## Description

2FAuth is a self-hosted two-factor authentication server and credential vault. It functions as a web-based authenticator app used to organize and generate time-based one-time passwords and other security codes for multiple accounts in a central location.

The system distinguishes itself as an API-driven security manager, allowing authentication codes to be integrated into automated workflows and external applications. It also supports shared security credentialing through the use of isolated vaults and shared folders for team collaboration.

The project covers a broad range of security and data management capabilities, including symmetric secret encryption, hardware security integration, and detailed authentication event auditing. It provides utilities for account data migration, relational data persistence, and access attempt monitoring.

Installation options include automated cloud platform deployment and support for custom path hosting.
