This article explains how to audit/capture what user passwords are altered in the database.
A user with the "ALTER USER" privilege can alter other users passwords. Oracle provides Client events through which these operations can be traced. You can use "AFTER ALTER" or "BEFORE ALTER" Client Event to capture the details pertaining to the altered user.
The trigger will fire only for the normal users. It will not fire when the monitored action is executed by a SYSDBA user or by a user being granted the ADMINISTER DATABASE TRIGGER privilege
The following example will collect:
1) The user that executed the "ALTER USER" statement
2) The name of the user whose password was altered.
