The Essential Guide to Automated 2FA & MFA Testing

Security is one of the biggest concerns in today’s digital world. The traditional ways of using passwords to interact with online accounts are no longer sufficient. Two widely embraced security measures are Two-Factor Authentication (2FA) and Multi-Factor Authentication (MFA), which are designed to protect one’s personal and professional information.

In this blog, we will provide an overview for both 2FA and MFA, as well as go over how you can overcome common challenges when it comes to automating 2FA and MFA testing.

What is Two-Factor Authentication (2FA) Testing?

Two-Factor Authentication (2FA) testing ensures the reliability of the security process that requires two different forms of verification before granting access to an account. This added layer of security significantly reduces the likelihood of unauthorized access. Even if someone manages to steal your password, they won’t have the second factor needed to log in.

 Typically, this involves:

1. Something You Know: A password or PIN.
2. Something You Have: A temporary code sent to your mobile device — often via SMS testing — generated by an authenticator app, or provided by a software/hardware token.

What is Multi-Factor Authentication (MFA)Testing ?

Multi-Factor Authentication (MFA) testing takes the concept of testing 2FA a step further by ensuring the required two or more verification methods from different categories are functioning properly. 

These methods can include:

1. Something You Know: Your password.
2. Something You Have: A smartphone app, software/hardware token, or SMS code.
3. Something You Are: Biometric data such as fingerprints or facial recognition.

Examples of 2FA & MFA Testing

Critical features that would need to be tested in order to ensure their security would include: 

OTP-Based Authentication

• Text based SMS OTP
• Audio based On-Call OTP
• Timer based OTP’s – Needs to be tested with various Network Carriers
• Email based OTP
• WhatsApp based Code

Microsoft Authenticator App-Based Authentication

• Enter displayed number in AUT
• OTP code generated once for every 30 seconds

Soft Token-Based Authentication

• External Apps like RSA

Biometrics-Based Authentication

1. Touch ID
2. Face ID

Adding to the complexity of testing these security features, end users may also use different devices for applications and authentications. For example, if you were to transfer funds on a banking application, you need to be able to seamlessly launch the bank application on Device 1 (desktop browser) and receive the SMS OTP on Device 2 (mobile device).

Bottom Line

Security is one of the most critical aspects of a digital application. One must ensure that the authentication functionality is tested thoroughly. Given the complexity of authentication features and how end users can access the application with one or multiple devices, testing can be very challenging. 

Perfecto addresses these challenges by providing support with both hardware and software perspectives for seamless, automated 2FA and MFA testing.
