We're thinking of changing the forums software and what we're thinking of using has a 2FA option built into it already. It's much more feature complete than what I've set up here too, but the implementation is also different. That'll mean that you'll have to re-enable 2FA if/when we change the software.
What is 2FA ? What happens if we dont enable it ?
Pretty sure 2 factor is essential for security these days - Users cant be expected to enable security themselves if thats what your getting at ?
