SecondFaqtor Comments

 Beautiful little app, a throwback to how desktop applications used to be. Every other authenticator is a mobile screen shrunk down to a desktop.

 If you're on Fedora Workstation and are having trouble upgrading to the next version of your OS, please run these two commands:

 sudo rm -r /var/cache/PackageKit/*/*/RealityRipple*
 sudo wget -nv https://repo.realityripple.com/fedora.repo -O /etc/yum.repos.d/realityripple.com.repo

 and try again!
 This should solve any "Unable to upgrade to Fedora Linux: Error running transaction: package secondfaqtor is already installed" error messages.
