Passkey (credential)
Passkey, also known as security key, is a pair of cryptographic keys that is generated by a user's authenticator bounded to an account to authenticate a user's identity against a remote application or system by using public-key cryptography, thus avoiding the need to reveal the secret key hold by the user through public channels. The current popular implementation of passkeys for general public usage in web technologies is proposed by FIDO Alliance and standardised by the World Wide Web Consortium under the WebAuthn standard, and passkeys is generally referred as a de-facto non-technical term of WebAuthn credential.
