What is the entire history of mobile authentication and how did it become a reality?

The history of mobile authentication is a fascinating journey that reflects the evolution of technology and security concerns. To tell you a little bit more about the tale, here’s the history of mobile authentication in a concise manner:

1. Early Days of Mobile Devices (1980s-1990s)

The advent of mobile phones started in the 1980s where these devices were primarily used for voice communication. The security used was minimal and it often involved simple PIN codes that prevented unauthorized use. 

After that the SMS (Short Message Service) service started which was introduced in the 1990. Consequently, the need for authentication started to increase but the associated methods remained basic.

2. Introduction of Smartphones and Basic Security (Early 2000s)

With the introduction of early smartphones, mobile devices began to become a lot more sensitive to data. After this, PIN codes and alphanumeric passwords became a standard way for accessing smartphones and authentication. These methods were simple but provided a basic level of security.

3. Enhanced Security Features (Mid-2000s to Early 2010s)

After the introduction of Android in the year 2008, the pattern lock offered a much user-friendly way of securing devices. This was when services started to implement 2FA which was often used for SMS or email . This enhanced security for online accounts that were accessed using mobile devices.

4. Biometric Authentication (Mid-2010s)

In the year 2012, Apple came with iPhone 5S which was popularized for its fingerprint scanning (Touch ID) feature. This became the beginning of biometric authentication for unlocking smartphones and authenticating purchases. Some time after with a lot of skepticism initially, facial recognition became more widespread with the advancements in camera technology and AI.

5. Advanced Biometrics and Multi-Factor Authentication (Late 2010s to Present)

After much simpler versions of authentication, the smartphone world was introduced to multiple advanced authentication features. For instance, Samsung Galaxy Note 7 came with Iris Scanning, multi-factor authentication, and behavioral patterns of the user aka behavioral biometrics.

6. Integration with Other Technologies

Later on came the time of NFC and Bluetooth. This used proximity based authentication for various applications for payments and smart locks. In fact, wearables started to play a role in the authentication process by often pairing it with smartphones.

7. Future Trends and Developments

If we start talking about future trends, improving the accuracy and security of biometric systems will be laid back on advanced AI and machine learning. In fact, we have blockchain and other decentralized technologies that are being explored for secure and user-controlled authentication. This became a reality because of the different regulatory influence of GDPR, CCPA, and other privacy regulations that are shaping authentication data.

What is two factor authentication?

Two-factor authentication is a security process in which users provide two different authentication factors in order to verify themselves. The method is used to better protect the user’s credentials and resources the user can access. The 2FA authentication is much more secure than single-factor authentication (SFA) which only involves one factor, typically a password or a passcode.

Key component of 2FA:

  • Something You Know: This is typically a password or PIN. It’s a piece of information that the user should know and is expected to keep secret.
  • Something You Have: It could be any device, smart card, or a security token. For example, the OTP generated by any service.
  • Something You Are (less common in basic 2FA setups): This comprises biometrics like fingerprint, facial recognition, or iris scan. This is more commonly used for multi-factor authentication.

How 2 Factor Authentication Works?

  • First Step: In this step, the user enter their username and password.
  • Second Step: In this step, the user is required to provide the second factor such as entering a code.

Some Common 2FA Methods

  • SMS-Based Codes: It is a code that is sent to the user via text message.
  • Authenticator Apps: Google Authenticator app, Authy, or any other similar application generate these time based codes.
  • Hardware Tokens: These are physical devices that generate a code at the push of a button.
  • Push Notifications: It is a notification that is sent to a pre-authenticated device which can approve, disapprove, or deny.

Limitations and Considerations

  • Dependence on Secondary Device: If the user loses access to their smartphone or token, this can lock them out of their account.
  • Vulnerability to Certain Attacks: SMS-based 2 factor authentication are vulnerable to swapping and other forms of interception.
  • User Convenience: 2FA can be an inconvenience if the user frequently switches devices.

What is multi-factor authentication?

Multi-factor authentication (MFA) in many ways is similar to two factor authentication, however, it does add a layer of security. It is a security system that requires more than one method of authentication from independent categories or credentials. This is done to verify the user's identity for a login or other transaction. MFA aims to combine two or more distinct factors in order to ensure a high level of security. This can be a lot more challenging for unauthorized persons in order to gain access to a device, network, or database.

Key Elements of MFA:

  • Passwords, PINs, or Secret Questions
  • Device that generate or receive verification code
  • Biometric verification like fingerprint scans, facial recognition, voice recognition, etc.
  • Location-based services
  • Gestures or actions to interact in a similar manner with a device

How MFA Works?

  • Layered Defense: By using multiple authentication methods from different categories, MFA creates a layered defense, thereby making it a lot more difficult for unauthorized persons to access the target such as physical location, computing device, network, or database.
  • Process: The user first provides a password and then they are prompted to enter the code that their phone has received. This can also be carried out via a fingerprint scanner.

Advantages of MFA

  • Enhanced Security: Higher security in comparison to single-factor or two-factor authentication methods.
  • Reduced Risk of Compromise: Just in case, if one factor is compromised then also it is difficult to breach it because of additional authentication requirements.
  • Compliance with Regulations: Multiple industries or government entities require MFA for enhanced security especially where sensitive data.

Common MFA Methods

  • SMS or Email Codes
  • Authenticator Apps
  • Biometric Tokens
  • Location-Based Authentication

Some of the best MFA apps are:

  • 2FAS
  • Aegis Authenticator
  • Duo Mobile
  • Google Authenticator

Challenges and Considerations

  • It can be seen as inconvenient or time-consuming by some users.
  • Losing the authentication device means no access.
  • MFA enhances security considering SMSs can be intercepted and can also become a victim to SIM swapping attacks.

Key Differences Between 2FA and MFA

  • Complexity: MFA is typically more complex, therefore, requires a much wider range of authentication factors.
  • Security Level: MFA generally provides higher security due to the use of multiple authentication methods.
  • User Experience: 2FA is much quicker and simpler for the user, thereby, providing MFA provides more robust security at the cost of potential inconvenience of the user.

What are the different processes associated with two-factor authentication and multi-factor authentication?

Here's a table that outlines the different processes associated with Two-Factor Authentication (2FA) and Multi-Factor Authentication (MFA):

Process Step Two-Factor Authentication (2FA) Multi-Factor Authentication (MFA)
1. Initial Login User enters username and password. User enters username and password.
2. Authentication request System prompts for a second factor after initial login. System prompts for additional factors (more than two) after initial login.
3. Generation and Delivery of Factors - SMS or Email: Code sent to user’s device.
- Authenticator App: User generates code.
- Hardware Token: User uses a device to generate a code.
- Something You Have: Code via SMS, email, app, or hardware token.
- Something You Are: Biometric data (fingerprint, facial recognition).
- Somewhere You Are: Location-based authentication.
- Something You Do: Behavioral biometrics (typing pattern).
4. User Submission of Factors User enters the second factor (code or biometric). User provides all required factors (code, biometric, location, etc.).
5. Verification and Access System verifies the second factor and grants access. System verifies each factor; access is granted only after all are validated.
