When you encounter the prompt "Windows Hello isn't available on this device", you should first clarify whether the device meets the hardware requirements: 1. Face recognition requires an infrared camera; 2. Fingerprint recognition requires a dedicated reader; 3. Although PIN login does not require additional hardware, it may be subject to other conditions; if the hardware supports it but still cannot be used, you should check whether the driver is the latest, whether the system is updated to the latest version, and confirm that the device is Windows certified; in addition, you should also check whether the account type is a Microsoft account, whether the Group Policy restriction function is enabled, and whether the TPM is enabled; finally you can try restarting the device, running troubleshooting, or re-adding an account to clear cache issues.
Windows Hello is a very convenient authentication feature in Windows 10 and 11, supporting face recognition, fingerprint recognition, or PIN login. But if you encounter the prompt "Windows Hello isn't available on this device" when setting it up, it means that your device does not currently support this feature, or some conditions are not met.

The reasons for this problem are diverse. The following is analyzing it from several common perspectives and providing corresponding solutions.

1. Hardware not supported is one of the main reasons
Windows Hello is not available to all computers, it has certain hardware requirements:
- Face recognition : Infrared cameras (IR Camera) are required, and ordinary cameras cannot achieve safe face recognition.
- Fingerprint recognition : A dedicated fingerprint reader is required, and many thin and light notebooks or entry-level models are not equipped.
- PIN Login : Although no additional hardware is required, it is sometimes restricted to enable if the other two methods are not available.
? Check method :

- Open Settings > Account > Login Options;
- If there is only password option but no Windows Hello related options, it means that the current device may not have the corresponding hardware.
? Suggestions : If you really want to use Windows Hello, you can consider connecting an external compatible USB camera or fingerprint reader.
2. Driver or system problems cause abnormal functions
Sometimes Windows Hello can be unavailable even if there is appropriate hardware, but the driver is not installed correctly or the system version is too old.
? ?Troubleshooting steps :
- Update the drivers of the camera or fingerprint reader, and you can find relevant devices in the Device Manager;
- Make sure the system has been updated to the latest version, and some old systems may not support certain login methods;
- Check whether the device has passed Windows authentication in Settings > System > About.
? Tips : If you find a yellow exclamation mark in the device manager, it means there is a problem with the driver. Right-click to select "Update Driver".
3. Account type or security policy restrictions
In some cases, even supported devices may cause Windows Hello to be unavailable due to account or group policy settings.
? Possible reasons :
- Using a local account instead of a Microsoft account;
- Business or school accounts are subject to organizational strategies;
- The security module (such as TPM) is not enabled or damaged.
? Solution suggestions :
- Try to switch your local account to a Microsoft account;
- If it is a company device, contact the IT administrator to confirm whether the relevant functions have been disabled;
- Check whether TPM (Trustable Platform Module) is enabled in the BIOS/UEFI settings.
4. Temporary system errors or caching problems
Sometimes it is just a small system failure, and it can be restored by restarting or clearing the cache.
? Try the following :
- Restart the computer and then enter the settings to view;
- Use the Troubleshooting tool to check for login-related issues;
- Delete existing accounts and re-add them, sometimes fixing identification exceptions.
Basically, these common reasons and coping methods are all about. If your device itself does not support Windows Hello hardware, there is no need to force it. But if you should have supported it but cannot use it, you can follow the above ideas to check it step by step. The problem often lies in the driver, system version or account settings. It is not complicated to solve, but details are easy to ignore.
