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.
Web Application Firewall
Inspect incoming requests for suspicious patterns such as SQL injection, cross-site scripting, path traversal, remote code execution, sensitive file probes, scanner traffic, and known malicious user-agents.
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.
– If you enable the optional Turnstile Analytics feature, the site sends an authenticated request to
https://api.cloudflare.com/client/v4/graphql to retrieve aggregate Turnstile event counts.
The request includes the configured Cloudflare account ID, date range, and account API token.
• 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 and optional analytics can be disabled at Authica Turnstile & Edge Security, which stops the
widget from loading and the related service endpoints from being called.
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.
