Hey, that's a good question and a valid concern. Teleport's auth server is designed to be extendable and we plan to add support for a variety of existing authentication and authorization protocols in the upcoming releases based on community feedback and requests. We use existing 2FA HOTP based access control in the first release mostly to get a good quick start experience and we understand that big organizations will plug in Teleport into their existing auth infrastructure.
