## What it is
GAuth is a browser-based multi-factor authentication app that implements the TOTP (RFC6238) algorithm to generate one-time passwords, built with HTML, jQuery Mobile, jsSHA, and LocalStorage. It can be used as a hosted web application or self-hosted by serving static files.

## Use cases
- generate TOTP one-time passwords in the browser
- replace Google Authenticator with a web app
- self-host a two-factor authentication token generator
- get 2FA codes without installing a mobile app
- store TOTP accounts locally in the browser
- use two-factor authentication on desktop

## When to choose
- you want a lightweight browser-based TOTP generator
- you prefer self-hosting static files over installing an app
- you need 2FA codes on a device without a native authenticator app

## When to avoid
- you need encrypted or hardware-backed secret storage
- you require a maintained app with active security updates
- you need HOTP counter-based tokens or advanced authenticator features
