Multiple Device login from Single User in MCF application

Hello Experts,

We have implemented SAP Multichannel Foundation for Utilities and Public Sector (a responsive design app) in our system.

Now we have the below requirement.

"When any user is going to login into the MCF application, first we need to Verify that there is no logged for that user, if there is a logged on a different device the Office Virtual displays the following message:There is another open session, the Virtual Office will close the other session and continue with the login ."

Can anyone please help how the verification for multiple device login can be done ?

Thanks & Regards,
