Changelog

1.6.0

Release date: 2026-08-07

Added

  • REST API (namespace robotstxt-2fa/v1, admin-only): GET/PUT /settings to read and update the full configuration; GET /users?role=&status= to list users with their 2FA status (enabled, configured methods, required methods, forced, frequency, preferred method, OTP configured, unused recovery codes). No secrets exposed.

Changed

  • wp 2fa list — separate Enabled, Methods, and Required columns; new --required filter.

Compatibility

  • WordPress: 6.4 – 7.1
  • PHP: 8.0 – 8.5

Tests

  • PHP Coding Standards: PHP_CodeSniffer / WPCS — 0 errors
  • PHPStan: level 9 — 0 errors
  • PHPCompatibility: 8.0–8.5 — 0 issues
  • PHPUnit: 9.6.34 — 55 tests, 140 assertions

1.5.3

Release date: 2026-08-07

Added

  • Per-user preferred sign-in method — “Preferred method” dropdown on the user profile (shown when two or more methods are enabled) lets each user pick which verification method is requested first at login.
  • Failed attempts are now cleared for the user on any successful 2FA login (email, OTP, or recovery), so no errors remain queued once they authenticate correctly.
  • GeoIP auto-download — optional “Use the free ROBOTSTXT GeoIP database” checkbox in 2FA > Settings downloads the country database from ip.robotstxt.es into the uploads directory and refreshes it daily via WordPress cron. Includes a manual “Update now” button.

Fixed

  • Security: the “Require 2FA to create Application Passwords” guard could be bypassed by requesting /wp/v2/users/me/application-passwords (the regex only matched numeric user IDs). Now accepts the me alias.

Changed

  • Role enforcement is now a floor, not a ceiling. Required methods are still forced on the profile (enforced setup), but at login users may authenticate with any method they have configured — not only the role-required ones. Fixes users who only saw email despite configuring OTP/recovery.
  • “Remember this browser” duration now follows each user’s verification frequency (daily/weekly/monthly) instead of a fixed global value, so the checkbox always complies with the profile setting.

Compatibility

  • WordPress: 6.4 – 7.1
  • PHP: 8.0 – 8.5

Tests

  • PHP Coding Standards: PHP_CodeSniffer / WPCS — 0 errors
  • PHPStan: level 9 — 0 errors
  • PHPCompatibility: 8.0–8.5 — 0 issues
  • PHPUnit: 9.6.34 — 50 tests, 121 assertions

1.5.2

Release date: 2026-06-06

Added

  • OTP import tool (2FA > Import) — import authenticator secrets from third-party 2FA plugins without requiring users to reconfigure their app:
  • Two Factor (community) — plain Base32 from _two_factor_totp_key user meta.
  • WP 2FA (Melapress) — plain or encrypted Base32 from wp_2fa_totp_key user meta; decrypted if WP 2FA is active.
  • Wordfence Login Security — raw binary from wfls_2fa_secrets table, Base32-encoded on import.
  • Admin notice banner when importable secrets are detected; dismissible per-admin for 7 days or permanently via Import page preference.
  • Import correctly skips users who already have OTP actively configured in our plugin; only imports for users who have not yet activated OTP here.

Fixed

  • Deactivating the Authenticator App method from the profile no longer pre-generates a new OTP secret immediately. The secret is deleted cleanly and a fresh QR code is generated lazily the next time the user views their profile. This ensures the import tool can correctly detect these users as candidates.

Compatibility

  • WordPress: 6.4 – 7.1
  • PHP: 8.0 – 8.5

Tests

  • PHP Coding Standards: PHP_CodeSniffer 3.13.5 / WPCS 3.3.0
  • PHPStan: level 9 — 0 errors
  • PHPCompatibility: 8.0–8.5 — 0 issues
  • PHPUnit: 9.6.34 — 42 tests, 109 assertions

1.5.1

Release date: 2026-06-06

Security

  • CSV exports use RFC 4180 encoding — fields with commas, double-quotes, or line breaks are correctly quoted. Replaces addslashes().
  • GeoIP database path validated with is_file() and !is_link() at read time to block symlink traversal.
  • robotstxt_2fa_app_password_verification_window filter return validated as a positive integer; falls back to 900 for invalid values.

