Understanding Passkeys: What They Are and How They Work

A passkey is a modern type of login credential that replaces traditional passwords. Instead of typing a password, you use something you have or something you are—like your fingerprint, face recognition, or a PIN number stored on your device. Passkeys work through a technology called public-key cryptography, which uses two linked codes: one that's public and one that stays private on your device.

When you create a passkey for an online account, your device generates these two codes. The website or service keeps only the public code. When you log in, your device uses the private code to prove you're the real account owner—without ever sharing that private code over the internet. This is fundamentally different from passwords, which are the same every time you use them and get sent to servers where they can potentially be stolen.

Several major technology companies have adopted passkeys, including Apple, Google, and Microsoft. As of 2024, major platforms like Gmail, iCloud, WhatsApp, eBay, and PayPal have rolled out passkey options for their users. Banks and financial institutions are gradually introducing them as well. According to research from the FIDO Alliance, passkey usage grew by over 200% between 2022 and 2023 as more services made them available.

Passkeys use several verification methods depending on what your device supports. Biometric verification—fingerprints and facial recognition—is the most common. If your device doesn't have biometric sensors, you can use a PIN or pattern unlock code. Some services also allow you to use a passkey from one device to log into another device, using Bluetooth or scanning a QR code.

Practical Takeaway: A passkey is a replacement for passwords that uses your device's built-in security features like fingerprint or face recognition. The technology keeps your private verification code on your device and never sends it to the website.

Key Differences Between Passkeys and Passwords

Traditional passwords have remained largely unchanged since the early days of the internet, despite significant security problems. When you create a password, you memorize or store it somewhere. You type this same password every time you log in. The website stores your password in its database. If that database gets breached, hackers obtain your password—which they might also use on other sites if you reused it. According to the 2023 Verizon Data Breach Investigations Report, weak or reused passwords were a factor in 34% of breaches involving credentials.

Passkeys eliminate several of these vulnerabilities. First, you don't need to remember them. Your device stores the passkey locally and handles the login process automatically. Second, each passkey is unique to both you and the specific website—a compromised passkey from one site cannot be used on another. Third, the private code that proves your identity never leaves your device. A hacker who steals a website's database gets only the public code, which is useless without the private code locked in your device.

Passkeys are resistant to phishing attacks in a way passwords are not. When a scammer creates a fake login page that looks identical to the real one, they can trick you into typing your password. A passkey, however, works through cryptography that verifies you're on the legitimate website. Your device will simply not create a valid passkey response for a fake site, even if it looks perfectly authentic.

The setup process differs too. Creating a password is immediate—you type it in and you're done. Creating a passkey takes slightly longer because you typically need to verify your identity using biometrics or a PIN. However, logging in with a passkey is usually faster than passwords. On a phone, it might be a single fingerprint tap. On a computer, you might scan a QR code with your phone or use Windows Hello facial recognition.

Practical Takeaway: Passkeys are stored on your device rather than memorized, are unique to each website, never transmit your private verification code, and protect against phishing. These differences make them significantly more secure than traditional passwords.

Step-by-Step Process for Creating a Passkey

The process for creating a passkey varies slightly depending on the website and your device, but the general flow is consistent. First, you log into your account using your current login method—this might be your existing password or another verification method. Look for settings, security, or account options, usually found in a menu or account dashboard.

Most services have a section labeled "Security" or "Sign-in & security" where you'll find the option to add a passkey. Click or tap this option. The website will guide you through the creation process. You may need to verify your identity again using your current password, a code sent to your email, or a verification code from an authenticator app. This extra step ensures that only the real account owner can add a new passkey.

Next, your device will prompt you to create the passkey using your preferred method. If you're on an iPhone or iPad, you'll see a prompt to use Face ID or Touch ID. On an Android phone, you might use fingerprint, face unlock, or your screen lock PIN. On a Windows computer, you could use Windows Hello (face or fingerprint), a PIN, or biometric data if your computer has a reader. On a Mac, you would use Face ID or Touch ID.

After you complete the biometric or PIN verification, the system generates your passkey pair and stores it securely on your device. The website receives only the public part. Most services then show a confirmation screen. Write down any recovery codes or backup options presented to you—these are important if you lose access to your device. Keep these codes in a safe place, like a secure password manager or a physical safe.

Finally, test your passkey by logging out and logging back in. Navigate to the login page and enter your username or email. Instead of a password prompt, you should see an option to use your passkey. Verify your identity using your biometric or PIN, and you should be logged back in. This confirms that your passkey was created correctly.

Practical Takeaway: Creating a passkey involves logging in with your current method, finding the security settings, verifying your identity, using your device's biometric or PIN to create the passkey, and testing the login process.

Managing Multiple Passkeys Across Devices

Many people use multiple devices—perhaps a phone, tablet, and computer. When you create a passkey on one device, it typically works only on that device because the private code stays locked in that specific device's secure storage. To log in on another device, you have several options depending on the website and your devices.

Cross-device signing is a method supported by major platforms. When you try to log in on a device that doesn't have your passkey—for example, attempting to log into Gmail on a borrowed computer—the website can send a notification to your phone. You approve the login on your phone using your fingerprint or PIN, and you're signed in on the computer. You never move your passkey; your phone simply verifies that you're the account owner.

Creating the same passkey on multiple devices is another approach. If you own multiple devices that you use regularly, you can create separate passkeys for each one. Log into the same account on each device and go through the passkey creation process for each. Most services allow you to create multiple passkeys—one for your phone, one for your computer, one for your tablet. Each one functions independently, but they're all registered to your account.

Synced passkeys represent a newer approach. Apple, Google, and Microsoft now sync passkeys across their ecosystems. If you create a passkey on your iPhone, it automatically syncs to your iPad and Mac through iCloud's secure system. Similarly, Google syncs passkeys across Android devices and computers through your Google account. This means you don't need to create separate passkeys for each device—they're automatically there.

Recovery and backup codes become more important when you use multiple devices. When you create your first passkey, save any backup codes or recovery options the service provides. If you lose access to a device, these codes let you verify your identity and regain access to your account. Store these codes separately from your devices—perhaps in a physical notebook in a safe place or in a password manager that isn't stored on any single device.

Practical Takeaway: You can use passkeys across multiple devices through cross-device verification, creating separate passkeys for each device, or using synced passkeys through your ecosystem. Save backup codes in case you lose device access.
