com.apple.icloud helper wants to use login keychain
I just started getting this message, but haven't changed any passwords recently. Also beginning yesterday, every time I open my MacBook, it will not connect to the internet. I click the same internet I've been using from the list of available networks and it says the password in my keychain is not correct. When I click cancel, it then connects to the internet without me having to enter any information. Any idea what's going on? I'm hesitant to enter login password, etc in case I've been hacked.
MacBook (Retina, 12-inch, Early 2015), iOS 10.3.3
