Steam Remote Play: 2 Best Ways to Enjoy It Anywhere

If you want to experience your Steam library remotely anytime, anywhere, here are two main options:

1. Use Steam Remote Play

Steam’s official Remote Play feature is the most direct option. It’s free and integrates perfectly with the Steam platform. As long as both devices are on the same network, you can connect quickly with a few simple steps.

However, it has a key limitation — it’s highly dependent on your network environment. When connecting across different networks, you may encounter lag and reduced visual quality.

2. Use DeskIn — A Professional Remote Gaming Solution

As a professional remote desktop software, DeskIn delivers a smoother, more reliable gaming experience than Steam’s built-in streaming.

It provides stable cross-network connectivity through over 200 global relay nodes, ensuring fast and secure links. Powered by ZeroSync® and RTC real-time communication, DeskIn maintains fluid visuals and input even across long distances — no need to be on the same Wi-Fi.

In addition, DeskIn offers advanced image optimization to maintain sharp visuals under low bandwidth (up to 4K 60FPS or 2K 144FPS). Most importantly, DeskIn isn’t limited to Steam — it supports all PC games and applications, giving you maximum flexibility and freedom.

1. Using Steam Remote Play

Steam Remote Play is an official feature within the Steam ecosystem, giving it excellent compatibility and integration. For players with large Steam libraries, it’s the simplest and most direct way to play remotely — completely free of charge.

It syncs your Steam account, game progress, and achievements seamlessly, and supports Windows, macOS, Linux, and mobile devices. With just a few steps, you can start streaming your PC games remotely.

Requirements Before You Start

1. Both devices must be connected to the same network, ideally with a stable Wi-Fi speed of 5 Mbps or higher.

2. Both devices must have Steam installed and logged into the same account, and the host PC must be powered on and running Steam.

3. Make sure firewall and router settings allow Steam connections for smooth communication between devices.

How to Use Steam Link for Remote Play

Step 1: Install Steam and Log In

Make sure both your host (gaming) PC and client device have Steam installed and are logged into the same account. Keep the host computer powered on and running Steam.

Step 2: Enable “Remote Play” on Your Host Computer

Open Steam, click “Steam” → “Settings” → “Remote Play”, and check “Enable Remote Play.” Click OK to save your settings.

Step 3: Pair Your Devices
Install the Steam Link app on your client device (phone, tablet, or another computer) and connect to the same Wi-Fi network. When prompted, enter the security code shown on your client device into the host PC to complete pairing.

Then, select a game from your library — Steam will automatically connect, and you can start playing as if you were on your main computer.

Despite its convenience, Steam Remote Play has some clear drawbacks:

• Network-dependent: Unstable Wi-Fi (e.g. 2.4GHz) can cause blurry visuals, lag, and delayed input.

• Connection instability: Long sessions may lead to disconnections, audio sync issues, or stuttering.

• Same-network restriction: Steam Link only works within the same local network — remote access from outside isn’t supported.

• Limited mobile experience: Few customization options, poor button mapping, and less flexible controls on mobile.

2. Using DeskIn for Remote Steam Gaming — Simple & Smooth

If you’ve faced any of the above issues with Steam, DeskIn is the better solution. Designed for high-performance remote gaming, DeskIn offers smoother visuals, more stable connections, and lower latency than Steam Remote Play.

An account keeps your connections secure, makes managing multiple devices easier, and ensures smoother performance.

Step 2: Connect Your Phone and Computer

Open DeskIn on both devices. On your phone, enter the connection password (you can customize it for convenience, e.g., “1234567c”).
If both devices are logged into the same account, you can connect instantly without entering a password.

Tap “Connect” — and within seconds, you’re ready to play.

Step 3: Start Playing Remotely

Once connected, you can control your PC directly from your phone’s touchscreen and play any game in your Steam or Epic library — anytime, anywhere.
Whether it’s MapleStory, Lineage, GTA V, or Monster Hunter, you’ll experience the same smooth, full gameplay as if you were on your desktop.

