Almost two years ago I had written a tutorial around 2FA in a Node. While the previous tutorial is still valid, it uses a less popular library to accomplish the task. Before getting too far ahead of ourselves, I wanted to point out that time-based one-time passwords TOTP are not the only way to accomplish 2FA in modern web applications. The above commands will create a new Node. They will also install Express. The totp-secret function will generate a secret token to be saved in an application like Google Authenticator.
The totp-generate function will generate a time-based one-time password TOTP based on the secret token, and the totp-validate function will validate that the TOTP is valid for a given secret and is not expired. The Speakeasy package is very easy to use.
The above example is very basic. After it is provided to the user during generation, it should never leave the backend application again. In typical scenarios, tokens only exist for 30 seconds at a time. The expiration times can be extended through the validation process. The validation process takes the secret token, which should come from the database directly, and the expiring token that the user provides.
If the token is valid and not expired, true will be returned back to the client. Be careful when adjusting the window value as it is typically the norm to only allow one TOTP every 30 seconds. Allowing tokens to be valid 90 minutes in the future may not be a good idea.
You just saw how to add a second factor of authentication to your web applications with time-based one-time passwords. Now that you have secret tokens being generated, why not implement your own application for generating TOTP tokens? Nic Raboy is an advocate of modern web and mobile development technologies.

From Theory to Practice: Adding Two-Factor Authentication to Node.js
How to get a list of phone numbers that have opted out of receiving SMS messages. You can send a message directly to a phone number, or you can send a message to multiple phone numbers at once by subscribing those phone numbers to a topic and sending your message to the topic. In this example, you use a series of Node. The Node. SNS client class:. Install Node. For more information about installing Node. Create a shared configurations file with your user credentials.
Use Amazon SNS to specify preferences for SMS messaging, such as how your deliveries are optimized for cost or for reliable deliveryyour monthly spending limit, how message deliveries are logged, and whether to subscribe to daily SMS usage reports. In this example, use a Node. Create a Node. Configure the SDK as previously shown. Create an object containing the parameters for getting SMS attributes, including the names of the individual attributes to get.
This example gets the DefaultSMSType attribute, which controls whether SMS messages are sent as Promotionalwhich optimizes message delivery to incur the lowest cost, or as Transactionalwhich optimizes message delivery to achieve the highest reliability.
SNS client class. Then handle the response in the promise callback. This sample code can be found here on GitHub. Create an object containing the parameters for setting SMS attributes, including the names of the individual attributes to set and the values to set for each. This example sets the DefaultSMSType attribute to Transactionalwhich optimizes message delivery to achieve the highest reliability.
Create an object containing the phone number to check as a parameter. This example sets the PhoneNumber parameter to specify the phone number to check.Not too long ago I wrote about authenticating within a Node.
The basis of the example is around authenticating via a username and password and receiving a JWT for every future request against the API. Before we get invested into the code, we should probably come up with a plan.
The user will first authenticate using a username and password. If we try to access a protected endpoint while not authenticated, we will get an error.
Adding two-factor authentication to our web application is not as difficult as it sounds.
While I recommend you read and understand the other tutorial, you can see the source code here:. The above code should exist in an app. Within the same directory as the app. The code and above commands will get us to where we had left off in the previous tutorial.
We will be using no database in this example, but instead mock data. Before we start doing some heavy lifting, we need to clean up our code a bit. However, they will both exist as HTTP headers. For this reason, we should do the following:. Notice in the above we have created a separate getBearerToken method that we then use within our middleware.
We are also altering the logic of our middleware a bit.
We are now checking if authorized exists on the decodedToken object and is true. This value will be true if 2FA is disabled or if 2FA happened successfully.
In the above endpoint function we are assuming that our database data has a data element called 2fa that is a boolean. This indicates whether or not 2FA is enabled or not for this particular user. If the username and password are valid then we can create a JWT with the authorization status.
The status will be the opposite of whatever the 2fa value is. If 2FA is true or otherwise enabled, then we are not yet authorized. In the above endpoint, we again assume a mock user and this mock data has a time-based one-time password TOTP secret. Assuming the token generated from the authentication endpoint is valid, we check to see if the passed one-time password is valid using the 2FA library we had downloaded. If the password is valid, we update the authorized property and return a new token.
While not necessary, if we wanted to generate 2FA secrets or numeric time-based passwords, we could use the following:. You just saw how to add an extra layer of protection for users of your API. With two-factor authentication your users will have to authenticate with username and password, followed by a time-based one-time password. This password is generated using a shared secret which can be maintained in applications such as Google Authenticator or Authy. The full source code to this project can be downloaded here.

