Key Features
WP 2FA lets administrators require two-factor authentication for any combination of user roles. Users can enroll through a guided setup wizard using TOTP authenticator apps (such as Google Authenticator or Authy), email-delivered one-time codes, or backup codes for account recovery. Policies control grace periods, which roles must enable 2FA, and whether 2FA is mandatory before further access is granted.
Security Assurance
The CleanTalk Plugin Security Certification evaluation focused on the authentication flow itself: generation and storage of TOTP secrets, validation of one-time and backup codes against replay and brute force, capability checks and nonce validation on the setup wizard and policy settings, and correct enforcement of role-based 2FA policies. The review also considered email code delivery, grace-period handling, and protection of the endpoints that manage a user’s second factor.
The plugin has been successfully tested for:
✅ Information Leakage Vulnerabilities
✅ SQL Injection Vulnerabilities

Conclusion
With PSC-2026-65703, WP 2FA version 4.1.0 demonstrates strong baseline security for its two-factor authentication workflows. The certification addresses secret handling, one-time and backup code validation, request integrity on settings, and role-based policy enforcement. Site owners should enable 2FA for all privileged roles, keep backup codes in a safe place, and review enforcement policies after adding new user roles.
Note: The date and certification information may change over time. It is advisable to verify the latest details on the plugin developer’s website.
