What is Windows Hello?
Windows Hello is a biometrics-based technology that enables Windows 10 users to authenticate secure access to their devices, apps, online services and networks with just a fingerprint, iris scan or facial recognition. The sign-in mechanism is essentially an alternative to passwords and is widely considered to be a more user-friendly, secure and reliable method to access critical devices, services, and data than traditional logins using passwords. inwindows can help you understand more about it.
“Windows Hello solves a few problems: security and inconvenience,” said Patrick Moorhead, president, and principal analyst at Moor Insights & Strategy. “Traditional passwords are unsafe as they are hard to remember, and therefore people either choose easy-to-guess passwords or write down their passwords.”
It is not uncommon for people to use the same password (or variations) across multiple sites and applications. Windows Hello and other biometric authentication features like Apple’s Face ID or Touch ID are designed to offer an alternative to passwords that is unique and more secure because it relies on technology that’s harder to break.
How does Windows Hello work?
Windows Hello limits the attack surface for Windows 10 by eliminating the need for passwords and other methods under which identities are more likely to be stolen. “Windows Hello lets a user authenticate a Microsoft account or a non-Microsoft service that supports Fast Identity Online (FIDO) by having the user set up a gesture” such as a facial scan, iris scan or fingerprint to log into a device, said Anoosh Saboori, senior program manager lead at Microsoft.
“Windows Hello uses 3D structured light to create a model of someone’s face and then uses anti-spoofing techniques to limit the success of people creating a fake head or mask to spoof the system,” Moorhead said.
Windows 10 users can set up Windows Hello in the sign-in options under account settings. Users need to establish a facial scan, iris scan or fingerprint to get started, but they can always improve those scans, and add or remove additional fingerprints. Once set up, a glance at their device or scan of a finger will unlock access to Microsoft accounts, core applications and third-party applications that use the API.
“By adopting [the] FIDO specification, partners will be delivering differentiated and innovative Windows Hello companion devices that meet the needs of both consumers and businesses, including those in heavily regulated industries,” said Saboori.
The FIDO specification was developed in 2014 by the FIDO Alliance, which now includes more than 250 companies, but was founded by PayPal, Lenovo, Nok Nok Labs, Validity Sensors, Infineon and Agnitio. FIDO authentication technology is available in hundreds of devices today, according to the group.
Support for FIDO2 security keys
Microsoft has also given support to the latest version of the security protocol, FIDO2. This lets users access standards-based devices such as USB security keys that offer an extra layer of protection when signing in to Microsoft accounts.
Shortly after the introduction of the protocol this spring, Microsoft said it was testing the use of supported devices – such as those from Yubico, HID and Feitian – in limited preview to enable users to sign in to Windows 10 devices using two-factor authentication.
And on Nov. 20, Microsoft announced that users can sign in to its online services via the Edge browser using FIDO2 devices.
Users that have installed the Windows 10 October Update that finally rolled out earlier this month can set up Microsoft’s browser to allow access to applications that require Microsoft Account authentication – including Outlook, Office and OneDrive – with a FIDO2 security key.
Who uses Windows Hello?
Windows Hello is designed for both enterprises and consumers and is gaining traction on both fronts. During Microsoft’s Ignite 2017 conference, the company announced more than 37 million people were already using Windows Hello and more than 200 companies had deployed Windows Hello for Business. At the time, the largest enterprise deployment outside of Microsoft’s IT team comprised more than 25,000 users, according to the company.
“Biometric fingerprint scanning is prevalent in the enterprise, but the issue is that it’s not readily used,” Moorhead said. Every major vendor has systems using Windows Hello, according to Moorhead, but market penetration is much lower than needed to start the process of replacing passwords for all Windows 10 users.
Though Windows Hello has a sizeable user base, it is dwarfed by the massive Windows 10 install base. If Microsoft can convert the majority of Windows 10 users to Windows Hello, it would be a watershed moment in the battle against clunky passwords.
Why would you want Windows Hello?
Passwords, in short, are a drag. In this age of password abundance (and human forgetfulness), security-minded users realize that a fingerprint, facial recognition or an iris scan to gain access to devices, important accounts and data is likely to be a safer option. Even so, the password “remains the most frequently used sign-in mechanism, but also a source of frustration for end-users,” said Raul Castañon-Martinez, senior analyst at 451 Research.
Moving from traditional passwords to stronger forms of authentication is “one of the great challenges that we face in online computing,” said Saboori. “[Microsoft] is embracing a future without passwords by building Windows Hello into the platform experience and enabling multi-factor authentication in first- and third-party applications.”
