How do you connect to your home computer while traveling?
The practical way to reach your home computer's screen from a phone or laptop while you are on holiday or a work trip.
Short answer
Before you leave, install Chrome Remote Desktop, RustDesk or TeamViewer on your home computer, turn on remote access and set a PIN. Leave the machine powered on with sleep disabled. On the road, sign in with the same account, pick the computer from your device list, enter the PIN and its screen appears.
What you need
Step by step
Decide what you actually need
Remote desktop and VPN are not the same thing. Remote desktop hands you the screen and mouse of the computer at home. A VPN puts you inside your home network, so you can reach files on a NAS or a printer, but you cannot drive the computer itself. If you need the screen and its installed programs, choose remote desktop.
Pick and install an app
The three easiest options are Chrome Remote Desktop, RustDesk and TeamViewer. Chrome Remote Desktop is the gentlest start because it pairs with your Google account and needs almost no setup. All three are free for personal use, and RustDesk is open source so you can even run your own relay server.
Turn on remote access on the home computer
For Chrome Remote Desktop, open remotedesktop.google.com/access in Chrome, click the download icon under "Remote Access" and install the extension. Give the computer a name, then set a PIN of at least 6 digits. Do not pick something guessable; that PIN is the only layer standing between a stranger and your desktop.
Fix the sleep and power settings
You cannot connect to a sleeping computer. On Windows, go to Settings > System > Power & battery > Screen and sleep and set sleep to "Never". On macOS, the same setting lives under System Settings > Lock Screen and Energy Saver. If it is a laptop, keep it plugged in so closing the lid does not put it to sleep.
Test the connection before you leave
While still at home, turn off Wi-Fi on your phone and connect over mobile data instead. That proves the session really works from outside your home network rather than only on the local LAN. Install the mobile version of the app too, and confirm you remember the PIN correctly.
Connect from the road
Sign in on the remote device with the same account, tap your computer's name in the "Remote Devices" list and enter the PIN. Once the screen loads, file transfer, clipboard sharing and full-screen options sit in the side menu. When you finish, end the session properly instead of just closing the window.
Add a VPN if you need network access too
If you also need a NAS, security camera or home server, install Tailscale or WireGuard on your router or a small always-on mini PC. Both work without a static IP even behind carrier-grade NAT, so they save you the hassle of port forwarding.
Harden the account before you go
Turn on two-step verification for the account tied to your remote desktop app and review which devices are currently authorized. Remove old machines you no longer use so a forgotten pairing cannot be used against you later.
Tips
Watch out
Remote desktop exposes your computer to the internet. A weak PIN or an account without two-step verification means handing a stranger every file and saved password on that machine. Also avoid connecting on public Wi-Fi without locking your device, and close the session every single time.
Frequently asked questions
+Can I connect if the computer is turned off?
No. Remote desktop apps need the computer running. If it is off, you can only wake it remotely with a Wake-on-LAN setup on your router, which takes extra configuration.
+Do I need a static IP address?
No. Chrome Remote Desktop, RustDesk and TeamViewer route through relay servers, so no static IP is required. A static IP only matters if you build your own VPN server the classic way.
+Can someone at home see what I am doing?
Yes, if the home monitor is on, your session shows there too. Chrome Remote Desktop displays a notice during the connection; for privacy, switch the monitor off or use the setting that locks the local screen.
+Does connecting from abroad cause problems?
Usually not, but signing into Google or bank accounts from the remote computer may trigger extra verification because of the location change. Bring your backup verification methods with you.
+How much mobile data does a session use?
With constant on-screen motion it can reach a few hundred megabytes per hour. Text and file work uses far less, and lowering the image quality cuts data use significantly.
