Hi,

It’s not possible to lock an Odoo Enterprise database on Odoo.sh based on a client machine’s MAC address. Odoo.sh runs entirely in the cloud, and the MAC address of a user’s local device is never exposed through the browser or any HTTP request, so there’s no way for any website - Odoo or not - to read or validate it. Even if you tried workarounds, MAC addresses can be easily changed or spoofed, so it wouldn’t be reliable.

Hope it helps
