Title: Stop Spammers Error with 2FA Last modified: June 29, 2020 --- # Stop Spammers Error with 2FA * Resolved [mirallesdesign](https://wordpress.org/support/users/mirallesdesign/) * (@mirallesdesign) * [6 years, 2 months ago](https://wordpress.org/support/topic/stop-spammers-error-with-2fa/) * Hi! * First of all I wanna say that I love Wordfence. * But I found a problem when trying to use Stop Spammers Plugin ([https://es.wordpress.org/plugins/stop-spammer-registrations-plugin/](https://es.wordpress.org/plugins/stop-spammer-registrations-plugin/)) * Because the Two-Factor Authentication stopped working properly. It said “VALIDATION FAILED: The 2FA code could not be validated. Please try logging in again.” And I checked it out and there’s a conflict between both plugins, so I would like how could I solve it. * Thank you very much! * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fstop-spammers-error-with-2fa%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 10 replies - 1 through 10 (of 10 total) * Anonymous User * (@anonymized-5837566) * [6 years, 2 months ago](https://wordpress.org/support/topic/stop-spammers-error-with-2fa/#post-13049762) * [@mirallesdesign](https://wordpress.org/support/users/mirallesdesign/) Thanks. We’ll see if we can get it sorted. * [@mmaunder](https://wordpress.org/support/users/mmaunder/) How exactly does your 2FA feature work? Are you using a third-party service, or does it need to phone home, or call to an external API, etc.? * If you have a list of IPs we can whitelist, that’ll probably be the easiest fix. * Thanks * [WFGerroald](https://wordpress.org/support/users/wfgerald/) * (@wfgerald) * [6 years, 2 months ago](https://wordpress.org/support/topic/stop-spammers-error-with-2fa/#post-13050191) * Hey [@mirallesdesign](https://wordpress.org/support/users/mirallesdesign/), * Thanks for sharing this.

Thanks for the fast support. * Yes it helps, the 2FA works fine now with Check Credentials on All Login Attempts disabled. * [WFGerroald](https://wordpress.org/support/users/wfgerald/) * (@wfgerald) * [6 years, 2 months ago](https://wordpress.org/support/topic/stop-spammers-error-with-2fa/#post-13053938) * Hey [@mirallesdesign](https://wordpress.org/support/users/mirallesdesign/), * Thanks for the update, and happy to hear it! * Please do let us know if anything else comes up. * Thanks, * Gerroald * [WFGerroald](https://wordpress.org/support/users/wfgerald/) * (@wfgerald) * [6 years, 2 months ago](https://wordpress.org/support/topic/stop-spammers-error-with-2fa/#post-13054328) * Hey @bhadaway, * As you’re aware, I’ve been speaking with the developers about this. We’ve noticed that you check to see if the `! class_exists( 'GoogleAuthenticator' )` which leads us to believe there was possibly a conflict with that plugin. * Our classes are namespaced, so a fix might be to check that our version constant is not set as a possible conflict fix: `!defined('WORDFENCE_LS_VERSION')`. * I hope this helps. and please feel free to reach out with any other questions. * Thanks, * Gerroald * Thread Starter [mirallesdesign](https://wordpress.org/support/users/mirallesdesign/) * (@mirallesdesign) * [6 years, 2 months ago](https://wordpress.org/support/topic/stop-spammers-error-with-2fa/#post-13054969) * Hey [@wfgerald](https://wordpress.org/support/users/wfgerald/) ! One quick question, could you please give me an email address so I can contact you to solve some questions that we have?
