Simultaneous login limit per user (devices that do not use ZCC)

My company uses devices where ZCC cannot be installed. (Printers, servers, etc.)

But I don’t want to bypass the authentication, is it possible to create one dedicated user to log in all the target devices?

Can you tell me if there is a limit to the number of simultaneous logins per user?

Might be useful to clarify your question a bit, zscaler has a feature called special users that you could use for your case (example: unknown-useragent@xxx), there is no count for number of devices but there is a fee for traffic in this case. However i would like to understand why do you want to authenticate non-users in the first place…
