What Passkeys Are and How They Work

Passkeys represent a newer approach to logging into online accounts. Instead of remembering passwords, passkeys use a combination of something you have (like your phone or computer) and something you are (like your fingerprint or face). This method is based on technology called FIDO2, which stands for Fast Identity Online 2.

When you set up a passkey, your device creates two linked codes. One code stays on your device—this is called a private key. The other code gets stored by the service you're logging into, like a bank or email provider—this is called a public key. These two codes work together like a lock and key. When you try to log in, your device proves it has the matching private key, and you confirm your identity using your fingerprint, face, or a PIN. The service never actually sees your private key, which makes this method more secure than traditional passwords.

Passkeys work across many devices. If you set up a passkey on your phone, you may be able to use it to log into accounts on your computer as well. Different companies handle this slightly differently. Some services sync your passkeys across your devices through cloud storage, while others keep passkeys on individual devices and allow you to verify your identity across devices when needed.

The main advantage of passkeys is that they're harder to steal than passwords. Hackers can't guess them, and they can't be compromised through data breaches the way passwords can. You also don't have to remember them. This eliminates common problems like using the same password across multiple sites or writing passwords down where they might be found.

Practical Takeaway: Passkeys replace passwords by using your device and biometric information (fingerprint or face) to prove who you are. Unlike passwords, they're unique to each service and can't be guessed or reused across accounts.

Setting Up Your First Passkey

Setting up a passkey is a straightforward process that most people can complete in just a few minutes. The exact steps vary slightly depending on which service you're using and which device you're on, but the general process is similar across platforms.

First, you'll go to your account settings on the website or app where you want to create a passkey. Look for security settings or account settings. Most services now have a section specifically for passkeys or "passwordless sign-in." You may see it labeled as "Passkeys," "Security Keys," "Biometric Login," or something similar. Once you find the right section, there should be a button that says something like "Create Passkey," "Add Passkey," or "Set Up Passkey."

When you click that button, the service will ask you to verify your identity using your existing password or another verification method. This is a safety measure to make sure you're really the account holder. After you verify, your device will ask you to confirm your identity using your fingerprint, face recognition, or a PIN code. This creates the connection between your identity and the passkey.

Your device will then generate the passkey and send part of it to the service. You'll usually see a confirmation message saying something like "Passkey created successfully" or "You can now sign in with this passkey." Some services allow you to give your passkey a name so you can identify it later, which is helpful if you create passkeys on multiple devices.

After setup, you should test your new passkey by signing out and signing back in. When you try to log in, instead of typing a password, you'll see an option to sign in with your passkey. Click that option, and your device will ask you to use your fingerprint, face, or PIN to confirm it's really you. Once you confirm, you'll be logged in.

Practical Takeaway: Creating a passkey takes less than five minutes. Go to your account's security settings, create the passkey, confirm your identity with your fingerprint or face, and test it by signing out and back in.

Understanding Device and Sync Options

Passkeys can be stored in different places depending on how you want to use them. Understanding these options helps you choose the setup that works best for your situation. The main categories are local device storage and synced passkeys.

Local device storage means your passkey lives only on one device—like your phone or laptop. If you want to log into an account from that device, you use the passkey stored there. The advantage is that your passkey never leaves that device, so it's very secure. The disadvantage is that you can only use it on that one device. If you get a new phone or want to log in from a computer, you can't use that passkey. You'd need to create new passkeys on each device or keep using a password as a backup.

Synced passkeys work across multiple devices you own. Services like Google, Apple, and Microsoft offer passkey sync through their cloud services. If you set up a passkey on your phone using Google's system, you might be able to use that same passkey when logging in on your computer. This requires that both devices are connected to the same account (like your Google account or Apple ID). The passkeys are encrypted before being sent to the cloud, meaning the company storing them can't see your actual passkey information. This gives you the convenience of accessing your passkey from multiple devices while maintaining security.

Another option is platform passkeys, which work specifically on devices made by the same company. An Apple passkey created on an iPhone works on other Apple devices like a Mac or iPad. A Windows passkey works on Windows devices. This approach keeps your passkeys within one ecosystem.

Security keys represent a different type of passkey solution. These are physical devices (similar to a USB drive) that store your passkey. You plug the security key into your device when you need to log in. Security keys are extremely secure because they can't be accessed remotely, but they require you to carry the physical device.

Practical Takeaway: Choose between local device passkeys (most secure but only on one device), synced passkeys (works across your devices but requires cloud storage), or security keys (physical devices for maximum security). Your choice depends on how many devices you use and how much convenience you want.

Backing Up and Managing Your Passkeys

Managing your passkeys properly helps make sure you don't lock yourself out of your accounts. Unlike passwords, you can't simply reset a forgotten passkey by answering security questions. Passkeys are tied directly to your device, so if something happens to your device and you don't have a backup, recovering access may be difficult.

If you're using synced passkeys through a service like Google or Apple, your passkeys are automatically backed up to your cloud account. This means if you lose your phone or get a new one, you can restore your passkeys as long as you can sign into your cloud account. This is one major advantage of synced passkeys.

If you're using local device passkeys, you have less automatic protection. However, many services allow you to create multiple passkeys for the same account. For example, you might create one passkey on your phone and another on your laptop. This way, if something happens to your phone, you can still log in from your laptop. Some services also allow you to keep your password as a backup login method while using passkeys as your primary way to sign in. This gives you a fallback option if you lose access to your device.

It's wise to review your passkeys periodically, just like you'd review passwords. Most services show you a list of all your passkeys in your account settings. You can see when each passkey was created and sometimes which device it's stored on. If you notice a passkey you don't recognize, you should remove it. If you replace an old device with a new one, you can delete the passkey from the old device.

If you lose access to a device that holds your only passkey, you'll need to contact the service's support team. Have your account information and recovery options ready. Services typically can verify your identity through other means and may allow you to create a new passkey, but the process can take time. This is why having backup passkeys or keeping an alternative login method available is valuable.

Practical Takeaway: If your passkeys sync through the cloud, they're automatically backed up. If not, create passkeys on multiple devices or keep your password as a backup. Regularly review your passkeys in account settings to make sure they're all devices you recognize.
