AP Stylebook Online concurrent-user licenses use two forms of security: You create a custom URL like apstylebook.com/yourcompany name and you tell us the IP address(es) your team members will use to access your account.

If you have users working remotely, make sure you provide us with the broadcast IP for your VPN so we can include it in your IP range list for access. Then your users can log in through your VPN or proxy server for easy access. 

If you have users who work remotely off your network range and do not use a VPN or proxy server, you can assign them an individual login account. For each individual account you assign, the total number of available concurrent users you have decreases by one. For example, if you have a 25-seat concurrent-user site license and assign five individual accounts with a login, up to 20 concurrent users could access the site concurrently. Adding named-user can be done by an Account Manager via the "Manage Users" (https://www.apstylebook.com/account/account_members) section of the Account Dashboard and making sure they are assigned a seat in the subscription via the "My Products" page (https://www.apstylebook.com/licenses).

Please make sure your proxy is allowing traffic from *.apstylebook.com so images, css and javascript load from these subdomains.
