This is my first question for this community,
suppose, user ABC is login with his user name and password(as he is owner), and XYZ is also login with ABC's id & Pw (as he stolen his Password). pl note that, in this condition if XYZ logged in only before ABC, then only ABC can identify the illegal usage of his ID.(with help of POP-UP message)
my question is, how can i trace out the other users who are using our ID & PW,after my login ??
Thanks in advance.
