Login Problem

[Apolemicc]

Alright, this is kinda new for me to deal with...So...

I login, or so I think, and once my password is confirmed the system brings up a message to enter an "Authenticator code", and below it says to enter the "generated digital code."

I'm trying to find where my screen shots are saved so, here's my phone having took a picture instead since I'm probably a bit dumb for it.

I don't know what to do, someone let me know.
