Do you love to login to your Windows user account with a smile? Do you have a netbook, notebook or PC with a webcam? If so, here is a free and excellent software that lets you log in by face recognition instead of entering your password.

KeyLemon is an excellent software to ease and secure the login process in Windows. By installing KeyLemon, you can automatically log in to your user account without touching the keyboard and mouse. In case your webcam or KeyLemon stops working, you can manually login by typing your username and password.

Another exciting feature of this software is that it supports multiple user accounts as well. If you have two or more user accounts, KeyLemon automatically recognizes your face and logs you into the right account.

How to set up and use KeyLemon:

Step 1: Connect your webcam to the PC, install necessary drivers provided by the webcam manufacturer, and make sure that the camera is working. If you own a notebook or netbook with a built-in camera, just download the required drivers and install them.

Step 2: Visit this page, download the KeyLemon installer, and then run the setup file to install KeyLemon on your PC.

Step 3: On the first run, KeyLemon Wizard will appear. The wizard will help you select your webcam and create a face model to login to Windows. You can also manually launch the wizard by opening the KeyLemon Control Center and then clicking on the Wizard button.

Step 4: In the wizard, select your webcam, and position yourself in front of the camera to fit the drawn shape. Click the Next button to continue.

Step 5: Here, again, you need to take the correct position in front of the camera. When the camera and KeyLemon detect your face, it will show a green button, indicating that KeyLemon has successfully recognized your face. Click on the Adapt your face model button to create your face model. Wait until the progress bar reaches the 100 percent mark.

Once done, click the Next button.

Step 6: This is the last step of the wizard. Here, you need to enter a name for your face model, and also you need to enter your Windows user account password for adding the newly created face model to Windows.

Finally, click the Finish button to close the wizard. You are done! You have successfully set up KeyLemon. From now onwards, you will see a KeyLemon thumbnail on the login screen. Upon recognizing your face, KeyLemon will automatically login to your account. An option will also be available to login using your Windows user account password in case you need it.

Please note that the free version of KeyLemon includes only basic features. The basic version of KeyLemon is free and works well. Gold and Bronze versions of KeyLemon are also available with additional features and security.
