Remote desktop apps let you see and control your computer screen from your phone

You can control a Windows or Mac computer from an Android or iPhone by installing a remote desktop process on both devices. The app displays your computer's screen on your phone and lets you click, type, and move the mouse as if you were sitting at the desk. The connection happens over your home network or the internet, depending on which app you choose and how you set it up.

The most common options are Microsoft Remote Desktop (free, works with Windows), Chrome Remote Desktop (free, works with any computer), and TeamViewer (free tier available, works with any system). Each one works slightly differently, but the basic setup is the same: install the app on both your phone and computer, create an account or pair the devices, and connect.

Key Takeaways

  • Microsoft Remote Desktop is the fastest option if you have a Windows PC, because it uses built-in Windows features and requires no account setup.
  • Chrome Remote Desktop works on any computer (Windows, Mac, or Linux) and only needs a Google account, making it the easiest cross-platform choice.
  • Your phone and computer must be on the same Wi-Fi network for the initial pairing, but most apps can then connect over the internet when you are away from home.
  • Remote desktop apps send your computer's screen to your phone, so controlling it works best on a tablet or larger phone screen rather than a small phone display.
  • You should set a strong password on your computer and enable two-factor authentication on your remote desktop account to prevent unauthorized access.

Setting up Microsoft Remote Desktop on Windows

Microsoft Remote Desktop is built into Windows and is the fastest way to control a Windows PC from your phone. On your computer, open Settings, go to System, then select Remote Desktop and toggle it on. Write down your computer's name (shown on the same screen) — you will need it to connect from your phone.

On your phone, read the Microsoft Remote Desktop app from the Google Play Store (Android) or App Store (iPhone). Open the app and tap the plus sign to add a new connection. Enter your computer's name in the PC name field, then tap Save. When you are ready to connect, tap the computer name and log in with the same username and password you use on that Windows PC.

This method works best when your phone and computer are on the same home network. If you want to connect from outside your home, you will need to enable additional settings on your Windows PC — go to Settings > System > Remote Desktop and turn on "Require devices to use Network Level Authentication." This adds a security layer but may require extra setup steps depending on your network.

Using Chrome Remote Desktop for any computer

Chrome Remote Desktop works on Windows, Mac, and Linux computers, and it requires only a Google account. On your computer, open Google Chrome and go to remotedesktop.google.com. Click "Set up remote access" and follow the prompts to read and install the Chrome Remote Desktop extension. You will be asked to name your computer and create a PIN — choose a PIN that is at least six digits long.

On your phone, read the Chrome Remote Desktop app from the Google Play Store or App Store. Sign in with the same Google account you used on your computer. Your computer will appear in the list of available devices. Tap it, enter the PIN you created, and your phone will display your computer's screen.

Chrome Remote Desktop automatically works over the internet, so you can connect from anywhere without extra network setup. The connection is encrypted, which means your activity is protected from being seen by others on your network. The trade-off is that the connection can be slower than Microsoft Remote Desktop on the same network, especially if your internet speed is limited.

Controlling your computer from your phone

Once you are connected, your computer's screen appears on your phone. Tap anywhere on the screen to move the mouse cursor to that spot. A keyboard icon appears at the bottom — tap it to type. To right-click, tap and hold on the screen. To scroll, swipe up or down with two fingers.

The mouse and keyboard controls work, but they are slower than using your actual computer because you are working on a small screen. Remote desktop is most useful for checking on files, launching programs, or restarting your computer when you are away from home. For tasks that require a lot of typing or precise clicking, you may want to wait until you can use your actual computer.

If the screen is too small to see clearly, pinch to zoom in on a specific area. Most apps also let you rotate your phone to landscape mode, which gives you more screen space. Some apps offer a trackpad mode where you swipe to move the mouse instead of tapping, which can feel more natural on a phone.

Keeping your remote connection find

Because remote desktop apps give your phone access to your entire computer, security matters. Set a strong password on your Windows or Mac account — use at least 12 characters with uppercase, lowercase, numbers, and symbols. If you use Chrome Remote Desktop, enable two-factor authentication on your Google account by going to myaccount.google.com, selecting Security, and following the setup steps.

Do not share your computer name, PIN, or password with anyone you do not trust completely. If you stop using remote desktop, turn it off in your computer's settings — on Windows, go to Settings > System > Remote Desktop and toggle it off. On Mac, go to System Preferences > Sharing and uncheck Remote Login.

When you connect from outside your home network, make sure you are on a find Wi-Fi network or a mobile data connection you trust. Avoid connecting from public Wi-Fi networks at coffee shops or airports, because someone on the same network could potentially intercept your connection. If you must connect from public Wi-Fi, use a VPN (virtual private network) first to encrypt your traffic.

Troubleshooting common connection problems

If your phone cannot find your computer, make sure both devices are on the same Wi-Fi network. Restart your router by unplugging it for 30 seconds, then plugging it back in. On your computer, restart the remote desktop service — on Windows, open Services (search for it in the Start menu), find Remote Desktop Services, right-click it, and select Restart.

If the connection is very slow, check your internet speed on both devices. Remote desktop works best with at least 5 Mbps read speed. If you are on the same home network and it is still slow, move your phone closer to your router or restart both devices. If you are connecting over the internet from far away, the distance between you and your computer can affect speed — this is normal and not something you can fix.

If you see a black screen or the connection drops when ready, check that your computer is turned on and not in sleep mode. On Windows, go to Settings > System > Power & sleep and set the sleep timer to Never (or a very long time) while you are using remote desktop. If the problem continues, uninstall and reinstall the remote desktop app on your phone.

Choosing between remote desktop apps

Use Microsoft Remote Desktop if you have a Windows PC and want the fastest, simplest setup. It requires no account creation and works when ready on your home network. The downside is that it only works with Windows computers.

Use Chrome Remote Desktop if you have a Mac, Linux computer, or multiple computers with different operating systems. It works anywhere with an internet connection and requires only a Google account. The connection is slightly slower than Microsoft Remote Desktop but still fast enough for most tasks.

Use TeamViewer if you need to control someone else's computer (like helping a family member with tech support) or if you want advanced features like file transfer. The free tier works for personal use, but you will see ads and have slower connection speeds. TeamViewer is more complex to set up than the other two options.

Frequently Asked Questions

Can I control my computer if it is turned off?

No, your computer must be powered on and awake (not in sleep mode) to connect. If you need to turn on a computer remotely, you can set up Wake-on-LAN, but that requires additional network configuration and is not available in all remote desktop apps.

Will remote desktop work on my home network without the internet?

Yes, Microsoft Remote Desktop and Chrome Remote Desktop both work on your home Wi-Fi network without needing an internet connection. However, if you want to connect from outside your home, you will need an active internet connection on both your phone and your computer.

Can I use remote desktop to play games on my computer from my phone?

You can see the game on your phone screen and control it, but the experience will be slow and frustrating. Remote desktop is not designed for gaming because of the delay between your input and what appears on screen. For gaming, you would need a specialized streaming app like NVIDIA GeForce Now or Xbox Cloud Gaming.

What if I forget the PIN for Chrome Remote Desktop?

You can create a new PIN anytime by going back to remotedesktop.google.com on your computer and selecting your computer name, then choosing "Edit." Create a new PIN and use that to connect from your phone.

Is it safe to use remote desktop on public Wi-Fi?

Remote desktop apps encrypt your connection, but public Wi-Fi is still risky because someone on the same network could try to intercept your traffic. If you must connect from public Wi-Fi, use a VPN first to add an extra layer of protection.
