Passkey

A passkey is a cryptographic key, typically a string of characters, used to authenticate a user or device to a service. It serves as a secure replacement for traditional passwords by utilizing public-key cryptography and biometric authentication, enabling login without the need to remember or manage complex passwords. Unlike passwords, passkeys are tied to a specific device and service, making them more resistant to phishing and account takeover attacks. They provide a simplified and more secure login experience by leveraging the security features of the user's device, such as fingerprint recognition or facial recognition. This method enhances security by eliminating the need for shared secrets vulnerable to breaches.
