For years, cybersecurity experts have warned that passwords are one of the weakest parts of online security. People reuse them across multiple accounts, create weak combinations that are easy to guess, or unknowingly hand them over through phishing scams. Even users who try to improve their security with two-factor authentication are not fully protected, especially when that second layer relies on SMS codes or weak recovery methods.
That is why passkeys are gaining serious momentum. Major companies like Apple, Google, and Microsoft have all adopted them, and more platforms are rolling them out every year.
The shift is significant enough that the UK's National Cyber Security Centre has publicly encouraged people to use passkeys wherever they are available. In its recent guidance, the NCSC explained that passkeys are more resistant to phishing attacks, easier for users to manage, and can help reduce one of the most common ways accounts are compromised.
This does not mean passwords are disappearing overnight, but it does mean the future of online authentication is changing.
Why Passwords Keep Failing
Passwords were never designed for the way we use the internet today. The average person now manages dozens, sometimes hundreds, of online accounts. Remembering unique passwords for every service is unrealistic, which is why many people recycle the same password across multiple websites.
That becomes a major problem when one company suffers a data breach. Attackers often take leaked credentials and test them across banking platforms, email providers, social media accounts, and cloud services. This technique, known as credential stuffing, remains incredibly effective because password reuse is still common.
Phishing is another major issue. Cybercriminals create fake login pages that look identical to real ones and trick users into entering their credentials. Once attackers capture that password, they can often bypass weaker forms of two-factor authentication as well.
What Are Passkeys?
Passkeys are a passwordless login method built on public key cryptography.
When you create a passkey for a website or app, your device generates two cryptographic keys. One is a public key that gets stored by the service. The other is a private key that stays securely stored on your device or inside your credential manager.
When you log in, your device proves that it owns the private key without ever revealing it. Instead of typing a password, you simply verify yourself using Face ID, your fingerprint, or your device PIN.
From the user perspective, it feels much simpler. From a cybersecurity perspective, it removes several common attack methods.
Why Passkeys Are More Secure
The biggest advantage of passkeys is that they are highly resistant to phishing attacks.
If you accidentally visit a fake website and try to log in, your passkey typically will not work because it is tied to the legitimate domain where it was originally created. There is no password for attackers to steal, reuse, or sell.
Passkeys also eliminate many risks tied to weak password habits. You do not have to remember them, write them down, or create predictable combinations based on birthdays, names, or repeated phrases.
This is one of the reasons security professionals increasingly see passkeys as a major improvement over traditional authentication methods.
They're Also Faster and Easier
Security tools often fail because they create too much friction. If something feels annoying, people avoid it.
Passkeys simplify the login experience. Instead of entering a password and then waiting for a verification code, you often unlock access in seconds using the same biometric authentication you already use to unlock your phone.
That convenience matters because better security tools only work when people are willing to adopt them consistently.
What Happens If You Get Compromised?
This is where people sometimes misunderstand passkeys.
They are significantly safer than passwords, but they are not magic.
If someone gains access to your unlocked phone, laptop, or password manager, they may be able to access accounts tied to your stored passkeys. A weak phone PIN or leaving devices unlocked can still create serious security risks.
Account recovery systems can also be a weak point. Many websites still allow password resets through email links, SMS codes, or customer support verification. If an attacker compromises your email account, they may bypass your passkey entirely through account recovery channels.
Malware remains another threat. Passkeys stop phishing attacks, but they do not stop malicious software from stealing browser sessions, logging activity, or exploiting already authenticated devices.
In other words, passkeys dramatically reduce one attack path, but they do not replace basic cybersecurity habits.
How to Stay Protected
Using passkeys should be part of a broader security strategy.
Keep your devices updated, use strong screen locks, secure your primary email account, review your account recovery settings, and avoid downloading suspicious files or software.
If a service does not offer passkeys yet, continue using a trusted password manager and enable two-factor authentication whenever possible.
The goal is not perfection. It is reducing the number of easy ways attackers can compromise your accounts.
Where Proton Pass Fits In
If you want a dedicated credential manager that supports both traditional passwords and passkeys, Proton Pass is one option worth considering.
It allows users to store passwords, generate secure credentials, manage passkeys, and sync them across devices without relying entirely on ecosystem-specific tools like Apple Passwords or Google Password Manager.
For users already in the Proton ecosystem, it can be a convenient privacy-focused option for managing both current passwords and future passkeys in one place.
Conclusion
Passkeys are not replacing every password tomorrow, but they represent one of the biggest improvements in consumer cybersecurity in years.
They make phishing dramatically harder, reduce password reuse, and simplify the login experience for everyday users. That combination of convenience and stronger protection is rare in cybersecurity.
As more platforms adopt them, expect passkeys to become a normal part of how people secure their digital lives.
