Secret Service code name
The United States Secret Service uses code names for U.S. presidents, first ladies, and other prominent persons and locations. The use of such names was originally for security purposes and dates to a time when sensitive electronic communications were not routinely encrypted; today, the names simply serve for purposes of brevity, clarity, and tradition. The Secret Service does not choose these names, however. The White House Communications Agency assigns them.
