At the moment it is not possible to change the data while signing up. If you are in a hurry and want to get your Penta account ASAP, please start the onboarding process all over again with a different email address. You can change this email address later.
If you want to edit the data in your existing application or if you wish to use the same email address, please contact our customer support. Please keep in mind that it will take us some time to update the information for you.
