The Credit Limit Override Password window allows you to set the password that is used in the Credit Limit Override window to continue with a sale that you were prevented from recording because the customer had exceeded the credit limit.
Important:
When you're alerted to enter a password when entering or recording a sale, you don't have to click in the Override Password field first; simply start to enter the password.
This window can only be reached, and is only needed, if you mark the If Credit Limit is Exceeded on Sale preference in the Preferences window - Sales view and choose Prevent Unless Overridden as the kind of notification you want to receive.
