The official Decky store (accessible through the loader) curates plugins, providing a degree of quality control and reducing the risk of encountering harmful software.
• Root Access and System Modification: It’s important to understand that installing Decky Loader involves running a script that modifies your system, specifically by installing a system service and files that require root privileges. While the installation script itself is well-vetted, any plugin you install through Decky Loader also runs with elevated privileges or interacts with system components. This means that if a malicious plugin were ever to bypass the community checks, it could potentially cause harm.
• Best Practices for Digital Security:
  • Source from Official Channels: Always install Decky Loader using the official method provided by the developers (typically a one-liner script from GitHub).
  • Install Reputable Plugins: Stick to plugins available through the official Decky store. Avoid side-loading plugins from unverified sources.
  • Research Before Installing: If you’re unsure about a plugin, a quick search online for reviews or discussions can often reveal potential issues.
  • Keep Your System Updated: Ensure your Steam Deck’s SteamOS is up to date, as Valve frequently releases security patches.
  • Understand the Risks: While generally safe and widely used, remember that you are modifying your system outside of Valve’s direct support. In rare cases, a plugin conflict could cause instability, though this is usually reversible.

In conclusion, Decky Loader is considered safe by the vast majority of its users and the broader Steam Deck community due to its open-source nature and active community oversight. However, like any software that allows system modification, users should exercise caution and adhere to best practices for digital security to minimize any potential risks.
