Support » Plugin: Two-Factor » Yubikey & Codes not working at specific domain

  • Resolved doublefile23


    This plugin worked like a dream until I migrated my site from a development site at a different domain to the current site. I have used the plugin for four months with no problems on several sites.

    Neither the Yubikey nor the back-up codes work at the current site. When prompted to touch the Yubikey (it is always inserted in my desktop), there is no response and I have to rename the plugin in cPanel’s File Manager to access the WordPress dashboard.

    I have deactivated and tested other plugins for conflicts at the development site. There was no problem accessing the site during the test at the development site. I then migrated the files to the current domain and no access.

    Are there known conflicts with themes? I’m using the Astra theme with a home page created with Elementor page builder.

    There are not many options for integrating Yubikey with WordPress. I found this plugin after experiencing problems with other plugins that were abandoned or very dysfunctional.

    I don’t want my login page unprotected. 2FA through Yubikey has worked for me for several years.

    Any suggestions?

    U2F keys such as Yubikey are associated with the appId of each site, which is the hostname of your site. So after moving from a local development domain to a production domain all keys have to be registered again.

    The backup codes should work, though.


    Thanks so much! I failed to register the Yubikey in the Security Keys / register new keys section after I migrated the site.

    Lesson learned: skip a step and you are toast!
