<h3>常見問題：</h3>
<ul>
<li><b>什麼是 2FA？</b><br>答：2FA 是指兩步驗證。在標準登入後，系統將會將一組一次性密碼（OTP）發送到您的電子郵件中。沒有該密碼，任何人都無法進入。</li>
<li><b>如何使用 Secret Login URL 功能？</b><br>答：透過 Secret Login URL 功能，可以將標準入口點（例如：wp-login.php 和 wp-admin）隱藏起來，並將其替換為自定義地址（例如：mysite.com/private-access）。</li>
<li><b>Master Switch 是什麼？</b><br>答：Master Switch 是一個智能開關，能夠在緊急情況下立即啟用或停用所有安全障礙。</li>
<li><b>DB Solution Hub 是如何工作的？</b><br>答：DB Solution Hub 通過專業的 DB Solution 套件界面進行集中管理。</li>
<li><b>如何設置 Login Monitor？</b><br>答：透過 Login Monitor 功能，您可以在每次成功登入之後收到電子郵件通知（包括 IP 和時間戳記）。</li>
<li><b>為什麼要使用它？</b><br>答：大多數自動攻擊（暴力破解）都會針對標準的 WordPress URL。通過更改 URL，並添加 2FA，您可以消除 99% 的自動化風險。</li>

原文外掛簡介
DB Solution – 2FA is a practical login security module for WordPress sites that need stronger access control without forcing every protection on by default.
It helps site owners add email OTP verification, protect the standard login path, monitor successful logins, review failed attempts, and block unwanted IP addresses from one focused DB Solution panel.
Key Features
🔐 Email 2FA – Sends a one-time code after the password step, using the WordPress email system already configured on the site.
🧭 Custom Login URL – Replaces the standard login path with a private slug chosen by the site owner.
👀 Login Monitoring – Sends an email notification after successful access, so unusual logins are easier to notice.
🧱 IP Blocking – Blocks single IP addresses and CIDR ranges from the plugin settings panel.
🧾 Access Attempt Log – Shows login attempts with credential, IP address, browser, date, and result, without storing passwords.
⏱️ OTP Countdown – Shows how long the verification code remains valid on the 2FA screen.
🛡️ Strict Mode – Can bind the OTP check to the same IP address and browser that requested it.
🎛️ Modular Controls – Every protection stays disabled after activation until the site owner chooses what to enable.
Why It Helps
Most login security tools enable too much at once or hide the important choices. DB Solution – 2FA keeps the workflow simple: activate the plugin, confirm that email delivery works, then enable only the protections the site actually needs.
This makes it useful for client sites, staging sites, and small business WordPress installs where login security must be stronger without making daily access confusing.
Email Requirement
Email-based 2FA requires a working WordPress email system. Before enabling it, send a test email from the site and confirm that users can receive the OTP code.
Compatibility
WordPress: 6.0 through 7.0.
PHP: 8.2 or later. Tested on PHP 8.4.18 in the local WordPress 7 test site.
