Passkeys are a way to replace traditional passwords when logging into websites or services. Instead of typing in a password, you can use your device’s authentication methods, such as Face ID on an iPhone, fingerprint sensor on an Android phone, or Windows Hello on a PC. Passkeys are built on WebAuthn technology and involve generating two different keys: one stored by the website or service, and a private key stored on your device.
If your device is broken or lost, there are backup options available. Many services that support passkeys will allow you to reauthenticate using your phone number, email address, or a hardware security key.
Passkeys are already supported by Apple’s and Google’s password vaults, as well as password managers like 1Password and Dashlane. 1Password has also created an online directory listing services that allow sign-in using a passkey.
