Client can’t get QR code for 2 factor authentication

I set up Coinbase in my clients website in Woo Commerce. Everything seemed to have gone well. When I was finished I went into the settings and changed the email addresses to his email address (instead of mine). He cannot even get into his dashboard unless he has the code generated from the authenticator app from when I set it up. Nowhere did it say to keep this code. I saved the Seed phrase and recovery codes but not the original code I used to set up the account. He needs access to the QR code so they can have access to generate the 2 factor authorization code.
