Matrixcli logs in as a new device every time it is used

Hi, I am using matrixcli to log in and check my unread messages, and it mostly just works great. However every time it checks my unreads (once every 3 minutes) it logs in as a new device, meaning I now find myself with tens of thousand of devices on my account, which is a big problem because it makes managing logins practically impossible. Is there any way to solve this
