On Linux, most modern user-facing applications are using polkit instead of sudo. You can actually just use pkexec instead of sudo in the terminal as well. Instead of just running arbitrary commands as root, applications can use specific pre-defined actions like "org.freedesktop.udisks2.filesystem-mount". This shows a nice localized message to the end user about what the app is trying to do, so they can decide whether to allow it or not. The system administrator can also configure certain actions to not even require authentication, useful for e.g. flatpak updates, or to block certain actions altogether.
