Chrome Remote Desktop is an app everyone should add to Chrome. You can find it here. There's no question remote access and support applications have come a long way in the past few years. But the best ones, like GoToAssist, weren't cheap. Chrome Remote Desktop (CRD) is an excellent alternative. If you're a GoToAssist power user, you'll want to take your time to review the features of CRD to see if it works for you. But for most people it'll make an excellent addition to their app toolkit.
Here is Google's description:
Chrome Remote Desktop allows users to remotely access another computer through Chrome browser or a Chromebook. Computers can be made available on an short-term basis for scenarios such as ad hoc remote support, or on a more long-term basis for remote access to your applications and files. All connections are fully secured.
Chrome Remote Desktop is fully cross-platform. Provide remote assistance to Windows, Mac and Linux users, or access your Windows (XP and above) and Mac (OS X 10.6 and above) desktops at any time, all from the Chrome browser on virtually any device, including Chromebooks.
Once you visit the Chrome Web Store and search for Chrome Remote Desktop, you'll select CRD to 'Add to Chrome', you can find it by opening a new Chrome tab and checking in Apps.
When you open the app, it will walk you through several approvals - these just allow CRD to work on your computer. Anytime you're sharing your computer with another person, you'll know because you'll have to generate a one time code for that sharing session only; this is common to other remote support applications like GoToAssist. After you're done setting up the app, you'll see the options below anytime you launch the app.
So if you help mom or dad with tech support, CRD is a blessing. If you need to access remote machines for administration or other tasks (I often need to access Windows desktops and servers from my Mac for example), CRD can be an excellent option. From my experience, Chrome is often already present in support situations and setup for Remote Support or Remote Access is as simple as it gets.
If Chrome isn't available on a machine you're supporting remotely, the process of downloading and installing Chrome and adding the Chrome Remote Dektop app is typically about the same as the process of installing GoToAssist. Once Chrome and Chrome Remote Desktop are present, connecting is much easier than leveraging GoToAssist or similar.
It's amazing what you can do with a browser these days!
