Password for Period Close?

Closing the period is asking for a password.  Why?  What is the password?

There is no password for simply closing the period\year.

However, when closing if you selected to delete history, then the password for that (purging) is DESTRUCT.  

IMPORTANT NOTE: Be sure before selecting the option to delete history that you have a good backup of the Horizon folder and that you really want to remove those records from Horizon Billing.  We actually recommend that you use the Purge History function if you want to purge data and NOT purge it as a part of the close period.
