I would be willing to assist in the design and implementation of an optional '2fa' section. While I am NOT a coder, I do have significant experience in designing and working with devs etc. to help implement such a feature. I would think that we could start off with 'easy' ones like the changing digits every x seconds (totp), and then tackle the harder ones like u2f/fido2.
I sent a request to support to offer my services and time to develop this feature. I am a 'paid' memeber and VERY happy with unraid.
