Our verdict on GAuth

GAuth is a web-based authenticator for people who need time-based one-time passwords without broader account-management features. It lets users add accounts with a name and secret key, generate six-digit TOTP codes, delete stored accounts, and export account data as JSON. The application is available as a hosted web app and can also be served as static files from a web server. Its GPL license and self-hosting option make it suited to users who want a narrow authenticator that can fit into their own web environment.

The main consideration is how GAuth stores and moves account data. Accounts are kept in browser LocalStorage, while JSON export provides a way to save the account data outside the application. The published feature set does not include encrypted backup or multi-device synchronization, so the workflow is centered on the browser where the accounts are stored and on manually managed exports. That keeps the product focused, but it also makes storage and portability decisions important for anyone managing several devices or seeking a managed backup process.

GAuth’s platform fit is intentionally narrow: it supports the web and self-hosted static-file deployment, and its authentication method is TOTP. It does not provide push approvals or team administration, so it is better suited to individual users and small, self-managed setups than to organizations that need centralized controls. Choose GAuth if browser-based TOTP, JSON export, open-source distribution, and self-hosting match your requirements. Choose an alternative if you need encrypted backup, synchronization across devices, push-based approval, or administrative features for teams.
