As you know, the USB security keys are a secure medium to validate a lot of components in a computer. They can be used to log in to Windows 10. Now with the advancement of APIs, you can authenticate across the website as well using the same key. However, there are times when it may not work and it could be caused by several factors. It could be due to corrupted or incompatible drivers or it could also be due to compromised integrity of the key, and many more.
So if you happen to encounter an issue with the USB security key on your Windows 10 computer, then there are several potential fixes you can try. You can try toggling the Internet Options settings or reinstall the respective USB drivers. You could also try changing the PIN of the security key or disable the antivirus program on your computer or troubleshoot the web browser. Refer to the potential fixes provided below to fix the problem.
Note that this option is only a temporary measure as it can make your computer vulnerable. Make sure to press the Reset all zones to default level button.
If updating the drivers of the device did not fix the problem with the USB security key, you can try to update or reinstall the Universal Serial Bus Controller drivers instead of using the Device Manager. Refer to the following steps:
Note: If it is a regular USB drive, then it will be listed as a USB Mass Storage Device but if you have a USB 3.0 device, then look for a USB 3.0 Extensible Host Controller.
Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.
If the first two options didn’t work, you can try changing the PIN of the security key. There are instances when the PIN for the security key might have been corrupted. Thus, resetting it can help you resolve the problem.
Firewall and antivirus programs are known to block the proper functioning of the USB security key. Thus, your antivirus or firewall programs might be the reason why you can’t download anything on your Windows 10 computer. To isolate the issue, you need to temporarily disable both the Firewall and antivirus programs and then check if you can now download anything from the internet. Do not forget to enable them again as disabling them can leave your computer vulnerable to cyber threats.
Troubleshooting your web browser can also help you fix the USB security key problem. You can do that by checking if your web browser supports the security key and you can do that by checking on the official website of your browser. You can also try to update your web browser to its latest version but if it didn’t help, you can try to reinstall it or switch to another web browser.
