Setting Up RustDesk for Remote Access
Purpose
This article shows you how to install and configure RustDesk, an open-source remote access tool. It’s used to remotely control or access client or internal computers for support or management purposes.
When to Use
Use this guide when setting up a new device for remote support via RustDesk — either for internal use (Ultrex techs) or when helping a client establish a connection for remote service.
Overview: What Is RustDesk?
RustDesk is a secure, open-source remote desktop solution that allows remote access and control of another computer. It’s a great alternative to TeamViewer or AnyDesk, providing:
- Easy remote access for IT support.
- Secure connections with optional 2FA.
- Full desktop control from anywhere.
We’ll cover setup on both ends:
- Destination computer – the system being controlled.
- Source computer – the system used to connect remotely.
Step 1: Install RustDesk on the Destination Computer
- Go to rustdesk.com and click Download.
- You’ll be redirected to RustDesk’s GitHub releases page. Under the Windows column, download the file marked .MSI.
- Once downloaded, open the file and proceed with installation:
- Click Next through the prompts.
- Accept the license agreement.
- Click Finish when done.
- RustDesk will launch automatically. You’ll see your computer’s unique ID on the left-hand side — record this ID, as it will be needed to connect.
Step 2: Configure Security Settings
Set a Permanent Password
- Click the three dots next to your computer’s ID and select Settings.
- Go to the Security tab.
- Click Unlock to enable editing.
- Scroll to Password Options → select Use Permanent Password.
- Create a strong, unique password (you can use passgen.co to generate one).
- Enter it in both fields and click OK.
Enable Two-Factor Authentication (Optional)
- Still in the Security tab, check Enable 2FA.
- Scan the displayed QR code with an authenticator app (Google Authenticator or Microsoft Authenticator are both fine).
- Enter the six-digit code from the app to finalize setup.
Tip: If you’re not already using an authenticator app, Google Authenticator is quick and easy to set up.
Step 3: Install RustDesk on the Source Computer
Repeat the same installation process on the computer you’ll be connecting from.
Once installed:
- Open RustDesk.
- In the Control Remote Desktop field, enter the destination computer’s unique ID.
- Click Connect.
- Enter the permanent password set earlier. Optionally check Remember password for future use.
- If 2FA is enabled, enter your six-digit authentication code to complete the connection.
Tips for Reliable Remote Access
- Keep the destination PC awake and online. RustDesk requires it to stay powered on and connected to the internet.
- Trust devices selectively. Only check “Trust this device” on private computers — never on public or shared systems.
- Be aware of visibility. Actions performed while connected are visible on the destination’s monitor if it’s on.
Troubleshooting
If RustDesk fails to connect or shows a timeout:
- Ensure both devices are online.
- Verify the ID and password are correct.
- Restart the RustDesk service or the app on both devices.
If issues persist, Ultrex IT retainer clients can contact support for remote troubleshooting assistance.
Recap / Key Takeaways
RustDesk provides a free, secure, and simple way to connect remotely to computers — ideal for both internal management and client support. With optional 2FA and permanent password setup, it balances ease of use with strong security.
Use this setup as a standard procedure when enabling remote access for clients or internal systems.