Microsoft is working with a growing number of service providers to give its users a more seamless method to authenticate multiple accounts of importance with Windows Hello. There’s a small group of Windows Hello-compatible apps on the market today, but Microsoft says more are coming. Among the apps that can use Windows Hello now are Dropbox, Enpass, OneDrive, One Messenger and OneLocker Password Manager.
What are the hardware requirements?
Windows Hello has a relatively low barrier to entry, but it does come with specific hardware requirements. Microsoft’s Surface Pro, Surface Book, and most Windows 10 PCs equipped with fingerprint scanners or cameras that can capture two-dimensional infrared spectroscopy are compatible with Windows Hello. Compatible devices from other manufacturers include HP’s Spectre X360 13, ASUS Transformer Mini T102HA and Dell XPS 13 9360.
Microsoft is also working with device manufacturers to maintain consistent performance and security for all Windows Hello users, and set high-level benchmarks and reference designs to establish baseline requirements. The acceptable performance range for fingerprint sensors is a false accept rate of less than 0.002 percent, and the acceptable range for facial recognition sensors is a false accept rate of less than 0.001 percent, according to Microsoft. That translates into 1 in 100,000 for fingerprints and half that rate for facial recognition. (For comparison purposes, Apple says the chances of fooling its Face ID is 1 in 1 million, while the chances of fooling its Touch ID are 1 in 50,000.)
Moreover, false reject rates for fingerprint and facial recognition scanners without anti-spoofing or liveness detection must fall under 5%. False reject rates for fingerprint and facial recognition scanners with anti-spoofing technology must fall under 10%, according to Microsoft’s guidelines.
For those not familiar with the technology, liveness detection does pretty much what it sounds like: it determines that a user is a living being before unlocking a device or app. All sensors must include anti-spoofing measures like liveness detection, but the configuration of these anti-spoofing features is optional and varies with different systems.
In addition to the built-in option, third-party devices allow Windows Hello to be added to other Windows 10 hardware.

Windows 10 users were given another biometric authentication method earlier this year: palm vein scanning.
Fujitsu’s PalmSecure system maps the veins in a person’s hand, using infrared rays to create a unique vein pattern image. This lets users authenticate on Windows Hello by hovering their hand over sensors embedded in some of Fujitsu’s Windows 10 laptops and tablets, or use a standalone USB sensor.
Palm vein scans are seen as more accurate and secure than other biometric methods such as iris, face, fingerprint or voice recognition. (Fujitsu has sold vein-scanning technology – first commercialized by Hitachi in 2005 – for around a decade, and includes banks, universities and healthcare providers among its customers.)
How does Windows Hello stack up against Face ID?
Windows Hello doesn’t have direct competitors because of its exclusivity to Windows 10 devices, but it does face indirect competition from the likes of Apple, Samsung and others who provide similar technology for their devices and related ecosystems. Apple’s Face ID is now in use on the iPhone X, iPhone XS and XS Max and the newest iPad Pro tablets. (On the tablets, it even works in landscape mode.)
“Windows Hello has been around since 2015, but as usual it was not until Apple came out with a similar feature that this technology got more attention,” said Castañon-Martinez. The delayed recognition could actually benefit Microsoft because Apple is drawing more attention to Face ID and helping users become more familiar or comfortable with the technology, according to Castañon-Martinez.
“The initial reaction to Face ID seems to be skepticism and a lack of trust from users,” Castañon-Martinez said. That’s not uncommon for new technology. More people are likely to embrace facial recognition biometrics as more devices with the technology are introduced and sold, he said.
According to Moorhead, Apple’s Face ID and fingerprint scanners are the most obvious competitors to Windows Hello. “Face ID works with glasses, Windows Hello doesn’t…. Windows Hello works well in the dark. Face ID, not so much,” he said. “Neither Windows Hello or Face ID work well in very bright light, but fingerprint scanners work in the bright light and the dark.”
What’s next for Windows Hello in the enterprise?
Despite Windows Hello’s slow start and a delayed uptick in usage, Castañon-Martinez is convinced it will become a standard feature available across devices.
“As consumers and enterprise upgrade their devices and software, it’ll be a matter of whether they choose to use it or not,” he said. “IT can prepare by getting familiar with the technology and its security standards. It is more likely that, once users become comfortable with it, they will prefer this type of sign-in mechanism.”
Moorhead said the onus is on businesses to push for greater adoption.
Conclusion
”Businesses need to stop complaining about security and start doing something about it. The technology is there, they just need to start adopting it,” he said. “Multi-factor biometric authentication is readily available and tested, so I think the time is now to implement it not just for device access, but for apps as well.”
