Which term describes installing an app on a mobile device from outside the official app store?

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

Answer: (D)

Sideloading is installing an app on a mobile device from outside the official app store. It means sourcing an installation package from non-store channels and manually installing it, such as an APK on Android or an enterprise-signed app. This bypasses the store’s vetting and signing processes, which can increase the risk of malware or tampering if the source isn’t trusted. The other terms describe different ideas: phishing is about tricking someone into revealing information, rooting is gaining elevated control on the device, and unlocking refers to removing restrictions to run software or access deeper system features. Sideloading specifically targets the method of obtaining and installing apps outside the official store.