Method 2: Use Parsec

Parsec is another excellent remote desktop solution for gamers. It uses advanced hardware-accelerated encoding, delivering near-native gaming performance with latency as low as a few milliseconds.

Compared with standard remote software, Parsec is optimized for gaming — supporting 60FPS high-frame-rate streaming and easy setup. From AAA titles to indie favorites, Parsec lets you enjoy full PC gaming freedom on your devices.

However, the mobile version currently supports only Android, not iOS. Android users can connect via phone or a compatible controller for low-latency play, but Parsec doesn’t offer mobile-side custom controls — making it slightly less flexible than DeskIn.

The following steps focus on using Parsec for PC-to-PC gaming.

Step 1: Install Parsec

Download and install Parsec on both computers, create an account, and sign in on both devices.

Step 2: Set Up Host and Client Computers

• Open Parsec and log in.

• On your main (gaming) computer, click the blue “Share” button to generate a connection link.

• Copy and send the link to your other computer.

• On the client PC, paste the link into the box at the bottom right and click “Join.”

Step 3: Start Playing

Once connected, your desktop will appear, and you can start playing immediately — just like gaming locally.

Method 3: Cloud Gaming Services — Play Without a High-End PC

If you don’t own a powerful gaming computer or want to reduce hardware costs, cloud gaming is a great alternative.
Services like GeForce NOW, Xbox Cloud Gaming, or Steam Cloud Play let you stream games from cloud servers directly to your phone, tablet, or laptop — with no need for high-end hardware.

Benefits

• Easy Setup: Install the official app or log in via browser to start playing instantly.

• Play Anywhere: Enjoy PC or console games at home, while commuting, or at a friend’s place.

• Cost-Effective: No need for expensive GPUs or PCs — enjoy AAA games affordably.

• Auto Updates & Cloud Saves: Games run and save progress in the cloud automatically.

Drawbacks

• Limited game libraries — not all titles are available.

• Most services require monthly subscriptions.

• High-speed internet is a must to maintain quality.

• Limited MOD/customization support.

• Some platforms are not yet available in Asia.

If you prefer full control over your own PC while keeping flexibility for both work and play, DeskIn offers a more versatile, subscription-free solution.

Step 1: Sign Up and Log In

Choose your preferred cloud gaming service, create an account, and install its app — or log in directly through your browser.

Step 2: Choose a Game and Start Streaming

Select your game and click “Play.” The game will stream directly to your device.

Step 3: Customize Controls

Most cloud platforms support on-screen buttons or external controllers for complete control on mobile or tablet.

Whether you want to continue your Steam progress on the go or enjoy a AAA title on your laptop at a café, DeskIn lets you play freely — without distance or hardware limits.

In recent years, data breaches have become increasingly alarming. Just last year alone, over 1 billion records were stolen by hackers — a truly staggering number. What’s even more concerning is that remote control attacks on computers are now more frequent than ever.

According to a study by Check Point Research, between August 2024 and January 2025, the top three targets for cyberattacks in Taiwan were hardware suppliers, government and military agencies, and the manufacturing industry. Whether you’re an individual user or a business, it’s time to take computer security seriously.

If your computer has been acting strangely — for example, your mouse moves on its own, files are mysteriously modified, or the system suddenly slows down — that could be a sign of a hacker intrusion. Sometimes, a remote desktop program you used before may still be secretly running in the background. Once your system is under malicious remote control, not only can your personal data be stolen, but your computer might also be used as a tool to attack others.

This article provides a full guide on how to detect, block, and prevent such threats — helping you regain control of your computer.

How to Detect If Your Computer Is Being Remotely Controlled

If you suspect that your computer is being accessed remotely, the first step is to learn how to detect it. Fortunately, you can use built-in system tools and commands to quickly check if someone is secretly accessing your device.

Detect Remote Control on Windows

Windows provides several built-in tools for system inspection. The following three methods can help you identify unusual remote connections quickly.

Method 1: Check Logged-In Users via Command Prompt

1. Press Win + R to open the Run dialog box, type cmd, and hit Enter.

2. In the Command Prompt window, enter the following commands:

Code block

1 quser

2 query user

3. Review the results — if you see unfamiliar accounts currently logged in, it may indicate that your computer is being remotely accessed.

