Toofer

Toofer is a local-first, web-based two-factor authentication app that stores your TOTP secrets directly in your browser. Private, simple, fully offline.

Open source alternative to:

Google Authenticator

Microsoft Authenticator

Authy

Toofer is a local-first, web-based two-factor authenticator application built with Svelte. It generates time-based one-time passwords (TOTP) for securing online accounts without relying on cloud services. Being local-first means your 2FA secrets never leave your device unless you choose to sync them.

The app provides a clean, modern interface for managing multiple authentication codes across different services. As a web-based tool, it runs directly in your browser while keeping all data stored locally. This approach eliminates the risk of vendor lock-in or service shutdowns that plague proprietary authenticator apps.

Compared to paid alternatives like Google Authenticator or Authy, Toofer offers complete transparency through its open-source codebase and gives you full control over your 2FA data without ads, tracking, or subscription fees.
