But, at present, Microsoft hasn't implemented any kind of passkey sync or backup. Passkeys are available on computers running Windows 10 and Windows 11 in Edge, Chrome, Firefox, and Brave through Windows Hello. Crucially, passkeys are synced using iCloud Keychain, so if you create a passkey on your iPhone, you can log in using it on your Mac and vice versa-at least as long as you use Safari. They're supported on iPhones and iPads running iOS 16 or later and Macs running macOS Ventura or later. Apple passkeysĪpple currently has the most complete passkey implementation. Microsoft has actually offered a limited version of passkeys in Edge for years but will be bringing them more natively to Windows later this year. There are solutions and workarounds coming, but for now, they're not as cross-platform as passwords or password managers.Īpple has recently added passkey support to iOS and macOS devices, and Google has added passkey support to Android devices (and it's coming to ChromeOS). Because passkeys are created on a specific device, they can't be shared as easily as passwords. Right now, passkey support is still a bit messy. And to be honest, we're only just about there now. Unfortunately, because there are so many companies involved and passwords are so deeply ingrained in the online world, it's taken a while for the FIDO Alliance to get passkeys to get to the point where you can actually use them. So far, that's really just a few big names like Google, Microsoft, Shopify Pay, PayPal, Adobe, and TikTok, but wider support should be coming soon. Passkeys only work with accounts that support them. For now, there are a few caveats along the way. Of course, right now this is a slightly idealized workflow-it's how things will work once passkey support is widespread. All the public and private key stuff will happen automatically in the background. When you log in to an account that uses WebAuthn, your device or web browser will prompt you to unlock your account using your pin or a biometric option like FaceID or TouchID. That way, your device can verify your identity without any sensitive information changing hands-and so there's nothing for phishers or hackers to steal.įrom a user perspective, things will be even simpler. Because the public key and private key are mathematically related, your device will be able to solve that challenge using its stored private key without revealing it to the server. The next time you go to log in to that service, it will use the public key tied to your account to create a challenge for your device. The private key, on the other hand, gets stored securely on your device, and it has to remain a secret. It can genuinely be public knowledge without it affecting your security. It gets stored on the service's servers, but it really doesn't matter if hackers steal it or it otherwise gets leaked. One is called the public key, and the other is called the private key. When you go to create an account for a service that uses WebAuthn, instead of you (or your password manager) creating a password that matches some awkwardly arbitrary criteria, your device will create a unique pair of mathematically related keys. It's the same solution that secure messaging apps use to encrypt your conversations and online payment processors use to make sure your credit card details don't get stolen, so it is well understood and widely used. Instead of a username and password, WebAuthn uses a principle called public-key cryptography to verify your identity. Passkeys are part of a new web standard called Web Authentication or WebAuthn. Now that you've got some idea of what passkeys are, let's dive into how they work-and why they offer better security than passwords. Seriously, passwords are widely considered to be a huge global problem, so there are a lot of companies interested in a better, more secure solution. Passkeys were created by an industry group called the FIDO Alliance that includes companies like Apple, Google, Microsoft, Amazon, 1Password, Dashlane, American Express, Intel, Mastercard, Meta, PayPal, Samsung, Visa, and lots more. Logging in is actually really simple (again, more on that in a bit). If all this sounds kind of complicated, don't worry-it all happens in the background. This means you don't have to remember anything, so you can't forget them like a password, and your devices get a single-use login credential each time you sign in to an account, so your account details can't easily be stolen by a hacker or phishing attack. Passkeys rely on public-key cryptography (which I'll explain in a moment) to verify your identity rather than a username and password.
