As the title says. We need to use Duo 2FA Integration. As we understand it, there is a change required to be made to the core in order to use an existing Duo 2FA app. We have already put a bounty on the integration here. As I understand it, it’s not overly complicated but needs a change to the core to support a custom CSP. https://www.bountysource.com/issues/47931501-any-chance-of-integrating-duo-as-a-two-factor-provider
It has been suggested to use competing software, but quite honestly I would rather put the bounty into Nextcloud and see if we can’t get it done.
