Start With Accounts
Better authentication reduces risk more than hiding login pages alone. Review administrators, stale users, shared accounts, passwords, and 2FA or passkey adoption first.

Symptom
Brute-force protection must slow abusive login attempts without locking out real administrators or breaking integrations.
For: WordPress administrators, agencies, and site owners seeing repeated failed login attempts.
Diagnosis
What to check before changing the site
Use Measured Friction
Rate limits, CAPTCHA, IP rules, and lockouts should match the abuse pattern. Overbroad rules can block editors, clients, support, REST requests, or automation.
Protect Recovery
Every hardening step needs a recovery path. Store backup codes, confirm a site owner can regain access, and document who may disable a bad rule.
Watch Successful Logins
Blocked attempts are noisy, but successful unexpected logins matter more. Review admin activity and session history after hardening.

Diagnosis
Symptoms, causes, checks, and fixes
Symptoms
- wp-login.php or XML-RPC receives repeated failed attempts, often against common usernames.
- Administrators receive lockout notices, login alerts, or hosting resource warnings.
- Aggressive protections block legitimate admins, editors, automation, or support users.
Most Common Causes
- Public login endpoints are routinely tested with reused passwords, common usernames, and automated scripts.
- Weak administrator hygiene makes brute-force attempts more dangerous than the traffic volume alone.
- Poorly planned rate limits can create support incidents or hide real compromise attempts.
How To Confirm The Cause
- Review failed-login patterns, targeted usernames, source volume, XML-RPC activity, and whether any attempt succeeded.
- Check administrator accounts for shared users, weak recovery access, missing 2FA/passkeys, and stale agency accounts.
- List legitimate login-dependent workflows before changing firewall, CDN, or plugin lockout rules.
Fixes
- Remove or downgrade unnecessary administrators and require stronger authentication for privileged roles.
- Add measured rate limits or temporary blocks for abusive patterns while preserving recovery access.
- Document backup access, emergency login ownership, and who can reverse a bad lockout.
How To Verify The Fix
- Confirm admins can still log in from expected locations and complete recovery.
- Check that failed-login volume, targeted usernames, and lockout noise decrease after the change.
- Review logs for successful suspicious logins, not only blocked attempts.
When To Contact Support
Escalate when failed attempts become successful, hosting resources are affected, XML-RPC is required by integrations, or the site lacks safe recovery access.
