Mac address with hotspot users

RouterOS Beginner Basics
1

I have routerOS v4.11. Is it possible to specify more than one MAC address for one user.

For example, a user can only login from two Mac address instead of one Mac or any Mac.

No, that is not possible.
At least not with local users, or User Manager.

OK, it it possible to have two users but they can not login in the same time.
