This article provides merchants and partners  information about Multi-factor Authentication, an additional security layer used to verify a user's identity when logging into the Merchant Interface or Partner Interface.

What is Multi-factor Authentication?

Multi‑factor authentication helps prevent unauthorized access to your account by requiring two forms of verification:

How to log in with Multi-factor Authentication?

1. Merchants go to Merchant Interface, Partners: go to Partner Interface.

2. Enter your Username and Password on the Log In page then click "LOG IN".

3. On the Verify Your Identity page, click on the method you want the PIN delivered.

4. Obtain the PIN from either your email or text service.

5. On the next page, enter the PIN you received then click on 'VERIFY PIN".

What should I do if I don't receive the PIN emails?

1. Look in Spam/Junk, Clutter, Promotions, or Other/Focused inboxes.

2. Check any email rules or filters that might be auto‑moving or deleting messages.

3. Wait a few minutes, then request again. MFA emails can be delayed due to high system or email provider throttling. Avoid requesting repeatedly in rapid succession.

4. Consult with your Email Provider or IT Team:

• Ask if these emails are being blocked or quarantined (some organizations silently block automated security emails)
• Ask if the Authorize.net email domain can be whitelisted

5. Try a different device.

6. Clear browser cache and/or use a different browser.

Multi-factor Authentication (MFA) Frequently Asked Questions FAQ

• Why did you start requiring MFA?

  • Multi‑factor authentication adds an extra layer of protection to your account. Even if someone were to get access to your password, they wouldn’t be able to sign in or make changes without this additional verification step.

• Can the PIN verification be disabled?

  • No, the PIN verification step can not be disabled nor is there an opt-out option.  While the extra verification step can feel inconvenient, MFA is an effective way to protect unauthorized access to your account. Our goal is to keep your information safe while minimizing disruption.

• Can the frequency of verifications or PIN requests be changed?

  • There is no option to change the frequency of verification or PIN requests.

• Can I have my browser store and autofill my Login ID and password to log into my account?

  • To decrease potential account security risks, the ability to use a browser's password manager to autofill your Login ID and password is not available.

• I added a mobile phone number to my user profile, why do I not see an option to send the PIN via text?

  • Currently the option to have the PIN sent via text is only available when logging into the Merchant Interface or Partner Interface.
