In a digital world plagued by security breaches, weak passwords, and identity theft, biometrics are emerging as the frontrunner in the race for better cybersecurity. Fingerprints, facial recognition, voice patterns, and even behavioral traits are being hailed as the keys to a more secure and seamless digital experience. However, the path to replacing passwords is not without its share of obstacles, risks, and ethical dilemmas.
For decades, passwords have been the primary method of authentication. However, their vulnerabilities are increasingly evident. A 2023 Verizon report revealed that weak or stolen passwords accounted for more than 80% of hacking incidents. “The password was never designed for the modern internet. It’s time we move to solutions that fit the needs of a connected world,” Sundar Pichai, CEO of Alphabet, said in 2024.
The biometrics revolution
Biometric authentication promises a significant leap forward. Unlike passwords, biometric traits are inherently unique to each individual, making them difficult to replicate. “Biometric authentication is a game-changer,” says Stephan Jou, Senior Director of Security Analytics at OpenText, a Canadian information company specializing in enterprise information management (EIM) software that is transitioning to biometrics. “It’s not just about replacing passwords; it’s about creating a system that’s inherently more secure and far less burdensome for users.”
Companies like Apple, Google, and Microsoft are leading the race. Apple’s Passkeys, introduced in 2022, use cryptographic keys tied to biometric data, ensuring sensitive information never leaves the user’s device. Microsoft’s Windows Hello integrates biometrics into its enterprise tools, while Google has expanded biometric authentication across Android and cloud services.
Why biometrics are not perfect
But biometrics are not a silver bullet. Jou identifies several challenges that must be addressed before passwords can be fully retired. “Implementing biometric systems isn’t cheap. Organizations need to invest in hardware, software development, and integration with existing systems,” he explains. “The cost of implementation is a barrier, but it’s coming down. Most smartphones are already equipped with biometric capabilities, which reduces the need for separate devices. Standards like Passkeys make it easier to integrate these systems,” adds Rick Killpack, Global Director of Products and Strategy at OpenText.
Biometric systems must perform reliably across diverse conditions. Changes in a person’s appearance—such as aging or wearing masks—can affect accuracy. “A fingerprint scanner that struggles with wet hands or a facial recognition system that fails in low light undermines user confidence.” Biometric data is immutable; once compromised, it cannot be replaced. Centralized databases storing such data become lucrative targets for hackers. “Biometric data should never leave the user’s device,” says Killpack. “That’s why protocols like Apple’s Secure Enclave are so important. They ensure that sensitive information stays encrypted and localized,” adds Jou.
The threat of spoofing
Biometric systems are not immune to attack. Deepfake technology, which uses AI to create realistic replicas of faces, voices, and gestures, poses a serious threat. “In 2023, researchers demonstrated that some facial recognition systems could be fooled by deepfake-generated images. As attackers become more sophisticated, biometric systems need to stay one step ahead,” Jou notes. Liveness detection is therefore critical. This technology ensures that the biometric input comes from a living person, not a fake representation.
Behavioral biometrics—analyzing user patterns such as typing rhythms or mouse movements—add a layer of continuous authentication. When combined with multi-factor authentication, these measures enhance security without compromising convenience. “They’re always running in the background, adding an extra layer of security that’s hard for attackers to bypass,” says Jou.
A passwordless future
Analysts predict that by 2030, traditional passwords will be largely obsolete in developed economies. “Biometrics won’t kill passwords entirely. But they’ll make them increasingly irrelevant. Passwords will become a fallback, not the primary means of authentication,” says Jou.
As biometric authentication becomes the norm, the stakes rise. Companies must also navigate the ethical implications of collecting and storing biometric data while staying ahead of evolving cyber threats. “We need to ensure that this transition happens responsibly,” warns Jou.
