2FAuth

2FAuth is a web-based, self-hosted alternative to authenticator apps like Google Authenticator. It allows users to store, organize, and generate TOTP, HOTP, and Steam Guard security codes across devices with optional encryption and multi-user support. It can be deployed using Docker, Docker Compose, or on a standard PHP/Laravel server environment.
