two way authentication gone ?

Hi, I've purchased and setup R7000 with the Bitdefender Armor subscription. Now I decided to check the protection status and discovered that everything has changed.

1. Two way authentication in Netgear has gone. This feature seems to have completely disappeared from Netgear. Is that correct? 
2. I believe there was a link in Netgear to the Armor portal, not found in the Netgear account  anymore. Eventually I found it https://armor.netgear.com/support at https://www.netgear.com/support/product/netgear-armor.aspx  But bizarrely this link signed as ‘Log in to NETGEAR Armor portal to access support articles on NETGEAR Armor and Bitdefender Total Security’ . There are no support articles in the portal.
3. I still cannot find details for the account. It is missing from Netgear and Armor portal. There is a subscription read only information in Netgear on what devices I have and expiry date. But how to extend or cancel a subscription or change payment methods ?