Toggle navigation The Polyglot Developer.Yes, you would definitely need your user-base to be more secure than just having a password based authentication.
By the end of this post, you will be able to create an application that has a simple login and registration feature along with the 2-Factor Authentication. After having the above mentioned tools being installed, the next step would be to create the API services for the application.
For creating the API services, we would be using the minimal and flexible web framework for Node. We will now create a few API services, with app. For the simplicity of learning process, separation of concerns is followed for the scaffolding of the application. Registration service : The registration of a user in the application would be just to add the username and password to the userObject as well as to reset the already existing userObject information.
Since the login and registration modules are made just for the demonstration purpose, the application will support only a single user login and registration.
TFA service : This service is to provide a feature for the setup of the two factor authentication along with the verification of the T-OTP code generated by Google Authenticator. Thus we have setup the server side code for our web application.
Now the next step would be to create a simple Angular 7 application to consume these created services.
For creating an Angular 7 application, we should first install Angular globally. The guards generated here are the CanActivate guards. The login-service would include the HTTP calls to the services created at back-end. The login-guard would not allow the user to navigate to login or registration page if the user is already logged-in.
Login Component : This is a simple component to accept the username, password and the AuthCode if TFA is enabled from the user and to verify it with the back-end services. If the user information is valid, then the user will be navigated to the HomeComponent.
Once the user is registered and logged in with the username and password, the user will be provided with an option to enable or disable the Two-Factor Authentication in the HomeComponent. The AuthCode will be displayed on time basis in the app and the same code should be entered in order to verify and enable TFA for the userObject.
Two-Factor Authentication with Node.js
If you have reached till this length of the post, then you have successfully learnt of how to easily integrate the Two-Factor Authentication in your Angular 7 application.
For any debugging process, you may look at the console of either the front-end application or the back-end application. Humans Ways in Which Machines Learn.Snippets Generated by using postman.
Postman Collection. You should use either one to authenticate your login. You can use this if apiKey is not being used. Please do not disclose this to anyone. Comments: Keep number in International format with country code. For International customers, sender name depends on country to country basis. For simple English, you can give value as text or for non-English messages, give value as unicode. System default is num. Comments: Type of the OTP token to be generated. Comments: Maximum time to allow your users to regenerate OTP.
If you have set 60 seconds, then user cannot request OTP again for next 60 seconds. System default is false. Name of the medium to deliver OTP to. You can deliver on 2 medium simultaneously.

Is your feature request related to a problem? Please describe. When choosing the "Backup directory" in settings, one has to write out the path by hand. This creates a multitude of problems:. It would be helpful to have a comprehensive documentation of the endpoints to help configure Authelia correctly in real life environments.
However that is a rather large undertaking. We could have a table for documentation and then add links in this table where it links to. But the questions would be. Hi, I followed the example site and managed to get the "secret" page working with 2FA setup on my website. However, to protect the admin site, I found this ReadTheDocs articlebut it doesn't seem to work. Is this procedure still the current way to make 2FA work on the admin site?
Using this, when I go to t. There should be an option to edit the color of the account or at least the logo of the website appears next to the name. That would be much easier and readable. To separate out the generated profiles from the non-generated one. Unfortunately, everytime we run the aws-mfa tool, it removes that comment.
Add documentation on what callback actually is. For most people it's clear to be a function but even then it would be good to document what to expect exactly.
Hello there, would it be possible to add the response to all function calls? Otherwise I am unable to determine if for example an SMS message was sent.
