Beginning September 2023, Authorize.net will be further enhancing the login process requiring all users to perform further verification via a temporary one-time passcode sent to your user’s email address, which is now required to access your account.
Additional information on multi-factor authentication can be found in our support article: What is multi-factor authentication?
