Email is considered less secure than other MFA factors, so use this option as a last resort. To use MFA though a secondary email:

• All of your customers need to have activated the Allow suppliers to use Email MFA permission. This change may take up to 24 hours to take effect.
• If you have several customers and one of them has not activated the option, you need to use MFA through another method.

To enable MFA via email, follow the next steps:

1. Go to the Account Settings page. You can reach this page by selecting your profile name on the top-right corner of the window, and selecting the Account Settings option.
2. Select the Security & Multi Factor Authentication tab on the left navigation bar.
3. Click the blue circle next to the Via Alternative Email option. This option is available only if all of your customers have activated the Allow suppliers to use Email MFA permission.
4. Follow the instructions that appear on the next screen.
5. Input the secondary email where you want to receive the security code. This email cannot be the same login email. You need access to this secondary email in order to receive the code and use it in the system.
6. Confirm the Recaptcha shown in the modal and select the Send Code button.
7. Enter the 6-digit verification code sent to the email in the field next to the third steps shown on screen.
8. Select the Enable button at the bottom right of the window.
