->**Note:** When Windows 10 first shipped, it included **Microsoft Passport** and **Windows Hello**, which worked together to provide multifactor authentication. To simplify deployment and improve supportability, Microsoft has combined these technologies into a single solution under the **Windows Hello** name. Customers who have already deployed these technologies will not experience any change in functionality. Customers who have yet to evaluate Windows Hello will find it easier to deploy due to simplified policies, documentation, and semantics.

 - **Fingerprint recognition** uses a sensor to scan the user’s fingerprint. Although fingerprint readers have been available for computers running the Windows operating system for years, the detection, anti-spoofing, and recognition algorithms in Windows 10 are more advanced than in previous Windows versions. Most existing fingerprint readers (whether external to or integrated into laptops or USB keyboards) that support the Windows Biometric Framework will work with Windows Hello.
 - **Iris scanning** uses cameras designed to scan the user’s iris, the colorful and highly detailed portion of the eye. Because the data must be accurate, iris scanning uses a combination of an IR light source and a high-quality camera. Microsoft Lumia 950 and 950 XL devices support this technology.

 > Users must create an unlock PIN while they enroll a biometric gesture. The device uses this PIN as a fallback mechanism in situations where it cannot capture the biometric gesture.
 
 All three of these biometric factors – face, finger, and iris – are unique to an individual. To capture enough data to uniquely identify an individual, a biometric scanner might initially capture images in multiple conditions or with additional details. For example, an iris scanner will capture images of both eyes or both eyes with and without eyeglasses or contact lenses.

 Many assume that original equipment manufacturers (OEMs) must implant a TPM in hardware on a motherboard as a discrete module, but TPM can also be effective when implemented in firmware. Windows 10 Mobile supports only firmware TPM that complies with the 2.0 standard. Windows does not differentiate between discrete and firmware-based solutions because both must meet the same implementation and security requirements. Therefore, any Windows 10 feature that can take advantage of TPM can be used with Windows 10 Mobile.
