Explanation
The GREATEST risk pertaining to sensitive data leakage when users set mobile devices to "always on" mode is that authorization tokens could be exploited. Authorization tokens are pieces of data that are used to authenticate users and grant them access to certain resources or services. Authorization tokens are often stored on mobile devices to enable seamless and convenient access without requiring users to enter their credentials repeatedly. However, if users set their mobile devices to "always on" mode, they increase the risk of losing their devices or having them stolen by attackers. Attackers can then access the authorization tokens stored on the devices and use them to impersonate the users or access their sensitive data.
