Is Windows Hello an example of passwordless authentication?

Windows Hello is indeed an example of passwordless authentication. It provides a more secure and convenient way for users to access their devices and services without relying on traditional passwords. Instead of a password, Windows Hello uses biometric recognition methods such as facial recognition or fingerprint scanning, as well as PINs, which can be tied to the device itself rather than the user's online identity. This minimizes the risks associated with password theft and enhances user experience by allowing for quicker access.

The design of Windows Hello emphasizes security by leveraging trusted platform modules (TPM) and hardware-based security features that protect user credentials. Therefore, it not only serves as a mechanism for authentication but also enhances overall security by reducing vulnerabilities associated with lost or compromised passwords.
