常见问题:
What if I get locked out of my site?
Guard Dog includes a temporary access feature that generates secure bypass links. These can be created before lockout occurs. If you're already locked out, you can disable the plugin via FTP by renaming the plugin folder.
Which CAPTCHA provider should I choose?
- Google reCAPTCHA v3 - Invisible, best user experience
- Google reCAPTCHA v2 - Checkbox verification, widely supported
- hCaptcha - Privacy-focused alternative to Google
- Cloudflare Turnstile - Fast, privacy-first option
Is two-factor authentication required?
No, 2FA is optional but highly recommended. It can be enabled per-user and includes recovery codes for backup access.
Will this affect my site performance?
Guard Dog is optimized for performance. Features like database query optimization and intelligent caching ensure minimal impact on your site speed.
I'm getting false "IP shift" alerts showing the same IP for every user
This happens when your site is behind a reverse proxy, CDN, or load balancer (common with hosts like Kinsta, WP Engine, Cloudflare, or AWS). The proxy sits between users and WordPress, so Guard Dog sometimes detects the proxy's IP instead of the real visitor's IP. To fix this:
- Go to Guard Dog > Sessions > Settings
- Scroll to "Reverse Proxy / Load Balancer"
- Set "IP Detection Method" to match your setup:
- Cloudflare - if your site uses Cloudflare (most common)
- X-Forwarded-For - for most other proxies (Kinsta, WP Engine, Nginx, AWS ELB)
- X-Real-IP - if your server uses Nginx as a reverse proxy
- Auto - tries all headers automatically (default, works for most sites)
- REMOTE_ADDR only - only use if you have NO proxy (direct connections only)
- Add your proxy's IP addresses to "Trusted Proxy IPs" (one per line, CIDR ranges supported)
- Check the "Detected IP" row to verify your real IP is shown, not the proxy IP
How do I find my proxy's IP address?
If you're seeing false IP shift alerts, the alert email will contain the proxy IP (the "new IP" that keeps appearing). You can also check the "Detected IP" row on the Sessions settings page - if it shows your proxy's IP instead of your real IP, that IP should be added to the Trusted Proxy IPs list. Common proxy IP ranges:
- Cloudflare - see Cloudflare's IP ranges
- Kinsta - typically a Google Cloud IP (e.g., 34.x.x.x or 35.x.x.x)
- AWS ELB/CloudFront - check your AWS console for load balancer IPs
- Private networks - 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16
Does it work with other security plugins?
Guard Dog is designed to work alongside other security plugins, though we recommend testing in a staging environment first to avoid conflicts.
What external services does Guard Dog use?
- CAPTCHA (when enabled): Google reCAPTCHA, hCaptcha, or Cloudflare Turnstile.
- Email (when Email 2FA enabled): Amazon SES, Mailgun, Resend, SendGrid, or Google SMTP.
- Social Login (when enabled): Google OAuth, Microsoft Azure AD, and Apple Sign In (authorization and user profile).
- IP Reputation (when enabled): DNS only: Spamhaus ZEN, CBL (abuseat.org), dan.me.uk (Tor). Optional geo: ip-api.com or ipinfo.io; geo can be turned off to use only DNS.
- Geolocation (country from IP): When CDN/proxy headers do not provide country, ip-api.com or ipapi.co may be used (e.g. access control, activity log).
