Square Terminal Device Code: Auto-Logout & Reuse and Create Guidelines

DeesideOC — Sun, 21 Sep 2025 09:53:52 GMT

I have created a device code for our square terminal and logged in the terminal using it. It shows as paired in the dashboard. My questions are:

will the device automatically log out after a certain time period?
(it used to log out after 90 days when we used username and password to login on the device)
if it does log out automatically will we be able to login again using the same device code or will we need to generate a new one or reset the device code?

Hey there @DeesideOC. If you are using device codes on all POS devices, then automatic logout should not be a thing, anymore. However, if a device does get logged out for any reason, the device code will still work. But it will ONLY work on the device which activated it originally — not another terminal.
