We now support two-factor authentication for new customers using Podio in a Citrix bundle: http://blog.podio.com/2017/03/20/security-features/
New customers (signing up from today) will have the ability to leverage ShareFile’s extensive security features and Single Sign-on to manage their employees on Podio.
All you need is a ShareFile account for your business (which will be helpful to back-up sensitive files) to keep track of employees and files. You can enable two-step verification, set specific password requirements or use the Single-Sign-on integration from a ShareFile Enterprise version and will automatically use the same features for Podio login.
This is a small step in the right direction and we hope to make two-factor authentication available for existing Podio customers as well in the future.
