Under 'Preferences' click on 'Account' tab where you will see 'Sign out' button. Once you click on this button, it Signs out from all the Creative Cloud applications.
The other simple solution is: Once you launch any Adobe Creative Cloud application like Photoshop or Indesign, choose "Help" > Signout. Even this step will deactivates all the other CC applications.
Later, when you launch any application, it would say that it is running in trial version and will prompt you to enter your credentials.
