Setup

Setting a reverse proxy

Setting up a reverse proxy is mandatory to expose Zero-TOTP's frontend and API.

Danger

For security reasons the reverse proxy must overwrites the X-Forwarded-For header with the real remote ip. Be careful to X-Forwarded-For that can be spoofed and must not be trusted (cf Eli's Notes). Zero-TOTP API is not meant to deals a list of forwarded IP. The reverse proxy must keep the right one.
