Device Unauthorized

Hello forum again! Today I have gotten to the point where I am trying to link my Galaxy S5 to the Android Studio. I have downloaded the USB file and ran the .exe file that installed drivers. When I restart everything and go to Devices in Android Studio, it says the following.

device unauthorized. Please check the confirmation dialog on your device.

Im not sure what it is asking me to do except that I know it is saying that it is Unauthorized. I have also enabled USB debugging on my device. Any help would be great! Thanks!

Try this:

Disconnect the phone from the computer. Go to Settings | System | Developer Options on the phone. Turn Off Developer Options. In the Developer Options menu, select "Revoke USB debugging authorization". Plug phone into computer. Turn On Developer Options. Select "Enable USB Debugging". A notification will pop up on the phone. Select "Always allow from this computer". Select "OK" on the notification.

You should be good to go after that.
