messed up with 2FA and upgrading my phone

Hi all ! need help here, I changed my phone Friday and since, I can't work online anymore, reason is that I had enabled the 2FA on my phone (previous) and guess what ... I didn't pay attention to this, I saved to iCloud, restored on the new one and wiped everything for resell the old iPhone ... ofc my 2FA was not transferred. How can I drop it ? Same for the xxx.1password.eu website, I can login and enter my login/password and secret key and then plouf ! it ask for the 2FA code.
Thanks for any advise.
