How to control your PC remotely using your smartphone or tablet (Android, iOS)
So, install Google Chrome if you haven't already and head over to the Chrome Web Store to download the Chrome Remote Desktop app. Once it's been added to Chrome, open it and log in with your Google account, granting the required permissions.
Next, you will have to enable remote connections on your PC. This can be done by clicking on “Get started” in the “My Computers” section of the setup screen and installing the Chrome Remote Desktop host.
Finally, after remote connections have been enabled, you will be prompted to set up a PIN of at least six digits. Make sure to remember it, as you will have to enter it on your mobile device in order to authorize the connection. This is a one time requirement, although you can choose to be asked to enter the PIN code every time.
Once you're done with that, grab your phone or tablet, head over to the Play Store or the Apple App Store and download the Chrome Remote Desktop app. The process is identical on both Android and iOS. Just open the app, log in with the same Google account that you you're using on your PC, enter the same PIN code, and you should see a list of the names of all your computers. Chrome Remote Desktop can be used to control multiple PCs with a single mobile device and all you need to do is repeat the process for each one.
Congratulations, the touchschreen of your mobile device is now both a touch pad and a “window” to your PC. You can pinch to zoom, use a virtual keyboard, open and close programs on your computer, switch it off remotely, tap the screen with two fingers for a right click and even send a Ctrl + Alt + Del command by tapping the three dots in the top right corner of the screen.
