For example; If you change this user’s password with new password as follows,

But if you want to use the old password, you can reset it the old password using the HASH Value as follows.

 

SQL> alter user mehmet identified by values '9A479F1118EF7F0E';

User altered.

You can extract the HASH value of Oracle user password as follows.

 

SQL> select
2 extract(xmltype(dbms_metadata.get_xml('USER',username)),'//USER_T/PASSWORD/text()').getStringVal() the_old_password
3 from dba_users
4 where username = 'MEHMET';
