“Passkeys are a new type of login credential that allow you to log in to sites and services without having to enter a password. There’s nothing to remember and you can use them with the devices you already own like your smartphone or laptop. Passkeys are built on the WebAuthentication or WebAuthn standard which uses public-key cryptography to better secure your accounts.
If you’re looking for other sites and services that support passkeys, 1Password has put together a passkeys directory that users can contribute to. It’s also searchable which makes it easy to find out whether or not a company offers passkey support.”
