my daughter lets me use her network site -using her password on my house computer.if by chance we were on it at the same time(because she has it on her mobile) would either of us know that the other one was on it at that time tia.

By network site do you mean Facebook? I believe an error will come up if more than one person logs into the same facebook account.
