Report an Issue with Verifying Your Account
perhaps you connected to facebook from another device and then forgot to disconnect since that connection is stille alive perhaps this is why you get this message.
It depends really. If you're using Opera Mini(which uses proxies) to use FB, chances are that dialog may appear. Also you might wanna visit this page on your FB https://www.facebook.com/settings?tab=security.
These settings can help in fixing your problem.
If you use some mobile browsers like UCbrowser or some other app to use facebook which redirect data through their servers located in far of places or other countries, it may show the same. Do you remember using any other application to access facebook?
