Is there a way to prevent concurrent logins to the Erwin Web Portal tool? (4292965)

Problem:  Is there a way to prevent concurrent logins to the Erwin Web Portal tool. For security purposes, we do not want to allow concurrent logins so that we can limit the possibility of an attacker logging in with the same credentials elsewhere.

Solution:  As long as you have a license that includes any number of concurrent users, then our product (just like many other application servers) will not restrict concurrent logins with the same username.
However, our product allows customers to define their own login rules using OAuth:
