Hi,

It should be no problem with adding other users on Odoo deployed on your "localhost", but you must allow to access your machine on the port you run Odoo Server (usually 8069). Create account for them, set their password, check your IP address in network (in wifi options - it should start with 192.168.x.x). They must be connected to the same network. 

But they cant sign in.

So - do they see login window? Please be more specific.

Hi,

When you run Odoo on your local machine using localhost, only your computer can access it because “localhost” always refers to the device you are on. So if you add team members as users in Odoo, they won’t be able to log in from their computers unless they use your machine’s local network IP address (like http://192.168.x.x:8069) instead of localhost. You also need to make sure each user has a valid login and password, is marked as active, and has a company assigned. If you haven’t configured email, you must manually set passwords for them. Additionally, your firewall must allow access to Odoo’s port (usually 8069), and in some cases, you may need to configure Odoo to listen on all network interfaces (xmlrpc_interface = 0.0.0.0) so others on your LAN can connect. Without these steps, team members will see login errors even though they exist as users in Odoo.

Hope it helps.
