Locked out of folders because Box now asking for 2 factor authentication

I use a (free) Box account for work, and have not had issues for about 2.5 years, and then a few days ago I can no longer view/access my project folders and Box is saying that I have to set up 2 factor authentication (2FA). My company said there have been no security updates on their end that require this, and I am the only one on my project team that has had this issue on Box. Everyone else can still access the project folders (and don’t have to use 2FA). Any help?
