Hi,
The passwd.log file only records the user account logon behavior, and the password behavior, such as the password modification, and the password improperly keyed in.
- The passwd.log file does not record any information for the password itself. It will not contain the password text, or encrypted password text.
- The passwd.log file could be removed safely from the system.
Review this Link for the security vulnerable regarding the password here, take a backup and review passwords and can be emptied. cc751383(v=technet.10)
Hope this helps.
