Wireless Network Auth Problem

I have Mikrotik and eth3 is connected to the hub then Wireless Router connected to the said hub.
I make a hotspot user (for admin and user) with that eth3.

Problem :

  1. My device connected to Wireless Router > Need Log in > Success
  2. Then, another device connected to Wireless Router > Auto login with the same user from no.1

Why another device doesn’t need to log in?
