Passkeys are not the end of passwords - they're the next evolution of trust

Passkeys are emerging as a more secure and user-friendly alternative to traditional passwords by reducing reliance on human memory and limiting common attack methods such as phishing and credential theft.

According to Wayne Yan, the future of authentication lies not in eliminating passwords entirely, but in building trust systems that balance strong security with ease of use.

Every few years, the cybersecurity industry declares the death of the password.

Yet passwords persist because they solve a simple problem: proving who you are.

The challenge is that they do so increasingly poorly in a world where data breaches, phishing attacks, and credential theft have become everyday realities.

Passkeys represent the latest attempt to solve this problem, and unlike many previous efforts, they have the potential to fundamentally improve both security and user experience.

But it would be a mistake to view them as the final answer.

The real innovation behind passkeys is not simply that they are more secure than passwords.

It is that they shift the burden away from human memory.

For decades, organisations have expected people to create strong passwords, remember them, avoid reusing them, and update them regularly.

Unsurprisingly, most people have failed at this task, and not because they are careless, but because it is unrealistic.

“For years, we asked users to compensate for weaknesses in authentication systems by creating stronger passwords and remembering more of them. Passkeys flip that model. Instead of relying on people to be security experts, they use technology to make secure behaviour the easiest behaviour,” says Wayne Yan, Technology Director at Dariel.

Passkeys recognise an important truth about cybersecurity: if security relies on perfect human behaviour, it will eventually fail.

Reducing Reliance on Passwords

By replacing passwords with device-based authentication such as biometrics or cryptographic keys, passkeys remove many of the vulnerabilities that attackers have relied on for years.

Credential stuffing, password reuse, and many phishing attacks become significantly more difficult because there is no password for an attacker to steal in the traditional sense.

That does not mean passkeys are risk-free.

Every security control introduces new dependencies.

A forgotten password can usually be reset.

A lost phone, damaged security key, or inaccessible biometric device presents a different challenge altogether.

Organisations will need to think carefully about recovery processes, identity verification, and business continuity when passkeys inevitably fail or become unavailable.

There is also a tendency to overestimate the security of any new technology.

Biometric systems have improved dramatically, but they are not infallible.

Hardware devices can be lost, stolen, or damaged.

No authentication mechanism is immune to attack.

The goal is not perfection; it is making attacks sufficiently difficult, expensive, and impractical that criminals move on to easier targets.

“Passkeys won't eliminate cybercrime, but they do remove some of the most common attack paths available to criminals today. By reducing reliance on passwords, organisations can significantly lower their exposure to phishing, credential theft, and password reuse attacks,” Yan explains.

Security and Human Behaviour

Perhaps the most important lesson is that cybersecurity has never been a technology problem alone.

It is a human problem.

The history of authentication is a story of balancing security against convenience.

Passwords tipped too far towards convenience.

Traditional multi-factor authentication often tipped too far towards friction.

Passkeys may represent the first widely adopted approach that genuinely improves both.

This shift is particularly important as organisations continue to grapple with security fatigue.

Every additional security step creates friction, and friction inevitably drives workarounds.

The most successful security controls are often the ones users barely notice.

“The biggest challenge in cybersecurity has never been technology—it's human behaviour. Passkeys are exciting because they acknowledge that reality. They reduce the need for users to remember dozens of passwords and make secure authentication simpler and more natural,” says Yan.

The Future of Authentication

The future of authentication will not be defined by whether passkeys replace passwords.

It will be defined by whether organisations can build trust systems that are secure enough to protect users while remaining simple enough for people to embrace.

Passkeys are not the end of the journey.

They are simply the next step towards a future where security works with human behaviour rather than against it.

As Yan concludes:

“The future of authentication isn't about finding a perfect security solution. It's about creating systems that are secure enough to protect organisations while remaining simple enough for people to use consistently. Passkeys are one of the strongest steps we've taken in that direction.”
