In today’s digital age, authenticating users has become crucial for any organization. With the rise of cybercrime and fraud, companies must take stringent measures to ensure that their users are who they claim to be. Unfortunately, traditional password-based authentication is no longer enough to guarantee the security of your users’ accounts. As technology evolves, hackers have become more advanced and sophisticated, making it easier to break into user accounts.

To address this challenge, companies are adopting multi-layered approaches to authentication. These approaches not only authenticate users but also help to mitigate fraud by detecting and preventing unauthorized access. This blog will discuss each of these five layers in detail, along with their benefits and limitations. By the end of this blog, you will better understand how multi-layered authentication can help you secure your users’ accounts and mitigate fraud.

1. Password-based authentication

Password-based authentication is the most common form of user authentication and is the first layer in multi-layered authentication. The user provides their username and password, and if the credentials are correct, the user gains access to the system or application. Password-based authentication is a simple and convenient way to authenticate users and is widely used in many organizations. However, it has some limitations that make it less secure than other forms of authentication.

One of the most significant drawbacks of password-based authentication is that users tend to use weak passwords that are easy to guess or crack. Many users also reuse the same password for multiple accounts, which makes them vulnerable to credential-stuffing attacks. Credential stuffing attacks occur when an attacker uses stolen usernames and passwords from one website to access other websites where the user has used the same credentials. This is why users must use complex and unique passwords for each account.

Another limitation of password-based authentication is that passwords can be easily stolen or intercepted. Hackers can use various methods to steal passwords, such as phishing, keylogging, and brute force attacks. Once the hacker has access to the user’s password, they can gain access to the user’s account and perform fraudulent activities. 

2. Two-factor authentication

Two-factor authentication (2FA) is the next layer that can be used to improve the security of user accounts. In traditional password-based authentication, users only need to enter their username and password to gain access to their accounts. However, with 2FA, users must provide an additional credential, usually a one-time code or a biometric verification, to gain access to their accounts.

The additional layer of security provided by 2FA makes it relatively difficult for hackers to gain unauthorized access to user accounts. Even if a hacker obtains a user’s password, they would still need the authenticating procedures to gain access to the account. This significantly reduces the risk of fraud and unauthorized access to user accounts.

Different 2FA methods can be used, including SMS-based authentication, app-based authentication, hardware tokens, and biometric authentication. SMS-based authentication is the most commonly used 2FA method, where users receive a one-time code via SMS to their registered phone number. On the other hand, app-based authentication uses a mobile app to generate the one-time code.

3. Behavioral biometrics

Traditional biometric authentication, such as fingerprints and facial recognition, are used to verify the identity of a user. On the other hand, behavioral biometrics uses machine learning algorithms to analyze users’ behavior patterns to identify anomalies that could indicate fraudulent activity. This type of authentication is based on the fact that every individual has unique characteristics in their behavioral patterns, such as typing speed, mouse movement, and even how they hold their device.

Behavioral biometrics is a passive authentication method, meaning users don’t have to perform specific actions to authenticate themselves. The system continuously monitors user behavior in real time and compares it to previous patterns. If there is a significant deviation from the norm, the system can flag it as a potential fraud attempt and prompt additional verification.

Additionally, the benefits of using behavioral biometrics for authentication are significant. Since the system analyzes continuous user behavior patterns, hackers can’t replicate these behaviors, making it difficult to bypass this layer of authentication. 

4. Device recognition

Device recognition is an essential layer of authentication that can help businesses prevent unauthorized access and mitigate fraud. In today’s digital age, where people use multiple devices to access their accounts, identifying and verifying a user’s device becomes crucial. Device recognition uses various techniques to identify and verify the device, such as fingerprinting, geolocation, IP address, and device ID.

One of the benefits of device recognition is that it can help businesses detect and prevent account takeover attacks. Account takeover attacks occur when a hacker gains unauthorized access to a user’s account, often through compromised login credentials. Device recognition can help businesses identify whether a user is logging in from a familiar device or location. If not, the business can ask for additional authentication measures, such as a one-time password or biometric authentication.

Another benefit of device recognition is that it can help businesses prevent fraud. By identifying the device a user is logging in from, companies can detect whether the device has been associated with fraudulent activities. If the device has a history of fraudulent activities, the business can deny access to the account or ask for additional authentication measures.

5. Risk-based authentication

Risk-based authentication is the fifth and final layer companies can use to secure their users’ accounts. This approach analyzes various factors to determine the risk associated with a particular user and adjusts the authentication requirements accordingly. By using this approach, companies can reduce the burden on users and improve the overall user experience while maintaining their accounts’ security.

The verdict

Authentication is a critical aspect of user security in today’s digital age. That said, traditional password-based authentication is no longer sufficient to protect users’ accounts from hackers and fraudsters. Consequently, companies must adopt multi-layered authentication approaches to enhance user security and mitigate fraud.
