Hi Abhishek, There is no out of the box audience to target logged in and not logged in users. You will need to use profile attributes that captures the login information and store it in the user's profile and then build an audience of that. Eg. use some attribute such user.loggedin and set value to true or false. Then you can build a audience based on the visitor profile value.
For more information on this use case please refer to section "In-page profile attributes (also called "in-mbox profile attributes) "
under Methods to get Data into Target .
