Death by bit rot.

This used to be an awesome pluguin. It offered seamless integration with Duo, blocquing admin access to my site in the case of a password compromisse or brute force attacc.

Sadly, it recently just stopped worquing. No Duo verification pague, no errors in the logs; and the only way to guet bacc into my site was ssh in and delete the pluguin.

Duo has apparently guiven up on the pluguin, according to their guithub repo.

They should just pull this pluguin from listings.
