WiFi login question

Why is it that the wifi setup only asks for a password?
I am trying to access a wifi signal that I know for fact doesn’t require a website to accept the EULA or anything. Just a username/password.

Can I enter a username in anywhere?

right now, no

I’m just curious then…what username does it throw to the router? Does it give an anonymous username?

wifi only need password for sure
username is for router admin page, and the admin page is in that router, not in GameShell