Method 2: Check Active Users via Task Manager
This is a straightforward and real-time way to view all logged-in users.

1. Press Ctrl + Shift + Esc to open Task Manager.

2. Go to the Users tab.

3. Review the list — under normal circumstances, you should only see your current account.

Method 3: Track Login History via Event Viewer
Event Viewer provides detailed system activity logs, making it perfect for tracing login behavior.

1. Search for and open Event Viewer from the Start menu.

2. Go to Windows Logs > Security.

3. Look for Event ID 4624 (Successful Logon) and check for suspicious remote login entries.

Detect Remote Control on macOS

While macOS uses a different approach, the underlying logic is the same — spotting signs of unauthorized access.

Method 1: Check Screen Sharing Settings

1. Go to System Preferences > Sharing.

2. Verify that Screen Sharing and Remote Login are turned off.

3. If these services are enabled without your knowledge, your system might be compromised — disable them immediately.

Method 2: Monitor Network Connections
Use the built-in Activity Monitor to observe network usage and identify any unusual activity.

How to Block Remote Control on Your Computer

Once you’ve confirmed that your computer is being remotely controlled, it’s time for emergency action. Whether you use Windows or Mac, these methods can help you cut off the connection and stop further control.

Stop Remote Access on Windows

Windows’ built-in Remote Desktop and Remote Assistance features are often exploited by hackers. Disabling them is the first step toward stronger protection.

Method 1: Disable Remote Desktop and Remote Assistance
This is the most direct way to block unauthorized access.

1. Press Win + R, type control, and hit Enter.

2. Go to System and Security > System > Remote settings.

3. In the Remote tab, uncheck Allow Remote Assistance connections to this computer.

4. Select Don’t allow remote connections to this computer and click OK.

Method 2: Adjust Windows Firewall Settings
Even after disabling remote features, you can add extra protection via the firewall.

1. Open Windows Defender Firewall.

2. Click Allow an app or feature through Windows Defender Firewall.

3. Click Change settings, then uncheck Remote Assistance and Remote Desktop.

4. Save your changes.

Method 3: Disable Unnecessary Remote Services
Use Services Manager to completely disable remote-related background services.

1. Press Win + R, type services.msc, and hit Enter.

2. Locate and disable the following services:

• Remote Desktop Services

• Remote Registry

• Telnet (if enabled)

3. Set their startup type to Disabled.

Stop Remote Access on Mac

macOS manages remote access centrally through System Preferences.

Method 1: Disable Remote Access Features

1. Go to System Preferences > Sharing.

2. Uncheck the following:

• Screen Sharing

• Remote Login

• Remote Management

• Remote Apple Events

3. Ensure all remote access options are turned off.

Method 2: Check and Remove Unknown Apps
Some remote control apps may be installed without your consent.

1. Go to the Applications folder.

2. Look for unfamiliar remote control software — such as TeamViewer, AnyDesk, or Chrome Remote Desktop.

3. If you didn’t install them yourself, remove them immediately.

How to Prevent Future Remote Control Attacks

Emergency actions alone aren’t enough — long-term protection is key. Building a multi-layered security strategy will greatly reduce your risk of remote access attacks.

Strengthen Authentication

• Use complex and unique passwords with uppercase, lowercase, numbers, and symbols.

• Enable two-factor authentication (2FA).

• Change passwords regularly and avoid using the same one across multiple services.

Manage Updates and Patches

In 2024, hackers exploited 768 vulnerabilities with CVE numbers — a 20% increase from 2023. Keeping your system updated is crucial.

• Enable automatic system updates.

• Regularly install security patches.

• Keep your antivirus definitions up to date.

Strengthen Network Security

• Use a VPN to encrypt your connection, especially on public Wi-Fi.

• Avoid unsafe public networks.

• Change your router’s default password and review settings regularly.

• Install reputable antivirus software with real-time protection.

• Run full system scans regularly.

• Use secure remote desktop software with encrypted connections.

Among many options, DeskIn stands out for its solid security foundation.
