Before you start using the Portal, you’ll need to set up your merchant admin user account. Your administrator privileges allow you to set up other merchant admin users. During your first login, you’ll also be prompted to set up multifactor authentication (MFA). You can also find and manage API keys associated with your account.
For a full description of accessing administrator permissions, enabling multifactor authentication (MFA), and finding your account’s API keys, see Set Up an Admin User Account.
