Frequently asked questions
Will this slow down my website?
No. Only required components are loaded. Most package size comes from templates, images and supporting resources, while actual runtime execution remains compact.
Does it support SMS or WhatsApp OTP?
Currently, only Email OTP authentication is supported. Multi-channel OTP verification (Email/SMS/API) is planned for future releases.
Can guest users verify or register using OTP?
Yes. Guests can register and verify their email using OTP without requiring a password.
Can administrators log in using OTP?
Yes. Administrators can securely log in to the WordPress dashboard using Email OTP authentication.
Can I use multiple inline or popup forms on the same page?
Yes. You can place multiple inline or popup authentication forms on a single page using shortcodes.
Can I enable Two-Factor Authentication (2FA) for login or registration?
Yes. 2FA can be enabled for login, registration, or both to add an additional layer of protection.
What happens if 2FA verification fails?
If verification fails, the user will be redirected to the configured failure redirect URL or verification page based on plugin settings.
Where does the user go after successful 2FA verification?
After successful verification, users are automatically redirected back to their original source or intended destination page to ensure a smooth authentication flow.
Can I enforce verification when a new device is detected?
Yes. The Dynamic Session Shield security engine can enforce verification when a new device or browser session is detected.
What happens if a session becomes inactive?
The session will be locked after the configured inactivity period or unusual activity is detected and verification will be required to continue access.
Can the plugin log out active sessions on suspicious activity?
Yes. Dynamic Session Shield can automatically terminate sessions if verification fails.
Does session protection affect all logged-in devices?
No. Session protection applies only to the current session unless global logout is triggered by security rules.
Can I customize the 2FA verification page?
Yes. You can define a custom page containing the verification shortcode to control the verification workflow.
Can I disable the session inactivity timeout?
Yes. The inactivity timeout can be disabled or adjusted from plugin settings.
Is Dynamic Session Shield enabled by default?
No. Dynamic Session Shield is optional and can be enabled or configured from the plugin settings.
Can developers integrate authentication responses into custom workflows?
