## 外掛說明

Cloudusk 2FA – Two Factor Authentication is a free and easy-to-use two-factor authentication(
2FA) plugin for WordPress.

It adds an extra layer of security to your WordPress login by requiring a time-based
one-time password (TOTP) in addition to a username and password. This helps protect
WordPress user accounts from unauthorized access caused by weak or compromised passwords,
brute-force attacks, and automated login attempts.

Cloudusk 2FA uses industry-standard TOTP (RFC 6238) and works with popular authenticator
apps such as Google Authenticator, Authy, and Microsoft Authenticator. No SMS, email
codes, or third-party services are required.

The plugin is designed to be lightweight and user-friendly, with a simple setup 
process that can be completed directly from the user profile screen.

#### Features

 * TOTP-based two-factor authentication for WordPress
 * Compatible with Google Authenticator, Authy, Microsoft Authenticator, and other
   TOTP apps
 * QR code-based setup
 * Backup recovery codes to prevent lockouts
 * No SMS, email, or external services required
 * Lightweight and performance-friendly
 * Works with the default WordPress login flow
 * Fully free to use

#### Privacy

Cloudusk 2FA does not send any data to external services. All authentication is 
handled locally within your WordPress installation.
