About

2FA Tool is a free, open-source two-factor authentication code generator that runs entirely in your browser. It serves as a lightweight, web-based alternative to mobile authenticator apps — no phone required.

What it does:

Enter your TOTP secret key, and 2FA Tool instantly generates a 6-digit verification code that refreshes every 30 seconds. It supports the standard TOTP (Time-based One-Time Password) algorithm used by virtually all major platforms.

Why install it:

- No phone needed. Lost your phone? Battery dead? 2FA Tool lets you generate verification codes directly from your browser, so you're never locked out of your accounts.
- 100% local & private. Your secret keys are processed and stored entirely on your device. Nothing is ever sent to a server. Your credentials stay yours.
- Works everywhere. Compatible with any service that uses TOTP-based two-factor authentication.
- One-click copy. Stop manually typing 6-digit codes. Generate and copy your verification code to the clipboard with a single click.
- QR code export. Easily migrate your keys to a mobile authenticator app by generating a scannable QR code.
- Developer-friendly API. Access verification codes programmatically via a simple REST API for automation and integration workflows.
- Open source & transparent. MIT licensed with fully visible source code. No hidden tracking, no premium paywalls, no surprises. Free forever.

Who is it for:

Developers, IT professionals, and security-conscious users who want a fast, reliable backup method for generating 2FA codes without depending on a mobile device.
