Here are 3 free software to login to PC by plugging in a USB drive.
These software are handy to either login to PC automatically by inserting a USB or use a key along with USB to login. Although you can also login to PC using your account password, but there are few benefits of using a USB as login key. It can come in handy when you want to let someone use your PC without typing the account password in front of that person, when you don’t want others to peek on your account password when login to PC, etc. All you need to do is configure your USB drive to lock and unlock your PC using any of these software. After this, whenever you will eject your USB drive, your PC will be locked automatically, and you can use the same USB to login to PC without using your PC account password.
VSUsbLogon is a great software in this list to lock as well unlock your PC using the USB drive. Unique feature provided by this software is that you can set the delay time to lock your PC using presets. So when you have configured your USB drive to lock/unlock your PC and eject your USB drive, it will show a delay time and lock your PC when the timer is over. After this, you can use the same USB drive to unlock your PC.
Apart from this, you can also configure your USB drive to use a PIN (not your Windows account password) to unlock your PC. Moreover, all your input data remains secure using AES-256 encryption algorithm.
USB Raptor is also handy to lock/unlock your PC using the USB Drive, but it has few interesting features. For example, you can lock its interface so that no one can change the configurations. Apart from this, you can also use it to either enable System Lock or USB Raptor lock. If USB Raptor Lock is enabled, it won’t provide option to unlock PC using Windows account password.
USB Raptor also comes with an option to unlock PC only with a specific USB drive. It is done by detecting the serial number of USB. So even if you have used some other Pendrive, it won’t unlock the PC. Hence, security level is a bit high in this software in comparison to other software available in this list.
While using it for the first time, it lets you configure the USB drive in just three easy steps. After this, you can access Advanced configuration to access rest of the options.

It’s a fact that all the software in this whole list are great in what they are supposed to do. However, if I talk about security level, then USB Raptor is the perfect software for you to lock/unlock PC using USB drive and password protect its interface.
