Passkey is a method of logging into an account without a password. This feature has become popular since last year because it is more secure than entering a password. Passkey uses a face scan, fingerprint or even a physical security key. Recently, Passkey has been supported on all Microsoft applications and services.
Microsoft account users can use Passkey regardless of Windows, iOS or even Android devices. With Windows devices, Passkey is either face-based or fingerprint-based Windows Hello. iOS is with Face ID and Android devices with fingerprint scanning as well.
For those who don't know, Microsoft was one of the first to take passwordless account logins seriously. 2015, Windows Hello was introduced and 2018 it started receiving FIDO recognition. Now Passkey can be used to log in Copilot, Microsoft 365, Skype, etc. accounts easily. Passkey is also used by Apple, Nintendo, Google and many others.
