Can Biometrics Eventually Replace Passwords
Can Biometrics Eventually Replace Passwords?
Today's users place a high premium on security. Whether it's our home or our phones, we're accustomed to having the most robust security measures in place. Additionally, as cyberattacks continue to plague us, we may seek new defenses. Google, Apple, and other tech giants are also equipping their devices with robust security features to safeguard user data.
Each of us has witnessed the evolution of security technology over the last two decades. We've come a long way since the simple four-digit code, pattern lock, passwords, and now biometrics.
As biometrics such as fingerprints and facial characteristics become more prevalent, they are occasionally used in place of passwords. Yes, you may no longer require a password to access a particular service. Rather than that, you can gain access by pressing your finger against a scanner on your phone. Sounds alluring and convenient, right? In some ways, it is. However, can biometrics truly take the place of passwords? What if they begin to leak? Let us examine all of the possible outcomes and concerns.
Passwords vs. Biometrics
To be fair, passwords are unlikely to be phased out anytime soon. It is still the de facto standard method of connecting to and securing networks, accounts, and devices. Biometrics, on the other hand, have been used in place of or in addition to passwords. Numerous services may even adopt password-free technology. Nonetheless, millions of bank customers can now conduct smaller transactions without completing additional steps.
The Benefits of Passwords
1. Passwords are a cost-effective choice
One of the primary reasons passwords outrank biometrics is their cost-effectiveness. How?
On the one hand, a password is a collection of secret characters that must be matched using a code and is simply stored securely on the device.
On the other hand, biometric security factors such as fingerprint scanning and facial recognition necessitate the use of a sophisticated set of sensors and pattern detection techniques. Adding these security features to your devices will cost you more than password authentication.
2. Wider compatibility
Consider a keypad phone. It will be incapable of utilizing any type of fingerprint authentication. Furthermore, not everyone owns a smartphone, which means that biometrics will not be compatible with all devices.
By comparison, passwords are an ideal solution because they can be added to any device, making them a universal authenticator.
3. Ensures confidentiality
When you use a fingerprint or face lock to unlock your phone, it compares the obtained pattern to the stored pattern on your machine. Due to the fact that these patterns contain a significant amount of information that can be used to identify the individual, losing them to a cyberattack will be a significant risk.
On the other hand, a password does not contain any personal information that could be used to identify you. It's a simple string of characters that could have occurred to anyone. This feature of passwords ensures their security.
The Advantages of Biometrics
1. Faster. One of the primary advantages of biometrics such as fingerprints, facial recognition, and iris scanning over passwords is their speed. These allow you to unlock your devices in a matter of seconds, whereas passwords take a little longer. And who knows whether or not you remember your password.
2. There is no problem in remembering. You do not need to remember anything with biometrics. All that is required is to run a scan. When it comes to passwords, you may find yourself juggling dozens of passwords for each account.
3. There is no match. Due to the fact that everyone's fingerprints, facial patterns, and iris structure are unique, there is no way that the biometrics of two or more individuals could be identical. On the other hand, 1234 is an easy-to-remember password that many people can use to save time.
All of this indicates that both passwords and biometrics have their advantages and disadvantages. This is why your smartphones and laptops have both a biometric and a password-based login system. Users can choose between the two based on their comfort level or combine them for convenience.
What if biometrics completely replaces the need for passwords?
For the sake of argument, let us suppose that passwords are completely replaced by biometrics. It will undoubtedly provide advantages and convenience.
Biometrics, on the other hand, will amplify certain risks. Due to the fact that your biometric data is stored on company servers, there is a possibility that it will be compromised. In other instances, your connection may be intercepted, and the data you exchange (including biometrics) may be stolen or altered. Apart from utilizing a Virtual Private Network to safeguard your connections, you may need to take additional precautions. While a VPN will protect your data online, it will not guarantee that it will be kept secure by others. For example, it would be preferable to store biometrics locally, i.e. on users' devices, rather than through external sources.
After all, passwords are easily changed. You cannot, however, change your fingerprints.
