Hi @cskin,
Welcome to the Community! I am very sorry to hear about the long wait time you have had with this issue.
Since this relates to your account’s 2 factor authentication, we would suggest reaching out to your amazing Support Team to resolve. If you were having difficulty accessing your account, you can also submit a request using this form linked in the Unable to Log Into Your Klaviyo Account? section of the How to Contact Support Help Center article.
Disabling 2FA is something that you can do within your own account!
If you are the Owner or Admin of a Klaviyo account, you have the ability to require two-step authentication for all users on your account. Navigate to Account > Settings > Users and check the box to Require two-step authentication for all users.

Existing users will be required to enable two-step authentication on their next login. New users will be required to enable two-step authentication when creating their user login.
If you decide to no longer require two-step authentication for all users, you can uncheck the setting at any time. Any users that already have two-step authentication enabled will remain in that state. Users will still have the option to enable two-step authentication for their individual user account.
Have a good rest of your day!
Alex
