説明
Yard Warden hardens core WordPress password and login flows:
- Password strength via zxcvbn-php. Scores passwords 0-4 (default 4) based on real guessability, not arbitrary character-class rules. User inputs (login, email, display name) are fed to zxcvbn so passwords containing them score lower.
- Minimum length enforcement (default 16) on top of the zxcvbn score.
- Generic login errors to prevent username enumeration on the wp-login form. Always on, no toggle. Only applies to authentication failures; password-reset and profile-update validation errors remain verbose so users can correct their input.
- Safer multisite onboarding. Auto-activates new signups server-side so no activation link is emailed and the wp-activate.php landing page (which would print username + plaintext password) is never reached. The welcome email is rewritten to contain a one-time password-reset link instead of a generated password.
- Login limiting via transient-based counters across three dimensions (IP+Username, IP, Username). Locks out brute-force attempts. Admin can clear all counters via Settings > Yard Warden.

FAQ
-
Does this add password expiry or forced rotation?
-
No. Forced password rotation is not implemented; it pushes users toward weaker, predictable passwords rather than improving security.
-
Can I disable login limiting?
-
Yes, via the
yard::warden/limit-login/enabledfilter.
