Passwords can be difficult to remember, especially when each account requires something different. While it’s easy to reuse them, one stolen password leaves all your accounts vulnerable. Passkeys are a simpler, more secure way to sign in without a standard password. The first thing you need to do to make the switch is learn how this technology works on different devices.
What Are Passkeys and How Do They Work?
A passkey is a secure digital credential kept on a device. You can sign in using the same method you use to unlock that device, such as a fingerprint, face recognition or PIN.
A passkey consists of two interconnected keys. The website or app gets your public key, while your private key stays on your device. When you log on, the service issues a request that can only be approved with the private key. This authenticates you without sending a password.
This arrangement provides better defense against server-side data breaches, as websites don’t hold a secret that attackers may steal and reuse. That protection matters because compromised credentials were the starting point of a breach in 22% of the breaches evaluated in Verizon’s 2025 research. Even if someone has the public key, they cannot access your account without the private key.
How Passkeys Protect Against Phishing and Credential Theft
Passkeys are increasingly secure because they eliminate the shared secret that makes passwords vulnerable to attack. There is no password for an attacker to guess, steal or buy after a data breach. The private key stays on the user’s device, so only the public key is exposed to the website or app.
It is quite useful for detecting phishing attacks that typically redirect users to a fake login page. Phishing accounts for 79% of account takeover attacks, indicating how often thieves exploit people into unwittingly giving up their passwords.
Passkeys do not require users to type or share any credentials. Each is associated with the website or app they were designed for. If a user visits a fake version of that site, the domain will not match, and the passkey will not authenticate the login. A hacker also cannot fool someone into surrendering a passkey over an email, text message or phone call.
Even if the user is interacting with a plausible phishing page, the private key remains safe on the device. This architecture stopped some credential theft attacks before an attacker could get in.
Why Passkeys Are Critical for Professionals
A compromised personal account poses security risks for you, while a compromised business account can endanger a whole firm. Professionals will often utilize their own login to access customer information, financial data and internal systems. If an attacker stole such credentials, they may potentially impersonate the account owner or reveal sensitive data.
The impact can extend beyond the initial security issue. Workers could be locked out of essential equipment while the corporation investigates the intrusion and rebuilds its systems. That downtime might mean delayed client service and lost income. In a 2024 study, 31% of respondents identified business disruption as a key threat to their operations.
Passkeys mitigate this danger by replacing reusable passwords with device-specific credentials. Employees don’t have to enter passwords that can be stolen via phishing pages or insecure storage. Each passkey is likewise locked to the website or application for which it was designed.
Adopting passkeys can thereby safeguard more than a single login. This can help firms maintain client trust and reduce the chances of a stolen credential disrupting day-to day operations. Switching is perhaps most helpful for those who need access to sensitive information across multiple devices.
Three Ways to Use Passkeys Across Your Devices
Passkeys can be stored and used in several ways. The right method depends on the devices you own and how you prefer to access your accounts.
1. Smartphones
A passkey authenticator can be an iPhone or an Android phone. When you log in, you approve the request with Face ID, a fingerprint or your screen lock PIN. The biometric data never leaves your device. iCloud Keychain or Google Password Manager will also sync across additional devices on the same account. And that’s what makes cellphones a convenient option for regular use. Google confirmed that Android passkeys can work with a fingerprint, facial scan or screen lock.
2. Computers
You can log into passkeys using the built-in security of Windows and macOS devices. Windows Hello provides facial recognition, fingerprint scanning and a device PIN. Mac users can utilize Touch ID or their computer password to approve logins. This option gives you a fast experience if you use the same computer regularly for work or personal accounts.
You can also sign in on a computer using a smartphone passkey. Usually, the site will display a QR code that you scan with your phone, and then you verify your identity.
3. Hardware Security Keys
A hardware security key is a physical device, separate from your computer, that connects via USB, NFC or another compatible method. It can store passkeys without requiring a phone or a cloud account. Services usually require a security key that is FIDO2 compliant, according to Google.
It can be useful for people who manage sensitive accounts or who constantly switch between platforms. Since the physical key is required to log in, users should store a spare key or an alternative recovery method in case the primary key is lost.
How to Create and Use Passkeys
The setup process varies slightly by platform, but most services walk you through it once you are signed in. Before you start, update the device and set a secure screen lock technique. Only generate passkeys on devices that you own and control.
Google Accounts and Chrome
For a Google Account, generate a passkey in your account’s Security settings. Under “How you sign in to Google,” pick Passkeys and security keys. Tap “Create a passkey” and prove your identity with your fingerprint, face scan or screen lock.
Android might automatically produce a passkey for the device’s Google Account. You may also manage other saved passkeys in Google Password Manager. In Chrome, choose the three-dot menu > “Passwords and autofill” > “Google Password Manager.” Saved passkeys may be accessible on other devices when you are signed into the same Google Account. Google also enables users to remove account passkeys from its sign in settings.
If a website accepts passkeys, log in as you normally would, then look for an option to set one up in the account’s security settings. Chrome will ask you where you want to keep it.
Apple Devices
If you have an iPhone, iPad or Mac, begin by enabling iCloud Passwords and Keychain. On your iPhone or iPad, go to Settings > [your name] > iCloud. Click “Passwords & Keychain” and enable synchronization. Mac users can go into System Settings, choose their name and find “Passwords & Keychain” under iCloud.
Now, log in to a supported site or app and find its security settings. Create or save a passkey, then approve it with Face ID, Touch ID or the device passcode. The passkey will sync via iCloud Keychain and be available on other Apple devices signed in to the same Apple Account.
Users will be able to view and delete saved passkeys in the Passwords app. They may have been included under Passwords in Settings or under System Settings in previous versions of the system.
Microsoft Windows
If the option is there, Windows users can create a passkey when they visit a supported website or app. Choose “Create a passkey,” save it on your Windows device and confirm the request with Windows Hello. This can be facial recognition, a fingerprint or a PIN, depending on how the computer is set up.
To see the passkeys you have stored locally, go to Settings, choose “Accounts,” then “Passkeys.” This section lists the sites and apps that have saved credentials. Choose a passkey to view the options for managing or deleting it from the device.
Next time you sign in, select the passkey option and complete the Windows Security question. Windows Hello authenticates the presence of the approved user without sending the PIN or biometric information to the website.
The State of Passkey Adoption
Passkeys are still not supported by all websites and apps, but availability is growing. The FIDO Alliance’s global research showed that awareness of passkeys grew 50%, from 39% to 57%, between 2022 and 2024.
The organization is helping shepherd that change by creating standards that enable passkeys to work across major platforms. You can take them gradually for the time being. Begin with the high-value accounts you already have passkeys for, such as your primary email and financial services accounts. As other platforms add compatibility, you can continue converting other logins and reduce your reliance on traditional passwords.
A More Secure Future Is Here
Passkeys make logins more secure without adding more stages to the process. They protect accounts from typical credential assaults, and they do it without forcing the user to memorize another password. Start with one high-value account, then continue the rollout as passkey support grows.
