Example

Refer the example here: https://github.com/NewtonJoshua/Azure-ADB2C-Angularjs-sample

Azure AD B2C

Azure AD B2C is a cloud identity management solution for your web and mobile applications. It is a highly available global service that scales to hundreds of millions of identities.

Mobile app - ADAL plugin

Mobile app implementation uses ADAL Cordova Plugin Patch For B2C. This is a chopped version of Active Directory Authentication Library (ADAL) plugin for Apache Cordova apps, cordova-plugin-ms-adal that works with Azure AD B2C. The original cordova-plugin-ms-adal plugin provides easy to use authentication functionality for your Apache Cordova apps by taking advantage of Active Directory.

Find the angularjs/ionicframework example below

Install the dependencies:

cordova plugin add https://github.com/jospete/azure-activedirectory-library-for-cordova --save

bower install angular-jwt --save

Let us have a LoginController

.controller('LoginController', function($scope, $state, $ionicPopup, jwtHelper, AdalService) {

    $scope.login = function(){
        AdalService.login().then(function(authResponse) {
        displayUserDetails(getUserData(authResponse));
    });

    $scope.logout = AdalService.logout;

    // Decode decode the token and diaplay the user details
    function getUserData(response) {
        var user = {};
        user.token = response.access_token || response.token;
        var data = jwtHelper.decodeToken(user.token);
        user.expires_in = new Date(response.expires * 1000) || response.expiresOn;
        user.name = data.name;
        user.email = data.emails ? data.emails[0] : '';
        user.id = data.oid;
        return user;
    };

    function displayUserDetails(user) {
        $scope.user = user;
        $ionicPopup.alert({
            title: user.name,
            template: '<b>Email:</b> ' + user.email + '<br> <b>Id:</b> <code>' + user.id + '</code>'
        });
    }

});

Enter the Azure AD B2C settings here

.value('settings', {
    // ADAL-B2C configuration
    adalB2C: {
        tenantName: 'Enter your tenant name',
        clientId: 'Enter your client id',
        policy: 'Enter your policy name'
    }
});

And here is the adal.service that implements Azure AD B2C using ADAL plugin

angular .module('azureADB2C') .service('AdalService', function($q, $http, settings) {

    var extraQueryParams = 'nux=1';
    var userId = null;
    var redirectUri = 'https://login.microsoftonline.com/tfp/oauth2/nativeclient';
    var authority = 'https://login.microsoftonline.com/' + settings.adalB2C.tenantName;
    var resourceUri = 'https://graph.windows.net';

    this.login = function() {
        var deferredLoginResponse = $q.defer();
        var authContext = new Microsoft.ADAL.AuthenticationContext(authority);
        // Attempt to authorize user silently
        authContext.acquireTokenSilentAsync(resourceUri, settings.adalB2C.clientId, userId, redirectUri, settings.adalB2C.policy)
            .then(function(authResponse) {
                deferredLoginResponse.resolve(authResponse);
            }, function() {
                // We require user credentials so triggers authentication dialog
                authContext.acquireTokenAsync(resourceUri, settings.adalB2C.clientId, redirectUri, userId, extraQueryParams, settings.adalB2C.policy)
                    .then(function(authResponse) {
                        deferredLoginResponse.resolve(authResponse);
                    }, function(err) {
                        deferredLoginResponse.reject(err);
                    });
            });
        return deferredLoginResponse.promise;
    };

    this.logout = function() {
        // Step1: clear cache
        var authContext = new Microsoft.ADAL.AuthenticationContext(authority);
        authContext.tokenCache.clear();

        // Step2: make XmlHttpRequest pointing to the sign out url
        return $http.post(authority + '/oauth2/logout?post_logout_redirect_uri=' + redirectUri);
    };

});
