This plugin enhances the security of your WordPress website by adding a simple but effective two-factor authentication (2FA) screen after a successful password login.
Instead of adding fields to the main login page (which can cause conflicts), this plugin waits until a user has correctly entered their username and password. Then, it intercepts the login and presents them with a clean, separate screen to enter their 6-digit code from an authenticator app (like Google Authenticator, Authy, etc.).
This method is more secure, more compatible, and provides a smoother user experience.
Features:
Secure Post-Login Verification: 2FA check happens on a separate screen, after the password is correct.
Easy Setup: A simple “Usama 2FA” menu page for each user to scan a QR code and activate 2FA.
Backup Codes: On activation, 10 one-time-use backup codes are generated in case you lose your phone.
Regenerate Codes: You can generate new backup codes at any time from the settings page.
Lightweight & Simple: No bloat. Just the essential 2FA features.
Per-User: 2FA is enabled on a per-user basis. Administrators cannot control 2FA for other users.
<h3>External services</h3>
This plugin connects to a third-party API to generate the QR codes used during setup.
Service: goqr.me API (https://www.google.com/search?q=api.qrserver.com)
Usage: Used only once during setup to generate a QR code image that users scan with their authenticator app.
Data Sent: The API receives the user’s email address and the generated secret key (inside the OTPAuth URL) to create the image. This data is not stored by the service.

This is awesome plugin!
It has all the features I need and is very easy to use.

Awesome!

長年、SiteGuardを使っていましたが、たまにログインできなくなってプラグインをサーバーから削除とかしたりだったので、こちらのプラグインを使い始めました。
設定画面もわかりやすく、作動も安定していて、ログイン試行履歴とかも見れます（結構不正ログインされようとしているのがわかって楽しい）、随時他のサイトのセキュリティプラグインもこちらに切り替えていこうと思っています。感謝感謝
