Are you able to get into the account at all?

In the article posted December 12th [https://fresh-hotel.org/articles/937-recent-changes] a little blurb at the bottom says..

8) Ability to enable authentication system / disable has been made easier via account settings on homepage. (We recommend everyone with a smart phone to set it up ASAP)

I'm not sure about the system, since i'm tech challenged and would die if I enabled it. Hope this possibly helps.
