multiple virtuemart sites with one UPS and Authorize account?

[Samstha]

Hello,

I am trying to setup 2 websites for my mother and my sister. I have already finished one.
The question is could I use the same UPS access code, UPS user id and UPS password for the second virtuemart site? and same with the Authorize.net gateway information? Both website will be operating under one umbrella (for example ABC Co; first website DBA ABCMom, and second website DBA ABCsister)

Any help would be appreciated!
