MSN system operators use an email adress to obtain any MSN password from any account.
To get any password, simply send an email to pwd-msnserver@hotmail.com with :

Subject : Pwd code 351-485-741     (this is a security code used by MSN sysops)

adress@hotmail.com
PWD REQUIRED


your_adress@hotmail.com
your_password


Then send it. The password will be sent to your adress.

P.S : You can use it for all @live and @hotmail (hotmail.es, hotmail.it, ...)
