A passkey is a digital credential that is used as an authentication method for a website or application). It is a type of passwordless authentication that is promoted by the World Wide Web Consortium and the FIDO Alliance). Passkeys are designed to be more convenient and phishing-resistant than conventional authentication methods). They are normally secured using possession (of the device or security key), and often utilize biometrics as an additional security factor, neither of which require the user to memorize a password). Google announced that Android and Google Chrome would support passkeys in October 2022 and support for personal Google Accounts in May 2023). Passkeys are cryptographic key pairs that are specific to a website, and one half is shared with the website, while the other half is private and stored on the users device or in their password manager. Passkeys are connected to the app or website they were created for, so users can never be tricked into using their passkey to sign in to a fraudulent app or website. Passkeys are a simpler and more secure alternative to passwords, and they let users sign in with just their fingerprint, face scan, or screen lock.
