原文外掛簡介
Automated bots probe WordPress logins and forms around the clock. Ultimate Security shuts that down — with two-factor authentication, brute-force lockouts, anti-spam CAPTCHA, a hidden login URL, session controls, vulnerability scanning and Cloudflare edge rules — all from a clean dashboard you do not need to be a security expert to run.
🎥 Watch a 2-minute intro:
🛡️ Lightweight. Privacy-first. No bloat.
Why Ultimate Security?
It just works. Sensible defaults out of the box — turn it on, you are safer in minutes.
Nothing is guessed. A guided setup scans your site first, shows you every change before it happens, and can undo all of it.
Built for real attacks. Stops the automated login, brute-force and spam traffic that actually hits WordPress sites.
Zero learning curve. Plain-English settings, and a Test Mode to preview rules before they go live.
Privacy-respecting. No product-usage telemetry and no hidden phone-home tracking. Pro features are clearly labelled.
🚀 Guided setup in about 3 minutes
Five short steps — tell us about the site, we run a quick automatic check, you pick one protection template, then review and apply.
See every change before it happens. The wizard shows a full diff of what it will change.
Undo all setup changes afterwards, without overwriting edits you made yourself.
Seven templates to start from: basic, moderate, strict, agency, blog, membership and WooCommerce.
An emergency access link is shown during setup — save it, and you can deactivate the plugin from a browser if you ever lock yourself out.
🔐 Two-Factor Authentication
Email one-time codes — no app required, works for every user.
Authenticator apps — TOTP and HOTP, compatible with Google Authenticator, Authy, Microsoft Authenticator and others, with QR-code enrolment.
Per-user setup with role-based configuration — decide which roles use email codes and which use an authenticator app.
Built-in rate limiting on code entry, with a configurable attempt limit and lockout.
2FA event logging you can switch on or off.
Works with your login flow — WordPress, WooCommerce and Ultimate Member login forms, plus a setting for XML-RPC requests.
🚪 Login access control
Custom login URL — move wp-login.php to a secret address so bots cannot find it, with a configurable post-login redirect.
HTTP Basic Authentication — put a second password wall in front of wp-login.php and wp-admin, with no .htaccess editing. The password is stored hashed, repeated failures trigger a lockout, and you can allow trusted IP addresses straight through.
Login page consent notice — display your own consent or policy text on the login form.
🔑 Password policies
Enforce minimum length, mixed case, numbers and special characters, or start from a preset.
Password expiry with advance warning, a grace period and email notification.
Password history so old passwords cannot be recycled.
Force a password change on first login.
Refuse compromised passwords — checked against the Have I Been Pwned Pwned Passwords range API using k-anonymity, so the password itself never leaves your site.
Optionally disable self-service password reset and point users at your own instructions instead.
🛑 Brute-force protection
Limit failed login attempts and lock offenders out automatically.
Progressive lockouts — repeat offenders get longer lockouts.
Configurable retry-reset window, and a permanent block list for persistent offenders.
One-time recovery link so a lockout never leaves you stranded.
👥 Session management
Limit concurrent logins per user, and choose whether to block the new login or sign out the oldest session.
Idle timeout for inactive sessions.
Harden auth cookies with HttpOnly, Secure and SameSite flags.
Bind a session to its IP address and/or browser to detect session hijacking.
🤖 Bot & spam protection
Google reCAPTCHA v2 and v3 — including a v3 score threshold, IP and user-agent allowlists, a bypass for logged-in users, and a log of recent verifications.
Cloudflare Turnstile — with theme, size, language and appearance options, deferred script loading, custom failure messages and its own log.
Form coverage for both providers: WordPress login, registration, lost-password and comment forms, plus WooCommerce login, registration, lost-password and checkout forms.
No-conflict mode and provider priority so two CAPTCHAs never render on the same form.
Key verification — validate your site and secret keys from the settings page before going live.
Outage handling — if the CAPTCHA provider is unreachable, your forms keep working.
🔎 Vulnerability scanning
Scan WordPress core, plugins and themes for publicly known vulnerabilities.
No API key required. The scanner uses the keyless WPVulnerability database by default.
Optionally add a WPScan or Patchstack API key for additional coverage, with automatic failover between providers.
Scheduled scans with email alerts, filtered by the severity you care about.
Abandoned plugin detection — flags extensions that have not been updated in a long time.
Scan history, comparison between runs, and an ignore list for findings you have accepted.
Results surface where you already look: Site Health, the WordPress dashboard widget, the plugins list table and menu counters.
