Want to know whether your device supports biometric authentication? Use the checker above to find out whether your browser can access a user-verifying platform authenticator, such as fingerprint authentication, Face ID, Touch ID, or Windows Hello.
The check runs directly in your browser. It does not ask you to scan your face or fingerprint, and it does not collect or upload your biometric information.
What Is Biometric Authentication?
Biometric authentication is a security method that uses a physical or behavioral characteristic to verify your identity.
Common examples include:
- Fingerprint recognition
- Face recognition
- Touch ID
- Face ID
- Windows Hello
- Other device-based biometric authentication systems
Instead of typing a password, you can use a supported biometric method to unlock your device or authenticate to a website or application.
Modern browsers can use the Web Authentication API (WebAuthn) to work with platform authenticators built into a device. These authenticators are also used by technologies such as passkeys.
How Does This Biometric Authentication Check Work?
This tool uses a browser feature called:
PublicKeyCredential.isUserVerifyingPlatformAuthenticatorAvailable()
The browser checks whether a user-verifying platform authenticator is available on your device and returns a simple yes-or-no result.
The check happens locally in your browser.
It does not:
- Scan your fingerprint
- Take a picture of your face
- Read your fingerprint data
- Store your biometric information
- Upload biometric information to our server
- Require you to log in
If the browser reports that a platform authenticator is available, your device and browser have access to a supported user-verification mechanism.
What Can This Tool Detect?
Depending on your device and operating system, the available authenticator may be associated with technologies such as:
Fingerprint Authentication
Many phones, tablets, and laptops include fingerprint sensors. Examples include Android fingerprint authentication and laptops with built-in fingerprint readers.
Face Authentication
Some devices use facial recognition for user verification. Apple's Face ID and compatible Windows Hello facial recognition systems are examples.
Touch ID
Apple devices with Touch ID can provide a platform authenticator through the browser.
Windows Hello
Windows Hello can provide user verification through fingerprint, facial recognition, or other supported Windows authentication methods.
Device PIN or Passcode
A platform authenticator does not always mean that a fingerprint or face sensor is available. Depending on the device and authenticator configuration, user verification can involve a PIN, passcode, or another device-level authentication method.
This is an important distinction: the browser's WebAuthn API generally tells the website that a user-verifying platform authenticator is available; it does not provide a detailed hardware report identifying the exact biometric sensor.
Does This Tool Scan My Fingerprint or Face?
No.
This tool does not request a fingerprint or facial scan.
The browser API used by the checker only reports whether a suitable platform authenticator is available. The website does not receive your fingerprint image, facial image, or biometric template.
Your biometric data remains managed by your device's operating system and authentication hardware.
Is My Biometric Data Sent to This Website?
No.
The check is performed through your browser's WebAuthn capabilities. The result is essentially an availability check rather than a transfer of biometric information.
No fingerprint image or facial image is sent to WhiteScreenHD.
What Does "Biometric Authentication Available" Mean?
If the checker reports that biometric authentication is available, it means your browser can access a platform authenticator capable of user verification.
For example, this could be:
- A fingerprint reader on a laptop
- Windows Hello on a Windows PC
- Touch ID on a Mac
- Face ID on an iPhone or iPad
- Fingerprint or face-based device authentication on Android
However, the result should not be interpreted as a guarantee that a particular biometric sensor exists.
The browser intentionally provides websites with a limited capability signal rather than exposing detailed biometric hardware information.
Why Does My Device Have Fingerprint or Face Unlock but the Tool Says Unavailable?
There are several possible reasons.
1. Your browser may not expose the capability
The browser and operating system must support the relevant WebAuthn functionality.
2. The authenticator may not be configured
Your device might contain biometric hardware, but fingerprint or face authentication may not have been configured.
3. You may be using an unsupported environment
Browser support can vary depending on the operating system, browser version, embedded browser, or security configuration.
4. The page must use HTTPS
The Web Authentication API is a secure-context API, so browser authentication features generally require HTTPS.
5. Browser privacy or security restrictions
Certain browser configurations, permissions policies, or restricted browsing environments can prevent WebAuthn functionality from being exposed.
Why Does My Desktop Computer Say No Biometric Authentication?
