Help I can no longer log in to Google

I tried to log in like I have for years via my PC, but Google just says "the device is unknown to us"
No matter what I do, I can no longer access my Google account. Neither does my girlfriend.
The password is correct, it's also correct, but Google just gives me the message "The device is unknown to us." We've been trying to log in somehow for over an hour and last night for two hours, but it doesn't work anymore. violent what...
I feel kind of bullied by Google. And now Google is really annoying me.
