform any call that requires an access token.
Update
There are two new samples that you might want to take a look since they are implementing the workflow being discussed.
GraphBot from the BotBuilder repo.
AuthBot from Mat Velloso
Hope this helps.
Follow this tutorial for Bot side code development, i focus on configuration at B2C and Azure level here:
OAuth Connection
Client id
This is taken from the Application ID field in your B2C app's properties. It's the equivalent of a Microsoft app ID taken from any other AAD app registration.
Client secret
This is generated using the steps in this tutorial.
Select Keys and then click Generate key.
Select Save to view the key. Make note of the App key value. You use the value as the application secret in your application's code.
Use AAD V2 configuration in oAuth settings in bot channel registration - new oauth connection settings.
Fill the above details by following the steps and values we got from them.
Authorization/Token/Refresh URL
I followed on this one with
https://login.microsoftonline.com/tfp///oauth2/v2.0/authorize
for the Authorization URL and
https://login.microsoftonline.com/tfp///oauth2/v2.0/token
for the Token and Refresh URL's.
For I used the URL format (kyleorg.onmicrosoft.com) rather than the GUID format, but using the GUID also seems to work.
is the name of a user flow, like B2C_1_userflow. I created one with this tutorial.
Scopes
Using the scopes openid offline_access I am able to sign in successfully, but to my astonishment the token returned is empty.
Then I found this document which suggests using the client ID itself as a scope.
When I reuse the value from the Client id field in my Scopes field, a token is returned successfully and my bot is able to use the connection.
You can combine this with other scopes as needed, but for the sake of experimentation I highly recommend getting the simplest implementation to work first.
Let me know if these instructions work, and if they don't then we'll see if the difference lies in how we've set up our B2C apps.
As a bonus, I should mention that after you get a token you can paste it into https://jwt.ms/ to decode it and see if it recognized your B2C user correctly. Always refresh the page when pasting a new token to make sure it doesn't keep showing you the information from the last token.

Authenticate against Azure AD - ColdFusion Web Application

I'm developing a web application which will require users to login before they can use the app. I've looked into using the Azure Active Directory as the resource which I will authenticate against, however I'm having trouble understanding how to set things up.
I've logged into the Azure Portal and have created my Active Directory. I've also added my custom Web App to the Applications area, and provided the App Login URL and APP ID URI. Now I have been given my Client ID and Federation Metadata Document Url, but I have no idea where to go from here.
Could someone provide an example of how I take the username and password which they enter in my login form and submit that to Azure, receiving back a result which would indicate success or failure? Or is that not how it works?
Any help is greatly appreciated. I don't need any other information from the Active Directory other than confirmation that YES, the username and password matches and let them in.
The web application is coded in ColdFusion as per the client's request, and it is hosted on their server.
Thank you!!!
UPDATE
Using the directions found here https://msdn.microsoft.com/en-us/library/azure/dn645542.aspx I have been able to successfully request an authorization code by logging in using an Active Directory account. After I log in, the system redirects me back to my web application, and has a long url code variable, along with a url session_state variable. My question now is, what do I do with this information from my web app?

If you look at the picture in the link you mentioned, there are 6 steps.
What you have done so far is performed step 1 and 2. Now you would need to perform step 3 and 4 i.e. get an access token using the auth code you have received.
Please see the section titled Use the Authorization Code to Request an Access Token in the same link regarding how to do it.
As part of Step 4, you will get an access token back. It is essentially a JWT token. Not sure how you would do that in Cold Fusion, but you can simply decrypt/parse (for the lack of better words :)) this token to get information about the user.
Given that you only want to find out if the user is authenticated successfully, I believe if you have received the code you're good. You don't have to do anything more.

