Yubico’s Hanson noted that from a security perspective, “Sign in with Apple” or “Sign in with Google” offers roughly the same security as passkeys stored by Apple, Google, or Microsoft. In the long run, passkeys will be easier and safer for website operators, too, as they will no longer need to store passwords, which means they won’t need to worry about password-database breaches (though they’ll still need to secure the rest of the data they collect).Ī username-and-password combo isn’t the only type of login you can use to access websites and apps, of course: Apple, Google, and other tech companies let you use your credentials for their respective services to sign in on websites across the internet. “I’m hugely hopeful about the ability for this to get us to a new era in terms of end-user security.”

“There’s no password attacks when there’s no password present,” Microsoft’s Weinert said. Passkeys aren’t perfect, but they are expected to be an improvement over the status quo. And since one side of the key is linked to the web-based service itself, it can protect against phishing attempts, because your device should recognize a phishing website as a fake. Passkeys aren’t reused across sites like passwords often are, so stolen credentials do less damage. Passkeys solve two of the biggest problems with passwords: data breaches and phishing. Why is a passkey more secure than a username and password? He added that the scrutiny that the standards provide also makes the company more confident about passkeys’ widespread adoption. “Standards equal security,” said Alex Weinert, Microsoft’s director of identity security. What’s important is that passkeys should work more or less the same across platforms and will be supported for years to come. You don’t need to remember any of that in order to use passkeys. Apple, Google, and Microsoft, along with other tech giants, are working with the FIDO Alliance on passkeys, which are based on what’s known as the WebAuthn standard. Passkeys are based on standards developed by the major tech companies.

If you’re logging in on a device other than the one you used to create the passkey-say, you’re logging in on a Windows laptop for an account whose passkey you created on your iPhone-the device where you created the passkey needs to be physically near the device you’re using to log in, something that the system checks through the scanning of a QR code and the use of Bluetooth Low Energy.Īll of this sounds complicated, but the end goal is for the experience of logging in with a passkey to be easier than doing so with a username and password, and for it to work almost like shopping using a credit card, “where the experience is more or less the same everywhere you go,” said Derek Hanson, Yubico’s vice president of solutions architecture and alliances. To grant the website access to that key, you have to authenticate with whatever means you use to unlock your device, such as a fingerprint, your face, or a PIN. When you log in to the website, it checks with your device to see if the two keys match.

On a technical level, your device uses what’s known as asymmetric cryptography (or public key cryptography) to register a public “key,” which is then stored on a website for which you have an account alongside a private key that’s stored only on your device your device creates a new private key for each site you register.

Instead, each account you have is linked to a key on a device, such as an iPhone or Android phone. It might be best to think of a passkey as a “password 2.0”-a passkey is functionally the same as the username-and-password combination you’re used to, just without, well, an actual password. The system for using a passkey in the real world is very much a work in progress, but the goal is for you to be able to log in to every account the same way you unlock your phone, with biometrics or a PIN. Their solution is called a passkey, and though this new sign-in method isn’t yet widespread, it is now rolling out-and it promises to make creating new accounts online and logging in to them securely a lot easier.

But Apple, Google, and Microsoft are working together to support a new way for people to log in to accounts without using passwords at all. Thinking of new passwords and then keeping them organized and secure is a pain, even with a password manager.
