We enable 2FA on all registered Phone Numbers by default as it provides an extra layer of security.
Permissions
2FA can only be disabled by an Administrator of the Meta Business Portfolio, a User assigned access to the WhatsApp Account (asset) or an authorised Tech Provider.
360dialog, as a Business Solution Provider (BSP), cannot disable 2FA at the request of unauthorized users.
Steps to disable
Go to Meta Business Manager > WhatsApp Manager> Phone Numbers > Settings
Select Two-Step Verification, then click on Turn off two-step verification
An email with a link will be sent to the email address associated with the business portfolio.
Use the link to disable two-step verification.
