What Are Passkeys? A Simple Guide to Signing In Without a Password
If you have ever clicked “forgot password” on a site you only use twice a year, you already know the problem. Passwords are hard to remember, easy to reuse, and easy for scammers to steal. A newer sign-in method called a passkey is meant to fix that, and more and more websites and apps now offer it.
This guide explains what passkeys are in plain language, how they work, why they are harder to steal than passwords, and how to start using them without locking yourself out. It also covers the downsides, because passkeys are not perfect and not every site supports them yet.
What a Passkey Is, in Plain Language
A password replacement
A passkey is a way to sign in to a website or app without typing a password. According to the FIDO Alliance, the industry group behind the technology, a passkey is a type of credential tied to your account on a site or app, built to replace passwords. When you sign in, you approve the login the same way you unlock your phone or computer: with your fingerprint, your face, or your screen-lock PIN or pattern.
How it works without a shared secret
With a password, you and the website both know the same secret. That is the weakness, because anyone who tricks you into typing it, or breaks into the website’s records, gets the secret too.
A passkey works differently. When you create one, your device makes a matched pair of digital keys. The private key stays on your device. The website stores only the public key, which is useless on its own. When you sign in, your device proves it holds the private key, and you approve it with your fingerprint, face, or PIN. The FIDO Alliance says your biometric data stays on the device and is never sent to the website.
Where passkeys are stored
Passkeys are kept by a “passkey provider,” which is the service that creates, stores, and manages them. This can be your phone’s built-in password manager, your browser, or a separate password manager app. Many providers sync your passkeys across your own devices using encryption, so a passkey made on your phone can also work on your laptop.
Some passkeys are tied to one device and never leave it. Hardware security keys, the small physical devices you plug in or tap, work this way.
Why they are called phishing-resistant
Phishing is when a scammer sends a fake login page that looks real and gets you to type your password. A passkey is bound to the real website. A fake site cannot use it, because the passkey simply won’t work there, so you can’t be tricked into handing it over. That is why security agencies describe this kind of sign-in as phishing-resistant.
Why Passwords Are a Problem
The numbers
The FIDO Alliance’s 2026 report on passkeys surveyed 11,000 adults in 10 countries, including the US, UK, France, and Germany, in April 2026. It found that 33% of consumers had a confirmed compromise or breach notification in the past year, and that 47% were likely to abandon a purchase or a sign-in when they could not remember a password.
One caution: the FIDO Alliance promotes passkeys, and the figures come from a survey, so they are self-reported and come from a group with an interest in the topic. Treat them as indications, not as precise measurements. They do match what most people experience in daily life.
Reuse is the real danger
Many people reuse the same password on several accounts because remembering dozens is hard. If one site is breached, criminals try the same email and password on other sites. This is why a single leaked password can lead to several hacked accounts.
Why codes sent by text message are not enough
Many sites add a second step, such as a code sent by text message. That helps, but codes can still be tricked out of people on fake login pages. A passkey removes the code and the password from the process, which also removes what scammers rely on.
How Common Are Passkeys Now?
Awareness has jumped
The FIDO Alliance found that familiarity with passkeys rose from 39% in 2022 to 57% in 2024. In its 2026 report, 90% of consumers said they were aware of passkeys, and 75% said they had enabled them on at least some accounts. The report gives 74% for the US and 70% for Europe.
These numbers are high, and they may be higher than what you see in everyday life. The survey covered adults who regularly log in to online services, and it was conducted online. It also relied on people describing their own habits. Still, the direction is clear: big sites and apps now offer passkeys, and many prompt you to set one up.
The catch: not everywhere yet
Not every website or app supports passkeys. Banks, shops, and social networks vary. Even where passkeys are offered, a password usually remains as a backup. For now, most people will use a mix of passkeys and passwords.
How to Start Using Passkeys
The exact steps differ by site and device, so use this as a general guide.
Step 1: Make sure your device is secure
A passkey is approved with your screen lock, so your screen lock matters. Use a fingerprint, face unlock, or a PIN that is hard to guess. A short PIN that someone could watch you type in a public place is a weak point. Turn on automatic locking so your device locks when you step away.
Step 2: Choose where to keep your passkeys
Decide which passkey provider you want to use: your phone or computer’s built-in password manager, your browser, or a trusted third-party password manager. A provider that syncs across your devices is more convenient, because you won’t lose your passkeys if you replace a phone. Protect the account that controls that sync with a strong, unique password and its own extra security step.
Step 3: Add a passkey on one account at a time
Sign in to an account the usual way. Then look in the security or sign-in settings for an option such as “create a passkey” or “sign in with a passkey.” Follow the prompts, and approve with your fingerprint, face, or PIN. Start with an important account that you use often, such as your main email, since it is often the key to resetting everything else.
Step 4: Test it before relying on it
Sign out, then sign in again using the passkey. Check that it works on each device you use. If you use more than one device, check that the passkey is available on all of them.
Step 5: Keep a recovery option
Don’t delete your old sign-in method straight away. Make sure you have a way back into the account: a backup email, a recovery code, or a second device. Store recovery codes somewhere safe, such as a locked drawer, and not in a photo on your phone.
Passkey Problems and Questions Worth Knowing About
What if I lose my phone?
If your passkeys sync through your provider account, you can get them back on a new device by signing in to that provider account. That is why the security of the provider account is so important. If your passkeys are device-bound, such as on a hardware key, a lost key means you need another way in, which is why a second key or a recovery option matters.
In the FIDO Alliance’s workforce survey, 89% of organizations said they were confident they could restore access if a passkey is lost. Account recovery was still named as a barrier by 33%, so recovery is a real question for companies too.
What if someone knows my phone’s PIN?
This is a real risk. If a thief knows your screen-lock PIN and steals your unlocked or watched device, they may be able to approve sign-ins. Use a strong screen lock, keep your phone locked when it’s out of your hands, and be careful about who can see you enter your PIN in public.
Can I use passkeys on a computer that isn’t mine?
In many cases, yes. Many systems let you approve a sign-in on a computer by using your phone, for example by scanning a code. Check that the site and your devices support this before you rely on it. On a shared or public computer, be careful about what you sign in to.
Do passkeys make passwords disappear?
Not yet. Many sites keep passwords as a fallback. Over time, more sites may stop offering them, but for now, keep your remaining passwords strong and unique, ideally stored in a password manager. If you still use a password for an important account, turn on the extra security step too.
A quick checklist
- Use a strong screen lock, with automatic locking turned on.
- Pick one trusted passkey provider, and secure that account well.
- Add a passkey to your email first, then banking and shopping.
- Test the sign-in on each device you use.
- Save recovery codes somewhere safe and offline.
- Keep strong, unique passwords for sites that don’t offer passkeys.
- Check again in a few months, since more sites add support all the time.
The honest bottom line
Passkeys are not magic. They do not protect you if you give away your device and PIN, and not every site supports them. But they remove two of the biggest everyday risks: weak or reused passwords, and fake login pages. If you set up passkeys on your most important accounts first, such as email, banking, and your main shopping or social accounts, you’ll get most of the benefit with very little effort.
October is also a good month to do a small security check. Set up one passkey today, test it, and add the rest over the following weeks.
