 # What are managed devices / Login users / concurrent connections in `Pro`?
 
 ## Managed devices
-All devices connected to the server are counted, we can not know the device will be accessed once or many time. These devices are displayed on the `Devices` page of the `web console`. **Excessive devices will be disabled** (you can not remote access a disabled device), you can not access these excessive devices remotely. The number of managed devices on the plan is also the maximum number of items allowed in one address book.
