FusionReactor supports an on-premise and SaaS (cloud) product interfaces. Customers may use the on-premise only or a hybrid, on-premise + SaaS UI.
If you choose on-premise only, then your product license(s) will be managed via the FusionReactor portal https://portal.fusionreactor.io/
If you have chosen the SaaS (cloud) solution, then you will receive a single license key and this is managed via the SaaS (cloud) interface here https://app.fusionreactor.io/ This UI provides access to your application monitoring information, billing and user management information.
It is possible to login to both of these accounts using the same login as they are different URL's.