Fixed

  • Export CSV button now only rendered to users with manage_options capability.

Compatibility

  • WordPress: 6.4 – 7.1
  • PHP: 8.0 – 8.5

Tests

  • PHP Coding Standards: PHP_CodeSniffer 3.13.5 / WPCS 3.3.0
  • PHPStan: level 9 — 0 errors
  • PHPCompatibility: 8.0–8.5 — 0 issues
  • PHPUnit: 9.6.34 — 42 tests, 109 assertions

1.5.0

Release date: 2026-06-05

Added

  • Full audit user table (WP_List_Table) with sortable columns, role/status filters, and CSV export.
  • GeoIP country restrictions via optional MaxMind GeoLite2 database: per-country allow list, deny list, always-challenge list.
  • Require recent 2FA verification before creating Application Passwords (REST endpoint, 15-min window, filterable).
  • WP-CLI wp 2fa export — CSV report via stdout.
  • robotstxt_2fa_force_challenge filter — override frequency skip; used by GeoIP always-challenge.
  • maxmind-db/reader added as optional production Composer dependency.

Fixed

  • Email digest cron now reschedules correctly when frequency changes (weekly ↔ monthly).

Compatibility

  • WordPress: 6.4 – 7.1
  • PHP: 8.0 – 8.5

Tests

  • PHP Coding Standards: PHP_CodeSniffer 3.13.5 / WPCS 3.3.0
  • PHPStan: level 9 — 0 errors
  • PHPCompatibility: 8.0–8.5 — 0 issues
  • PHPUnit: 9.6.34 — 42 tests, 109 assertions

1.4.0

Release date: 2026-06-05

Added

  • Audit Dashboard — top-level admin page with summary cards (total users, 2FA-enabled, recent failed attempts), failed attempts table, and 2FA status column in Users list.
  • Failed attempts log — robotstxt_2fa_failed_log ring buffer (max 100 entries) populated on every failed verification; IPs anonymized.
  • Email notifications (each independently configurable):
  • Admin-enabled 2FA: user is notified when an administrator activates 2FA for them.
  • New location login: user is notified on first successful login from an unrecognised context.
  • Recovery code used: user (and optionally site admin) notified when a recovery code is consumed.
  • Activity digest: WP-Cron weekly or monthly summary sent to administrators.
  • Application Passwords exemption: REST API clients skip the 2FA browser challenge by default.
  • IP allow list: IPs/CIDR ranges that bypass 2FA (via robotstxt_2fa_skip_challenge).
  • IP deny list: IPs/CIDR ranges blocked from login entirely (via authenticate at priority 1).
  • IPv4 + IPv6 CIDR matching (pure PHP, no external dependency).

Compatibility

  • WordPress: 6.4 – 7.1
  • PHP: 8.0 – 8.5

Tests

  • PHP Coding Standards: PHP_CodeSniffer 3.13.5 / WPCS 3.3.0

1.3.0

Release date: 2026-06-05

Security

  • TOTP replay prevention: accepted counter step stored in a 90-second transient; same code rejected on second submission within the ±1 window.
  • Login username removed from 2FA redirect URLs: robotstxt-2fa-login query parameter replaced with an opaque 32-character token resolved server-side. Username never appears in browser history, logs, or referrer headers.

Added

  • WP-CLI command family wp 2fa (loaded only when WP_CLI is defined):
  • wp 2fa status — show 2FA configuration.
  • wp 2fa enable [--method=] — enable 2FA.
  • wp 2fa disable — disable 2FA, preserving secrets and codes.
  • wp 2fa reset-recovery — regenerate and display recovery codes.
  • wp 2fa list [--role=] [--without-2fa] [--format=table|csv|json] — list users with 2FA status.
  • wp 2fa force-setup [] [--role=] [--method=] — enforce 2FA.
  • wp 2fa bypass [--days=] — grant temporary bypass (max 30 days).
