Newly Generated Password Notification to User

Hi,

I am generating a random password as per client's password policy through workflow and setting it while creating account in Active Directory. Now I need to notify user about this new password directly with out the interference of any system team user. 

How can I achieve this via MIM?

Moreover, I know about the password reset portal provided by the MIM. Can I use the same portal or any other service provided by MIM through which user can generate his/her password first time by some verification via EMAIL or SMS or security questions?

Thanks

F.
