It is possible to connect to the database without specifying a password   Once you ve done that you can then reset the passwords   I m assuming that you ve installed the database on your machine  if not you ll first need to connect to the machine the database is running on    Ensure your user account is a member of the dba group   How you do this depends on what OS you are running  Enter sqlplus    as sysdba in a Command Prompt shell Terminal window as appropriate   This should log you in to the database as SYS  Once you re logged in  you can then enter  alter user SYS identified by  newpassword     to reset the SYS password  and similarly for SYSTEM     Note  I haven t tried any of this on Oracle 12c  I m assuming they haven t changed things since Oracle 11g
