I changed my Apple ID password and keep getting a pop up from iCloud to enter my PW. Once I enter it, I get a message to type my password followed by the verification code I received on another device. (2-step authentication.)

I get the code, but where do I type my PW & code? Below is the screen and there is nowhere to type anything!

Please advise. Aresa
