SSID without username and password

RouterOS Beginner Basics
1

Hello, guides. I have two UniFi U6 access points connected to a Dahua PoE switch via a Mikrotik RB1100 router. I've set up a bridge and VLAN's interfaces (10, 20, 30, and 40) and connected them to different UniFi networks.

My only issue is with VLAN 20, which is the guest SSID. I want any client to be able to access the guest network via a QR code without needing a username or password. The private logo will then appear, and they will be able to access the internet. I also want a specific policy to be applied to VLAN 20 (192.168.20.0/24) limiting upload and download speeds to 10 Mbps for only 10 minutes every 24 hours.
I not want to creats 1000 username
the SSID guest its open password

Your QR code can consistent the password. But where is MikroTik in this question?

I want to apply all policies only to vlan 20 via MikroTik router and not Unifi AP.

MikroTik manages all operations; only UniFi broadcasts the networks.

Aah…perhaps hotspots can supply this kind of functionality.

I tried every possible method and it all failed.
