If you have recently opened the security settings of a Google, Microsoft, Apple, or another online account, you may have noticed an option called a passkey. The name sounds a little unusual at first, especially because there is no new password to create.

Instead, a passkey normally works through something you already use to unlock your device, such as a fingerprint, face recognition, PIN, or screen lock. The important part is what happens behind that simple prompt: the website and your device use cryptographic credentials rather than sending a traditional password during sign-in.

The technology is no longer limited to early adopters. The FIDO Alliance’s 2026 research reports that passkeys have reached billions of active uses worldwide.

So, what is a passkey?

A passkey is a sign-in credential based on FIDO standards. Instead of asking you to type a secret password into a website, the service can ask your device to prove that you have access to the credential associated with your account.

In everyday use, this can feel almost identical to unlocking your phone. You see a fingerprint prompt, use face recognition, or enter your device PIN, and the sign-in continues.

There is an important difference, though. Your fingerprint or face is not simply sent to the website as a password. For example, Google says biometric information used to unlock a passkey remains on the user’s device.

The FIDO Alliance passkey guide explains the underlying technology in more detail for anyone who wants to go beyond the simplified explanation.

Why are people talking about them now?

Passkeys have actually been around for a while. What has changed is the number of places where ordinary users can encounter them.

Major operating systems and browsers now support the technology, and more online services are adding passkey sign-in alongside traditional passwords.

According to the FIDO Alliance’s 2026 consumer research, 75% of surveyed consumers had enabled a passkey on at least one account. The study covered 11,000 adults across ten countries, so the figure should be understood in the context of that particular survey rather than as a measurement of every internet user.

That distinction matters because technology adoption can look very different from one country, platform, age group, or type of online service to another.

What problem are passkeys trying to solve?

The basic weakness of a password is fairly simple: the user has to create, remember, protect, and eventually replace a secret.

In practice, people sometimes reuse passwords, choose predictable combinations, save them in insecure places, or accidentally enter them on a fake website.

A passkey approaches the problem differently. The authentication process uses cryptographic credentials that are designed to resist common phishing techniques.

This is one reason the technology has attracted attention from security organizations. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) identifies FIDO/WebAuthn authentication as a widely available form of phishing-resistant authentication.

You can read the CISA guidance on phishing-resistant MFA for the technical security perspective.

Does this mean passwords are going away?

Not anytime soon.

Passwords remain a normal sign-in method on a huge number of websites. Even services that support passkeys may continue to offer passwords as an alternative or recovery method.

This means that adding a passkey to one account does not automatically solve password security everywhere else. Your older accounts still need attention.

A password manager can still be useful for services that do not support passkeys, while two-step verification can provide another layer of protection where it is available.

What happens if you lose your phone?

This is probably one of the first practical questions people have when they hear about passkeys.

The answer depends on the passkey provider and the type of passkey being used. Some passkeys can be securely synchronized between a user’s devices, while others can be tied more closely to a particular device or security key.

That is why setting up a passkey should not be treated as a one-click decision with no backup plan. It is worth checking the recovery options offered by the particular service before relying on a passkey as your only way back into an important account.

Google, for example, recommends creating passkeys only on devices that you personally own and use. Its support documentation also explains how passkeys can be removed if a device is lost.

Passkeys are not a reason to ignore basic security

It is easy to look at a new authentication method and assume the security problem has been solved completely. It has not.

Your main account still matters. If someone gains access to the account that manages your devices or credentials, the consequences can be serious. Device locks, software updates, recovery methods, and account security settings still deserve attention.

The same rule applies to shared computers. Creating a personal passkey on a computer that other people can unlock is not a good idea.

Should you create a passkey?

If a service you regularly use offers passkeys, it is reasonable to look at the option and understand how that particular service handles sign-in and account recovery.

There is no need to convert every account at once. Starting with an important personal account can be a more practical approach than changing everything in one afternoon.

Before creating one, check three things:

• which devices can use the passkey;
• how the service handles account recovery;
• what happens if your primary device is lost or replaced.

Google has a useful step-by-step guide to using passkeys with a Google Account .

A small change that may become less noticeable over time

The interesting thing about passkeys is that, if they work well, users may not think much about the technology at all.

There is no password to remember and no separate code to type in many sign-in situations. You simply unlock the device you already have.

That does not make every online account automatically secure, and it does not mean passwords will disappear overnight. It does mean that the familiar username-and-password routine is no longer the only practical model for signing in.

For anyone trying to make their everyday digital life a little easier, passkeys are worth understanding — even if you decide to keep using passwords for some accounts.
