Nowadays every business works upon large amount of sensitive data and user’ personal information. That’s why Multifactor Authentication(MFA) has become very important for these businesses. It has many layers for security which makes it highly protected and no unauthorized person can get access to this data. As Multifactor Authentication System provides an extra level of security other than the password hence they have become a must for apps related to finance, payments, banking and enterprise apps requiring the viewing or retraction of the data from the cloud.

Looking at extensive benefits of MFA, a professional Mobile App Development Company must be contacted to build the entire MFA system for any app. Now it is not an option but a necessity if you want to protect your data and prevent unauthorized login attempts. In this article, we will discuss about the concept of MFAs and explain the four ways by which you can implement Multifactor Authentication in your mobile app. We will also tell you the whole process required for MFA. First let’s talk about what is Multifactor Authentication System.

Multifactor Authentication System (MFA):
Multifactor Authentication or MFA is the system by which we add an extra layer of security in the login process which ensures that users are giving more than just one piece of evidence for their identification required for login. It generally requires a combination of something which user knows, like passwords, PINs, question-answers, or something which the user has, like phone, cards or something biological like Fingerprint scan or Retina Scan.
You can contact App Development Services which understand these and can implement these for your app. Right now there are generally four ways by which you can implement MFAs into your Mobile Application. Let’s discuss about each of these ways and the process MFAs take the users to go through while logging in.

Methods to Implement Multifactor Authentication in a Mobile App

Using Time Based OTP
OTP involves the creation of one-time password from shared secret key and the present timestamp with the help of cryptographic function. OTP has the enrollment and login process.
The detailed process is:-

Enrollment Process:-

  • First of all, users login in to the app using their username and password.
  • If the username and passwords are found valid then the next stage is to enable the two-factor authentication.
  • After that a shared key is requested which can be either text based or QR code.
  • This key is stored by the app which has implemented OTP like Google Authenticator.
  • After that the two factor authentication is enabled.

Login process:-

  • In this process, first the User logs into the app.
  • If their username and password are valid then they are taken to a form where they have to write or enter one-time code generated with Google Authenticator.
  • After that the server verifies that the code is valid and authenticates the user.

Using SMS:
This process of multifactor application using SMS also has steps of enrollment and login.

Enrollment Process:-

  • First the users log into an application with their username and password.
  • After that they have to enter their active phone number.
  • After that a unique one-time code is generated on app server and sent to the user’s phone number.
  • After that they have to enter the code in the app thus enabling multifactor authentication.

Login Process:-

  • First, users have to log into the application with their username and password.
  • After that a unique one-time code is generated on app server and sent to the user’s phone number.
  • After that the user has to enter the code in the app.
  • If it is valid then the user gets authenticated and the session gets initiated.

Using an E-Mail:

  • First of all, user logs in an application using their username and password.
  • After that a unique one-time code is generated on app server and sent to the user’s email id.
  • The users then take the code from their email and enter into the app.
  • If it is valid then user is authenticated and session gets started.

Using Push Notifications:

  • first of all, the users log into the application using their userid and password.
  • Generally, push notification system works with applications like Auth Guardian. After the details are entered, push notification is then sent by Guardian app to your app.
  • The users get a notification of login request.
  • At the backend, this included the data like the application name, browser and OS used while making request, the exact location and date of request generating is being made.
  • After that the user accepts the request they have got through push notification and gets logged in.

Conclusion
We have just discussed various ways to implement the Multifactor Authentication System. Although these steps look simple but they involve writing complex programming codes. Hence you need a support of a professional Mobile App Creator which is expert in providing these kind of services. Adding each layer of security requires more work for the users as well as for the developers. No user would like to repeat the multiple steps hence multifactor authentication system should be implemented properly after taking due care. Overall we can say that looking at its benefits, multifactor authentication system is a must in login to any mobile app which involves sensitive data to prevent data breach attempts from hackers.
