When an account successfully logs in to the JFW platform, end-devs should collect the device information and register the device with the account.
Logging in from a device with that account is called "registering" once, and that account is considered adding one device. Many applications call it. link, attach, add, all mean the same thing.
Maximum number of allowed device
Each account has a Package that defines how many devices can gain access to the account at a time.
Before registering a new device to an account or granting access to an account, JFW will check the account device quota. When the number of devices logged into the same account exceeds the specified limit, the system will revoke access for the device with the oldest logged date. This is done to ensure that the account is not being used on too many devices simultaneously, which could compromise security and privacy or break the account device quota.
For example, an account subscribes to a Package that allows five logged devices at a time. The account owner uses a new device to access the system. If the device that has not previously been logged into the system is used to log in and the number of devices logged into the same account exceeds the specified limit, End-dev can inform the owner about the auto-revoke access behavior like this:
Information
The number of logged devices in your account exceeds the limit. Please click to CONTINUE to revoke the access for the one of other devices and grant access to this device.
Instead of auto-revoking access for the oldest logged devices, End-dev can override the default behavior like this:
In case the number of logged devices doesn’t exceed the specified limit, end-dev just lets the app work normally. Then end-dev can make a UI component to manage logged devices like this:
Since 2025, we have not used "registering" or "registered" to add the device to the user. We use the word "add" or "added". Please see glossary.jframework.io
