If you want to change the email address you use to log into CTAIMACAE, you need to contact the same person who originally registered you and requested you to upload your documentation. Each customer manages the logins and registration of users themselves and CTAIMA does not always have this information.
However, if you do not have this information, we will be happy to assist you. You can contact our customer service ([email protected]) and they will indicate how to proceed in your specific case.
