A passkey is a digital credential that is used as an authentication method for a website or application). It is a new way of logging in to online accounts, services, and apps thats designed to be faster, easier to use, and more secure than passwords. Passkeys rely on public-key cryptography to verify your identity rather than a username and password. This means you dont have to remember anything, so you cant forget them like a password, and your devices get a single-use login credential each time you sign in to an account, so your account details cant easily be stolen by a hacker or phishing attack. Passkeys 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). Passkeys are intended to be used through operating system infrastructure that allows passkey managers to create, backup, and make passkeys available to the applications running on that operating system. Passkeys are a significantly more secure alternative to passwords, and under ideal circumstances, they authenticate that you are in possession of your device, and that you are the one accessing your account.