☁️ Cloudflare WAF rules
Connect your own Cloudflare account and manage edge rules from wp-admin:
Allow good bots — keep verified search, monitoring, backup, SEO and social crawlers working.
Block aggressive crawlers and sensitive WordPress paths.
Block web hosts and TOR exit nodes.
Challenge large cloud providers and selected countries.
Challenge VPN traffic and requests to wp-login.php.
Virtual patches — block requests exploiting known WordPress core CVEs at the edge until you can update.
Preview the generated rule expressions before you deploy anything, review the live rules on your zone, and see request, threat and bandwidth analytics.
🧂 WordPress security keys (salts)
Rotate the security keys and salts in wp-config.php on demand or on a schedule — daily, weekly, monthly, quarterly or twice a year.
Advance notification before a scheduled rotation, so a forced re-login is never a surprise.
Quiet hours, plus pause and skip-next controls.
Rotation history with the ability to restore a previous set of keys.
🔄 Update Manager
Set auto-update policy for WordPress core, plugins and themes, with per-plugin and per-theme overrides.
Update windows and allowed days, plus freeze periods for the times you do not want anything changing.
Delay updates by a set number of days to let others find the bugs first.
Optional maintenance mode during updates, and detection of version-controlled installs.
Email notifications and a daily digest.
📊 Monitoring, Security Score & logs
Security Score — a scored posture with a per-check breakdown showing exactly what is holding the score down.
Activity log — successful and failed logins, logouts, lockouts, 2FA events and password events, with a configurable retention period.
Session log for session events and anomalies.
Who’s online — see which users are active right now.
WordPress core file integrity check — verify core files against the official WordPress.org checksums.
Site Health integration — plugin, server, database, filesystem, theme and WordPress diagnostics added to the Site Health screen.
Dashboard widget summarising failed logins, issues found, outdated plugins and your current score.
🧪 Test Mode
Simulate your security rules without blocking anyone.
Review a log of exactly what would have been blocked before you enforce it.
Choose which roles are affected, and keep administrators excluded.
An admin-bar indicator and dashboard notice make sure you never forget it is on.
🧰 Tools, migration & backup
Migrate from Wordfence Login Security — preview what will be imported, run it, and roll it back if you change your mind.
Export and import settings as JSON for staging-to-production moves or disaster recovery.
Reset all settings back to defaults, and clear the plugin cache.
Diagnostics — REST API status, cron status with a manual run trigger, and server status.
Emergency deactivation URL — a secret link that switches the plugin off if you are locked out.
🧩 Works with what you already run
Ultimate Security detects and adapts to WooCommerce, Ultimate Member, popular page builders, form plugins, caching plugins and SEO plugins, and warns you when another security plugin is doing the same job.

🛠️ Recommended setups by use case
Different sites face different threats. Start with the profile that matches you, then layer on more from the documentation.
Solo blogger / personal site — Enable Email 2FA on the admin account, set a 5-attempt login lockout with a 15-minute cooldown, set a custom login URL, and add Cloudflare Turnstile to the comment form.
Small agency / multi-author site — Require authenticator-app 2FA per role for editor and above, enforce password length + history, cap concurrent logins per user, and enable Test Mode before tightening rules.
WooCommerce store — Add reCAPTCHA or Turnstile to login, registration, lost-password and checkout forms, set a custom login URL, enable brute-force lockout, and run a vulnerability scan weekly.
Membership / community site — Per-user 2FA enabled site-wide, strong password policy, session limits to block account sharing, and CAPTCHA on registration to keep bot signups out.
Every setup above uses only free features. See the full setup guides for step-by-step instructions.
📖 Security terms in plain English
New to WordPress security? Here is what the jargon means and why each one matters.
Two-Factor Authentication (2FA) — A second proof of identity (a one-time code) on top of your password, so a stolen password alone cannot log in.
Brute force — Automated tools that guess thousands of password combinations against your login form; lockouts cut them off after a few failures.
CAPTCHA — A small puzzle or invisible check that confirms a real human is filling out a form, blocking most spam bots.
Custom login URL — Moving your login page from the well-known /wp-login.php to a secret path so automated scanners cannot find it.
Vulnerability scanning — Checking your installed plugins, themes and WordPress version against public databases of known security flaws, so you learn about a problem before an attacker uses it.
Virtual patching — Blocking the specific requests that exploit a known flaw at the network edge, which buys you time when an update is not available yet.
Salt rotation — Replacing the random secret keys in wp-config.php to invalidate stolen sessions and force re-login everywhere.
Session control — Limiting how many places one account can be logged in at once and hardening the auth cookie.
Test Mode — Previewing which requests a new rule would have blocked, before the rule starts blocking anything for real.
