If you offer group memberships to corporate, education, or other teams of customers, this code recipe, which works in conjunction with the Limit Logins Add On, allows you to limit active sessions for a single user account.

How it Works
The code recipe filters pmpro_limit_logins_number_simultaneous_logins
to allow a defined number of active “sessions”. It requires the Limit Logins Add On to be installed and activated.
The Code Recipe
Adding the Recipe to Your Website
You can add this recipe to your site by creating a custom plugin or using the Code Snippets plugin available for free in the WordPress repository. Read this companion article for step-by-step directions on either method.
Customize the number of simultaneous logins you would like to allow before the limit is reached. The current recipe allows three simultaneous logins, which means that three individual people can be logged in to the same user account from different locations at one time.
If a fourth person tries to log in, the oldest login session for that user account is automatically logged out.
