HR ACCESS stores the user passwords without encryption in the UC10 table. As an Oracle DBA, if you have access to the database instance, all you have to do is issue the following command through SQL*PLUS:
SQL> select cdutil, cdpass from UC10;
CDUTIL CDPASS-------- --------
USER1 PASWORD1
USER2 PASWORD2
USER3 PASWORD3
USER4 PASWORD4
USER5 PASWORD5
Happy computing.
