Authica

Authica™ is a WordPress login security and login customization plugin built for site owners, agencies, and developers who want a safer, more professional login experience.

Use Authica to customize the WordPress login page, protect login forms with Cloudflare Turnstile, add two-factor authentication, reduce brute force attacks, hide or rename wp-login.php, manage login redirects, restrict login access by IP, and monitor login activity with security logs and reports.

Instead of using separate plugins for login branding, CAPTCHA, 2FA, brute force protection, login redirects, hide login, and activity logs, Authica brings these features together in one polished WordPress admin experience.

Highlights:

WordPress Login Customization

Customize the default WordPress login page with your own logo, background, colors, overlays, typography, Google Fonts, welcome messages, error messages, and responsive layout controls.

Cloudflare Turnstile Bot Protection

Protect WordPress login, registration, and password reset forms with privacy-focused Cloudflare Turnstile verification.

Two-Factor Authentication for WordPress

Add app-based TOTP two-factor authentication to improve account security for administrators, users, and client sites.

Hide or Rename wp-login.php

Move the default WordPress login URL away from automated bot targets and reduce noise from common brute force attempts.

Brute Force Protection

Limit repeated failed login attempts and help protect accounts from password guessing and credential stuffing attacks.

IP Restriction

Create allow, deny, and stealth access rules for login protection based on IP addresses or IP ranges.

Login Activity Logs and Security Reports

Monitor login attempts, blocked events, user activity, countries, IP addresses, and suspicious login behavior from the Authica dashboard.

Login and Logout Redirect Rules

Send users to the correct page after login or logout with simple redirect controls and role-based flows.

Email Verification

Require users to confirm their email address before signing in, helping reduce fake accounts, spam registrations, and bot-created users.

Modern Authica Admin UI

Manage login security and login branding from a polished, consistent WordPress admin interface built for agencies and serious site owners.

Authica Free includes full visual branding tools plus core security features. Upgrade to Authica Pro for advanced controls and premium protections.

External services

Cloudflare Turnstile (human verification)

This plugin can integrate with Cloudflare Turnstile to protect login, registration, and password-reset forms from automated abuse.

• What is it used for?
Turnstile provides a human verification widget to reduce bot signups and credential-stuffing attempts.

• What data is sent and when?
– On pages where the widget is shown, the Turnstile JavaScript file is loaded from
https://challenges.cloudflare.com/turnstile/v0/api.js. When loaded, Cloudflare
may receive standard browser/connection data (e.g., IP address, user agent, referrer)
and evaluate device/browser signals to determine risk, per Cloudflare’s documentation.
– When a verification token is produced by the widget, your WordPress site makes a
server-to-server request to:
https://challenges.cloudflare.com/turnstile/v0/siteverify
The server-to-server verification includes the user’s response token and your secret key.
When a valid client IP is available, the optional remoteip value may also be sent to Cloudflare to improve verification accuracy.

• Where can I learn more?
– Cloudflare Turnstile: https://www.cloudflare.com/products/turnstile/
– Turnstile docs: https://developers.cloudflare.com/turnstile/
– Cloudflare Privacy Policy: https://www.cloudflare.com/privacypolicy/
– Cloudflare Terms of Service: https://www.cloudflare.com/terms/

• How do I disable it?
Turnstile integrations can be disabled at Authica → Turnstile & Edge Security, which stops the
widget from loading and the verification endpoint from being called.

jsDelivr (Chart.js fallback, admin-only)

For the admin “Captcha Statistics” chart, this plugin prefers a local copy of Chart.js
(bundled in assets/vendor/chart.js/). If the local file is not present, it falls back to
loading Chart.js from:
https://cdn.jsdelivr.net/npm/[email protected]/dist/chart.umd.min.js

• What data is sent?
Only the administrator’s browser requests the static script file from the CDN.
No user content or personal data is transmitted by this plugin as part of that request.

• How do I avoid the CDN?
Keep the local file at assets/vendor/chart.js/chart.umd.min.js so the fallback is not used.

Email delivery

This plugin uses WordPress wp_mail() to send email verification messages. Mail delivery
is handled by your hosting provider or any SMTP/email plugin you configure. If you connect
a third-party email service (e.g., via an SMTP plugin), that service’s privacy terms apply.
This plugin does not send verification data to any email vendor on its own.
