Hi Erron,

Afaik the platform doesn't log devices. What is your scenario?

As per the below thread my understanding is that you have 2 main challenges,

• Make sure that you have 1 active user login from 1 device not multiple devices.
• Make sure that no multiple users can access the same device.

To do so you will need the following,

• Database Entity to store UserID  & Device ID.
• Local Storage Entity to store Current User Id & Device Id.

In the first screen after login you will have to do the following checks,

• Get current User ID and search in the Local Storage & Server for the Devices info.
• Search by UserID in Local Storage,
  • If Exists then update it.
  • If not then create it.
• Search by UserID & Device ID on Server,
  • Delete the results. Why delete? you might do 2 search queries by UserID & DeviceID and gets 2 different rows, so which one to update & which to delete? Unless you don’t have a logic or a key to keep the row with current device or keep the row with the current row, delete both.
  • Create a new one record with new data.
• You will need to check on app resume every time if the server data is different than local then logout & if not then remains,
• 

Please let me know what do you think ?