Authentication strategy between my chome extension and server

I'm in the process of building a Google Chrome extension, and have some questions about how to implement security into the application.
I need to access a couple of Google API's so am going to be using OAuth 2.0 for that. So basically from the extension I know which user is logged into the browser.
My extension then needs to get and post data to my (nodejs) API service. I want to ensure that the user requesting data is the same user that is logged into the browser. Is there any way of using the previous Google authentication process to also authenticate communications between the extension and my API? I dont really want the user to have to log in again, to access my API.
I'm sure I'm missing something simple, and I've not been able to find anything that fits this scenario
Follow the OpenID Connect auth flow and you will get an access_token and an id_token. The acess_token you will use to use to make authenticated requests to Google APIs as usual. The id_token will be used as authentication with requests to your server.
When the requests hit your server you will need to validate the token and you can then use the contents of the id_token to identify the user.
User wouldn't have to login on auth process provided if user is already logged in and you are using a web application flow (not chrome.identity APIs) but user would see the consent screen atleast the first time. However you can skip the account selector screen if you already know the email address by providing &login_hint= parameter.

Spotify API Authorization for cron job

I'm creating a node.js application that will update playlists (owned by an account in which I have credentials) daily. According to the Spotify documentation, to add tracks to a playlist (https://developer.spotify.com/web-api/add-tracks-to-playlist/), authorization must be supplied using oauth2.
I'm struggling to find a way to do this completely server side with no redirects/etc. It seems like if I can get a refresh token, I can just use that?
I've been looking at the spotify web api node module (https://github.com/thelinmichael/spotify-web-api-node), oauth.io, and the spotify api.
Any ideas would be appreciated! There is only one account that will have to be authenticated, so it could be hard-coded at least for now.
You've picked the correct authorization flow - Authorization Code, since you need an access token that's connected to the user who owns the playlists you're updating. This of course also gives you the ability to refresh the token whenever you need to. (The expiration time is one hour, but you don't need to refresh the access token until your application actually needs to use it.)
As a sidenote, the Client Credentials flow is meant for server to server communication that doesn't require a user's permission, e.g. to search, read a playlist, or retrieve new releases. The Implicit Grant flow is meant to be used in frontends, and doesn't allow you to refresh the token.
I'm struggling to find a way to do this completely server side with no redirects/etc. It seems like if I can get a refresh token, I can just use that?
Once you have the refresh token you can continue to use it to retrieve new access tokens, which can be done without any user interaction. You need to do some preparation work to retrieve the refresh token though.
Following the steps describing the Authorization Code flow, you first need to direct the playlist's owner to a URL on Spotify's account server.
The documentation contains the following example URL:
GET https://accounts.spotify.com/authorize/?client_id=5fe01282e44241328a84e7c5cc169165&response_type=code&redirect_uri=https%3A%2F%2Fexample.com%2Fcallback&scope=user-read-private%20user-read-email&state=34fFs29kd09
Simply replace the client_id and redirect_uri with your application's information. Also modify the scope parameter to match the scopes you need, which from my understanding of your use case is playlist-read-private,playlist-modify-private,playlist-read-collaborative since you want to be able to read and modify all of the user's playlists. Supplying state is not required.
Using spotify-web-api-node you can generate this URL using the createAuthorizeURL method, but since you're only doing this once it's unnecessary to write code for it.
Instead, simply open the URL in your browser.
If done successfully, you'll be taken through a little login dance where your application asks for your permission to read and modify your playlists. When this is completed, Spotify's account service will redirect the browser to your redirect_uri URL with a code query parameter included as described in step 3 in the Authorization Guide.
However, since you're only doing this once, it would be enough to start a webserver on your own machine, set your application's redirect_uri to your localhost, and complete the login flow. Have a look at web-api-auth-examples for a ready-made node.js application that fires up an express server and reads the authorization code.
Once you've got the code, you can trade it for an access token using cURL as it's done in step #4 in the Authorization Guide, or use the code in the web-api-auth-examples repository.
Finally, with the tokens retrieved (step #5), you can start to use the Web API with the access token, and get a new one when it expires using the request in step #7.
spotify-web-api-node has a helper method to refresh the token. Search the main documentation for the refreshAccessToken method.
This use case is slightly mentioned in the FAQ section of the Authorization Guide.
As you said, you need to obtain a refresh token using the authorization code flow. For that you will need to carry out the OAuth process using your user account, the client_id of the app you have registered, and the scopes you need (it will vary depending on whether the playlist is private or public). Then, take the refresh token you have obtained and the client secret key of your app, and you can obtain access tokens without the need of the login form.
