Installing an app to a mobile device without using an app store is known as?

• A. Jailbreaking
• B. Rooting
• C. Phishing
• D. Sideloading

Answer: (D)

Sideloading refers to installing an app from a source other than the device’s official app store. This is common on Android when you install an APK from a third‑party site, or in some cases on iOS via enterprise certificates or developer installations. The key idea is bypassing the store’s vetting process, which can introduce security risks because the app may not have been checked for malware or tampering. Jailbreaking and rooting describe removing built‑in restrictions to gain deeper control over the OS, which can enable sideloading but are broader actions than the act of installing outside the store itself. Phishing is a social engineering tactic used to steal information, not related to how apps are installed. Therefore, the term that best fits the scenario is sideloading.
