The TFA documentation page ( https://www.drupal.org/node/1663240 → ) claims that this module supports HybridAuth. I'm pretty sure that this is incorrect as during my testing, when I login using a HybridAuth account the TFA module is asking me for my password to 'Set up application" (bad wording?/what does that mean). I of course don't have a password because I'm using HybridAuth! So this either needs to be fixed (only ask for a password for local accounts?) or remove the claim of HybridAuth support.
