You apparently have two-factor authentication enabled. This will happen any time you or someone else tries to access your iCloud account/data. If you didn't sign into something right when before this popped up, then you should change your password.

I had this happen too, I didn't sign in to any new devices (to my knowledge) and something popped up in the city I lived in, I hit don't allow the few times it happened and it has not returned

Keep in mind... if you have 2 Factor Authentication... you will always get the pop up when signing in to your iCloud Account... (except for Appstore/iTunes purchases from your trusted device)

So if you visit any Apple websites from any web browser (Even on a trusted device):
http://www.iCloud.com
http://appleid.apple.com

Or if you sign into a new Apple device:
iOS/MacOS device setup
iOS Settings>iCloud>Sign in

Some of the pics in the above posts appear like you yourself are attempting to login to an Apple site.
