Wifi "action needed" and "windows security" sign-in?

Hello y'all,

I'm using Windows 10 on my Asus Notebook, and I'm having difficulty connecting to a specific wifi network.

The error began appearing a couple days ago. Originally I ignored it and just connected to another available wifi, but seeing that the current one is substantially slower than the one I used to use, I wish to resolve the issue.

The wifi network I wish to connect to uses a login/password but I've connected to it many times before. However, now, when I click to connect, a message pops up, asking me to sign into "Windows Security". What account am I supposed to use to sign in?

I've tried my microsoft account, but it still didn't allow me to connect.
