I keep getting "incorrect verfication" code

Hi EJ_Ando,

Thank you for using the Apple Support Communities! To clarify, are you following the steps in the article below to receive a verification code:

Get a verification code and sign in with two-factor authentication

If so, is your iPhone a trusted device and updated?

Thank you.

I had this last week with an trusted device and.I did everything right. An hour later it was working again...
