Every SellerActive account is associated with a single email address and password. Everyone accessing that account would be utilizing this same set of credentials. While we do log when updates are submitted to the marketplace, we will not log who specifically made these adjustments within a single SellerActive account.
Currently, we do have the ability to separate Order Management, and Inventory Management accounts through a custom secondary password, but there would not be different login credentials. This secondary password would need to be used every time you would wish to jump between these two features.
If you have more than one store for a specific integration, we can sync them together so you can utilize a single set of login credentials and access all stores in a single interface. You can sync quantities together between various accounts, however you will need to communicate with your implementation specialist for more details (this is not enabled "out of the box").
