Connect Nano 33 IoT to WiFi

Hello
I am making a project for stables to cool stables with sprinklers. I made the first concepts with Arduino mega, but now I also want to control it with the phone.

I chose an Arduino iot 33 from this, but I can't connect it to the router. When I do a WiFi check, it says the WiFi routers, but it says encryption. I have routers without wifi password is this necessary to connect??
Can someone help me
Thank you in advance for your thoughts
