Forcing login details on installing apps

[kepler20b]

Is there a way for you to always force entering user/login details when installing any applications on yosemite? even if it is from a trusted site or place?

Where are you installing them from? And how are you installing?

Downloaded from MAS? Or a .dmg online?
If from online:
Is it running an installer/pkg? Or are you simply dragging the .app to the Applications folder?
