## What it is
2FAuth is a self-hosted web application for managing Two-Factor Authentication accounts and generating TOTP, HOTP, and Steam Guard security codes from any browser. It serves as an open-source alternative to proprietary authenticator apps like Google Authenticator, with QR code scanning, encrypted storage, and multi-user support.

## Use cases
- self-hosted alternative to google authenticator
- generate 2fa codes from desktop browser
- backup and restore two-factor accounts
- manage totp and hotp tokens in one place
- share 2fa codes across a team
- scan qr codes to add otp accounts
- store 2fa secrets encrypted in own database
- get otp codes without taking out smartphone

## When to choose
- you want your 2FA secrets out of a single phone and in a self-hosted, backupable database
- you need OTP codes on desktop as well as mobile
- you want a team or family to share access to 2FA accounts with isolated vaults
- you prefer open-source, self-hosted tools with encryption and WebAuthn/security-key login

## When to avoid
- you want a simple phone-only authenticator with no server to maintain
- you are not comfortable self-hosting and securing a web app (HTTPS, backups of APP_KEY)
- you need offline code generation with no network access
- you require enterprise-grade multi-tenant 2FA management