A desktop computer may not have a built-in fingerprint reader or compatible facial-recognition hardware.
For example, a desktop PC with a standard webcam does not automatically mean that it supports Windows Hello facial authentication.
Similarly, a regular USB camera cannot necessarily be used as a biometric authenticator.
If your computer has compatible hardware but the tool reports unavailable, check whether Windows Hello or another supported authentication method has been configured in your operating system.
What Is a Platform Authenticator?
A platform authenticator is an authenticator integrated into the device rather than a separate security key.
Examples can include:
- Fingerprint sensors
- Face authentication hardware
- Touch ID
- Windows Hello
- Device-based passkey authentication
WebAuthn uses platform authenticators to provide secure authentication without requiring a traditional password.
What Is the Difference Between Biometrics and Passkeys?
Biometrics and passkeys are related, but they are not the same thing.
A passkey is a cryptographic credential used to authenticate to a website or application.
Biometric authentication can be used by the device to authorize access to that credential.
For example, when you sign in to a website using a passkey, your device might ask you to:
- Touch the fingerprint sensor.
- Look at the camera for face authentication.
- Use Windows Hello.
- Enter your device PIN.
The website does not necessarily receive your biometric information. The device performs the local user verification and uses the credential to complete the authentication process.
Which Devices Can Support Biometric Authentication?
Modern devices can support platform authentication across several operating systems.
| Device | Possible Authentication |
|---|---|
| iPhone | Face ID or Touch ID |
| iPad | Face ID or Touch ID |
| Mac | Touch ID |
| Windows PC | Windows Hello |
| Android phone | Fingerprint or face authentication |
| Android tablet | Fingerprint or face authentication |
| Chromebook | Device-dependent authentication |
| Linux PC | Depends on hardware and browser support |
Actual availability depends on the device hardware, operating system configuration, browser, and authenticator setup.
Browser Support
The WebAuthn platform-authenticator availability API is supported by modern versions of major browsers, including Chrome, Edge, Firefox, and Safari. Support can vary on older browsers and specialized browser environments.
For the most reliable result, use an up-to-date version of your browser and make sure your device authentication method is configured.
Is This the Same as Testing My Fingerprint Sensor?
Not exactly.
This tool does not perform a hardware diagnostic of your fingerprint sensor.
Instead, it checks whether the browser can access a user-verifying platform authenticator.
For example, if your phone has a fingerprint sensor but the browser does not expose the required WebAuthn capability, the tool may report that an authenticator is unavailable.
Likewise, an "available" result does not necessarily tell us whether the device is using fingerprint, face recognition, or another verification method.
How to Check Your Result
After running the check above, you may see information such as:
Platform authenticator: Available
This means the browser reports that a user-verifying platform authenticator is available.
You may also see an estimated authentication method. Treat this as an indication rather than a hardware-level diagnosis because the browser does not expose the exact biometric hardware to the website.
Frequently Asked Questions
Can a website access my fingerprint?
No. Websites do not receive your raw fingerprint through this API. WebAuthn is designed so authentication can occur without exposing the user's biometric data to the website.
Can a website see my Face ID data?
No. A website cannot use this check to retrieve your Face ID or facial biometric data.
Does this tool save my biometric information?
No. The tool does not collect or store fingerprint or facial biometric information.
Does my phone need a fingerprint sensor?
No. A supported platform authenticator can use different forms of user verification. Depending on the device, this may include fingerprint, face authentication, or a device PIN.
Why does the result change between browsers?
Different browsers and operating systems can expose WebAuthn capabilities differently. Make sure you are using a current browser and that your device authentication is configured.
Can I use biometric authentication to log into websites?
Yes. Many websites now support passkeys and WebAuthn. A compatible device can use a platform authenticator to verify you during authentication.
Does this tool require my fingerprint?
No. The checker does not initiate a fingerprint or face scan. It only checks whether a suitable user-verifying platform authenticator is available.
Privacy
Your privacy matters.
The biometric authentication check is designed to run locally in your browser. It does not need access to your fingerprint image, face image, or biometric template.
The tool only uses browser-provided authentication capability information to determine whether a user-verifying platform authenticator is available.
For the technical details, the underlying WebAuthn API is standardized by the W3C and implemented by modern browsers.
