Hi Shane, 

If you have multi-account access on your credentials and one of the accounts you are on has two-factor authentication required, it will apply to all of the accounts you log into through those credentials, not just the account that requires it. Since the accounts are linked, you will need to have two-factor authentication turned off on all the additional accounts in order for it to stop requiring it upon logging in. 

You can learn more about these Account Settings here. 

I have same problem and I ONLY HAVE ONE ACCOUNT.

How do I turn it off?

Hello @TBW,

If you are the owner of the account, you can disable the two-factor authentication requirement by navigating to Account > Settings > Users and un-checking the box to Require two-step authentication for all users. 

Should you need additional assistance in disabling your two-step authentication method or resetting it, I would recommend reaching out to support to have a closer look at your account and process this request since it does pertain to sensitive account information. 

Hope this helps!

David
