Locking and Unlocking Secrets
  
  To prevent individuals and other applications from viewing 
    or manipulating your secrets, CASA enables you to lock secrets, which temporarily 
    disables the functionality of CASA.

      secrets are dimmed when CASA is locked. 
 
    - To unlock and restore functionality to CASA:
 
    - Click File > Unlock Secrets.
 
    - Enter your master password.
