Hi,
We did not implement this function in ABP.
I can give you some idea
- When the user logins you can add a random GUID value to the claims, and store the GUID in the cache(can be a list, if you want to limit to allow only three concurrent logins, then the length of the list is 3 : https://docs.abp.io/en/abp/latest/Authorization#claims-principal-factory
- Write an ASPNETCORE middleware to check the current user's claims, if the GUID value is not in the allowed list, return unauthorized
