More details below. NET Core Identity. MSAL offers an essential set of primitives, helping you to work with tokens with few concise lines of code. Under the hood, MSAL takes care of many complex and high risk programming tasks that you would otherwise be required to code yourself.

Specifically, MSAL takes care of displaying authentication and consent UX when appropriate, selecting the appropriate protocol flows for the current scenario, emitting the correct authorization messages and handling the associated responses, negotiating policy driven authentication levels, taking advantage of device authentication features, storing tokens for later use and transparent renewal, and much more.

More on ADAL later in the post. Is it a web app or a web API? Say that you want to call the Microsoft Graph to gain access to the email messages of a user. For example, if I were to run that code and use my microsoft. After successful authentication, the user is promoted to grant consent for the permission requested, and some other permissions related to accessing personal information such as name, etc.

As soon as the user accepts, the call to AcquireTokenAsync finalizes the token acquisition flow and returns it along with other useful info in an AuthenticationResult. All you need to do is extract it via ar. AccessToken and include it in your API call. MSAL offers another primitive, AcquireTokenSilentAsync, which transparently inspects the cache to determine whether an access token with the required characteristics scopes, user, etc is already present or can be obtained without showing any UX to the user.

Azure AD issues powerful refresh tokens, which can often be used to silently obtain new access tokens even for new scopes or different organizations, and MSAL codifies all the logic to harness those features to minimize prompts. This means that from now on, whenever I need to call the mail API, I can simply call AcquireTokenSilentAsync as below and know that I am guaranteed to always get back a fresh access token; and if something goes wrong, for example of the user revoked consent to my app, I can always fall back on AcquireTokenAsync to prompt the user again.

This is the main MSAL usage pattern. All others are variations that account for differences among platforms, programming languages, application types and scenarios — but in essence, once you mastered this couple of calls you know how MSAL works. We are making MSAL available on multiple platforms. The concepts remain the same across the board, but they are exposed to you using the primitives and best practices that are typical of each of the targeted platforms.

We develop MSAL in the open, and we welcome community contributions. NET Standard targets. Thank you, Oren! NET is distributed via Nuget.

Use Microsoft Authentication Library for JavaScript to work with Azure Active Directory B2C

NET works on. NET Desktop 4. NET Standard 1. NET supports the development of both native apps desktop, console, mobile and web apps code behind of ASP. NET web apps, for example. Net WebApp, a. Net Core WebApp and a. Net WPF App.

You can find a sample demonstrating a simple SPA here. A sample for iOS can be found here. This approach has various advantages over the embedded browser control view used in ADAL: it allows SSO sharing between native apps and web apps accessed through the device browser, makes it possible to leverage SSL certificates on the device, and in general offers better security guarantees.

We still need to hear your feedback and retain the freedom to incorporate it, which means that we might still need to change the API surface before committing to it long term. Furthermore, both teh v2 protocol endpoint of Azure AD and B2C are still adding features that we believe must be part of a well-rounded SDK release, and although we already have a design for those, we need them to go through the same preview process as the functionality already available today.

To be concrete:.You can find high level conceptual documentations in the project README and workable samples inside the project code base. MSAL proposes a clean separation between public client applications and confidential client applications.

They are implemented as two separated classes, with different methods for different authentication scenarios. See this page for constraints of Username Password Flow. The current app is a middle-tier service which was called with a token representing an end user. The current app can use such token a. See detail docs here.

The current middle-tier app has no user interaction to obtain consent. See how to gain consent upfront for your middle-tier app from this article. Both PublicClientApplication and ConfidentialClientApplication have following methods inherited from their base class.

Token cache serialization in MSAL.NET

You typically do not need to initiate this base class, though. For PublicClientApplicationyou simply use None here. For ConfidentialClientApplicationit can be a string containing client secret, or an X certificate container in this form:.

Added in version 0. You may also override any of the following default claims:. If you requested user consent for multiple resources, here you will typically want to provide a subset of what you required in AuthCode. OAuth2 was designed mostly for singleton services, where tokens are always meant for the same resource and the only changes are in the scopes.

In AAD, tokens can be issued for multiple 3rd party resources. You can ask authorization code for multiple resources, but when you redeem it, the token is for only one intended recipient, called audience. So the developer need to specify a scope so that we can restrict the token to be issued for the corresponding audience. It is done either by finding a valid access token from cache, or by finding a valid refresh token from cache and then automatically use it to redeem a new access token.

This method will combine the cache empty and refresh error into one return value, None. If your app does not care about the exact token refresh error during token cache look-up, then this method is easier and recommended. This method will differentiate cache empty from token refresh error.

If your app cares the exact token refresh error during token cache look-up, then this method is suitable. None when there is simply no token in the cache.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

If you like what they're doing, please feed them! A library of components to easily integrate the Microsoft Authentication Library with Azure Active Directory in your React app quickly and reliably. The library focuses on flexibility, providing functionality to login, logout, and fetch the user details while maintaining access to the underlying MSAL library for advanced use. It was developed as a tool for the Open Source community to use and contribute to as they see fit.

Before beginning it is required to configure an instance of the MsalAuthProvider and give it three parameters:. The MsalAuthProvider is meant to be a singleton. There are known implications when multiple instances of MSAL are running at the same time.

The recommended approach is to instantiate the MsalAuthProvider in a separate file and import it when needed. Now you can import the authProvider and use it in combination with one of the authentication components. The options that get passed to the MsalAuthProvider are defined by the MSAL library, and are described in more detail in the configuration options documentation. Below is the total set of configurable options that are supported currently in the config. When instantiating an instance of the MsalAuthProvider the authentication parameters passed will become the default parameters used when authenticating and fetching or refreshing tokens.

It is possible to change the default parameters later by executing the setAuthenticationParameters method on the MsalAuthProvider. The set of options that are supported for the Msal. The options parameter defines settings related to how the authentication provider processes authentication operations provided by the MSAL library.

LoginType is an enum with two options for Popup or Redirect authentication. This parameter is optional and will default to Popup if not provided. The tokenRefreshUri allows you to set a separate page to load only when tokens are being refreshed. When MSAL attempts to refresh a token, it will reload the page in an iframe.

This option allows you to inform MSAL of a specific page it can load in the iframe. It is best practice to use a blank HTML file so as to prevent all your site scripts and contents from loading multiple times.

At any time after instantiating the MsalAuthProvider the login type can be changed using the setProviderOptions method.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.
