DuoShieldv0.0.2

This plugin provides a straightforward two-factor authentication (2FA) system for content management system administrators, designed to enhance login security without external dependencies. It is ideal for site owners who need an extra layer of protection but want to avoid third-party apps or services.

• Email-Based Verification: After a successful password entry, the system sends a one-time code to the user's registered email address. Access is only granted after this code is correctly entered.
• Privacy-Focused Design: The system operates without relying on external authentication services, SMS gateways, or mobile apps. All verification steps are handled internally to minimize data exposure.
• Time-Limited Codes: Generated security codes expire after a short period (five minutes), reducing the window for unauthorized use if an email is compromised.
• Selective Application: The 2FA process applies specifically to standard web browser logins for the admin area. Logins from dedicated mobile apps or other third-party clients are not affected, maintaining compatibility.
• Simple Activation: The plugin requires no complex configuration. Once installed, it becomes active and begins protecting applicable admin logins immediately.
