Oracle Database Discussions

Hi,

I am running 10g2.

After following the article http://orafaq.com/node/567 to enable password on listener I was eble to set the password.
Now aftre I saved the config I was wondering why I am still able to start and stop listener without providing the password?

Here my listener.ora

# listener.ora Network Configuration File: C:\oracle\oracle\product\10.2.0\db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = C:\oracle\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
)
)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = 537CAFEBE6E)(PORT = 1521))
)
)
