Tips for creating a secure authentication system in an AngularJS application!

As a novice in the world of angularjs...

After going through the documentation and completing a tutorial, I decided to experiment on my own which has helped me grasp things better.

Now, I'm looking into creating a secure authentication system.

The process is quite simple: I will outline the operations that my code will carry out:

I have a basic form with fields for username and password input.

Once the user enters their details and hits ENTER,

An ajax request is triggered, and based on the response JSON received, I can determine if the user is recognized or not.

What I aim to achieve now is to maintain the logged-in state of the visitor across different views of the application.

While researching online, I found examples where some set a variable ($scope.isLogged = true) while others used cookies. However, both javascript variables and cookies are vulnerable to manipulation using tools like firebug.

...and now, onto the main question:

Therefore, do you have any suggestions for implementing a secure authentication system in an angularjs application?

When it comes to authorization in angularjs, it's important to remember that the user has ultimate control over the browser environment. This means that any security measures put in place can potentially be tampered with by the user. While there are encryption libraries available for local data storage, they may not provide the level of security you're seeking.

Instead, the best approach is to handle authorization on the server side using traditional session methods. By relying on server-side authentication and checking sessions, your application can ensure that only authenticated users have access to certain features or content. The frontend application simply serves as a visual indicator for the user's logged-in status.

While you may have already discovered a solution, I recently developed an authentication system that I am integrating into my Angular application.

Upon initialization, the app is registered with an ActiveSession status set to false. It then verifies if the browser contains a cookie with both a token and a userId.

If the necessary information is present, the app checks the validity of the token and userId on the server, updating the token on both the server and locally. Each user is assigned a unique server-generated token.

If the required information is not found, the app displays a login form where users can input their credentials. Upon successful validation, a new token is requested from the server and stored locally.

This token enables persistent login functionality, allowing users to remain logged in for three weeks or through browser page refreshes.

Thank you for considering this approach.

It has been three months since I first posed this question.

I am excited to share my favorite method for handling user authentication in a web application using AngularJS.

Although fdreger's response remains exceptional!

In AngularJS, it is impossible to authorize anything as the user has complete control of the execution environment (specifically, the browser).

For your AngularJS application, being "logged in" or "logged out" is simply a visual cue for the user.

Thus, my approach can be summarized as follows:

1) Add additional information about each route by binding to it.

$routeProvider.when('/login', { 
    templateUrl: 'partials/login.html', controller: 'loginCtrl', isFree: true
});

2) Utilize a service to manage user data and their authentication status.

services.factory('User', [function() {
    return {
        isLogged: false,
        username: ''
    };
}]);

3) Whenever a user tries to access a new route, verify if they have permission to do so.

$root.$on('$routeChangeStart', function(event, currRoute, prevRoute){
    // prevRoute.isFree indicates whether the route is accessible to all users or only registered ones.
    // User.isLogged indicates if the user is logged in.
})

I have also discussed this approach in more detail on my blog, available at users authentication with angularjs.

It's important to note that data on the client-side can always be altered or tampered with.

However, if session IDs are secure and precautions like linking session tokens with the client's IP address are in place, there shouldn't be a major issue.

Another option is to encrypt cookies, but this should be done server-side for optimal security.

If you need guidance on how to encrypt your cookies, refer to the documentation of your server-side framework (e.g., http://expressjs.com/api.html#res.cookie for Express.js).

Understanding the server side and database aspect is crucial.

User credentials must be securely stored, typically in a server-side database backend.

An ideal setup for maximum security involves a backend membership system that manages sessions in a database table linked to member data with encrypted passwords. This system should also offer a RESTful interface for API integration.

One highly recommended script is Amember, which has proven effective and cost-efficient. While there are many other options available, Amember's PHP framework allows for easy development of APIs for Angular HTTP calls.

Javascript frameworks are valuable, but it's essential not to neglect the importance of understanding database and backend operations. Balance is key!
