Two-factor-authentication for Utilities

With a few exceptions, ThingWorx Technology offers pretty solid security, so that we now focus on securing processes around the applicatio, and we all know the user's behavior is most difficult to secure.

One of our feature requests was already added, UTL-4068 will allow the User to change the password in the login screen and password changes will be able to "force" a certain amount of Password security (e.g. >64 bit).

While strong passwords are more difficult to hack, strong passwords will lead users to store credentials in their browser out of mere convenience. That's why I wanted to ask this community:

• Is there an easy way to create a two factor authentification with a message code?
• Could the Trello extension be updated so this could be supported?
• Did anyone implement this?
