Two Factor Authentication Importance Guide 2023

Why Two-factor Authentication is Important

The upward trend of cybercrimes continues to rise, as evidenced by the most recent Verizon report on mobile device security. The study reveals that 81% of cyberattacks exploit weak passwords, emphasizing the need for stronger security measures. While password managers remain a popular choice for securely storing passwords on mobile devices, today, we will explore two-factor authentication (2FA) as an additional and reliable option for safeguarding your data online.

Simplifying Two-factor Authentication (2FA): What it is and How it Works

Two-factor authentication requires users to verify their identity using two distinct methods to enhance security.

Upon accessing a digital platform, the most commonly used method for identification and authentication is the combination of a username and password. The username serves as our identifier, while the password verifies our identity.

In addition to using a password or PIN for authentication, which relies on something you know, you can also utilize something you possess, like a token or coordinate card, or something inherent to you, such as a fingerprint, iris scan, or facial recognition. This integration of methods is referred to as two-factor authentication or 2FA.

Simplifying Two Factor Authorization

The utilization of two-factor authentication is becoming more common in safeguarding email accounts, banking passwords, and access to social network profiles. Essentially, it provides an additional level of security. If desired, additional layers of protection could be incorporated, leading to the implementation of multi-factor authentication (MFA).

How to Perform Two-factor Authentication

Numerous approaches exist for implementing two-factor authentication. Below, we highlight the most widely recognized methods.

  1. ABANCA offers multiple methods for users to verify their identity, including physical objects like USB memory, security tokens, and temporary security codes that expire after a few minutes. These systems are used for signing operations conducted through electronic banking or accessing mobile banking using fingerprint authentication.
  2. An additional secret that is known only to you, such as a password, PIN, or the response to a personal question. Previously seen as a backup for forgotten passwords, it is now regarded as an additional layer of security.
  3. New cybersecurity measures utilizing biometric data such as fingerprints, iris scans, voice recognition, and facial recognition have emerged thanks to recent technological advancements. These measures are dependent on the user's specific mobile phone or tablet models.

Two-step Verification vs. Two-factor Authentication: Are They Similar?

Two-step verification and two-factor authentication are not identical security measures, as they have some differences. We will outline their distinctions for you.

While two-factor authentication combines something you know with something you have or are, two-step verification relies on two separate something you know factors, such as a password and a code delivered via SMS.

According to the National Institute of Cybersecurity (Incibe), two-step verification methods may be at higher risk due to the potential interception of the second factor, which is typically received via SMS.

Opt for two-factor authentication whenever possible, as it relies on external factors that are only accessible to the user and cannot be reached through the internet.

Numerous businesses are embracing this system, as seen in the recent implementation of two-factor authentication by the Fortnite video game. Incentivizing users with a special dance for their characters, the company aims to decrease the risk of potential fraud and enhance user security.

Understanding the Impact of the New Payment Law (PSD2) on Two-factor Authentication

The year 2023 saw the implementation of the Second Payment Services Directive (PSD2), a legislative framework that governs payment transactions and the accessibility of personal financial data. This directive has implications for individuals with bank accounts or cards, as well as for online businesses.

For customers, it involves bypassing mediators in online payment transactions, while for businesses, it entails providing tools for external parties to retrieve customer payment information. Strong Customer Authentication will be implemented to enforce this measure.

Two-factor authentication (SCA) will be required for the user to verify their identity. If the amount exceeds 30 euros, they will need to provide two forms of identification or log in to their bank account.

This article provides a comprehensive examination of the features of the recent payment law (PSD2), covering all the essential concepts, their significance, and potential consequences.

Tools for Two-factor Authentication

In response to the growing need for network data protection, major technology and software firms have developed a range of free and widely available two-factor authentication solutions. This reflects an awareness of the increasing importance of safeguarding data daily.

Using Google Authenticator for Added Security

Users of both Android and iOS can benefit from this Google service. The app enables you to obtain secure access codes for your accounts, even in situations where you have lost connectivity or mobile data.

Two-factor Authentication at Apple: A Quick Guide

This feature is built into the iOS system. When using multiple devices with this operating system, you can authorize access by receiving security codes on the devices you designate as trusted. No app installation is required, as you can enable this function through device settings with just a few easy steps.

Enhancing Security with Microsoft Authenticator

The primary goal of this app is to enhance the security measures for accessing Microsoft products and services, including Outlook, OneDrive, and Office. It is free to use and supports various authentication methods, such as fingerprint or facial recognition, depending on the user's mobile device.

To sum up, the increasing risk of cybercrimes emphasizes the vital need for strong security measures, as malicious actors often target weak passwords. As discussed in this article, two-factor authentication (2FA) is a dependable and necessary method for strengthening your online protection.

2FA is based on a two-step verification process that demands users to confirm their identity through two different methods. This can include a knowledge-based factor, like a password, along with a possession or inherent characteristic, such as a fingerprint or facial recognition. The flexibility of 2FA is apparent in its use across different platforms, ranging from email accounts to banking passwords and social media profiles.

The blog explores various ways to use 2FA, including physical devices such as USB drives and advanced biometric data. Highlighting the advantages of 2FA over two-step verification, the National Institute of Cybersecurity emphasizes its effectiveness in reducing risks related to intercepted SMS codes.

The online security environment is constantly changing, and the implementation of the Second Payment Services Directive (PSD2) in 2023 brings added importance to 2FA. As Strong Customer Authentication (SCA) becomes obligatory for transactions over 30 euros, the new payment regulations emphasize the crucial role of 2FA in safeguarding financial transactions.

In response to the increasing need for improved network data security, leading tech companies are providing free and easy-to-use 2FA solutions. With a range of options available, including Google Authenticator, Apple's integrated system, and Microsoft Authenticator, users can select the solution that best suits their needs for a more secure online experience.
