Hi tpnguyen91, welcome to the forums,

What do you mean by "logged in to another computer" ??
Don't accounts login from a computer?

Are you asking ... "How can I check if an account is logged in, and if so, stop someone else logging in to the same account from another computer?"

If that is what you are asking, use a database to record the logged in status, and when processing the login check the logged in status to see if that account is already logged in.

Note: You'd need to put in some garbage collection routine to logout accounts that have been idle for a defined period of time.
