Can you add a forum option for force use to two step verification? as you know we can make this for admin panel but we cant set it to each forum seperately?
As we already have this covered in permissions -- which would allow you to require it for particular users or for the whole community -- I don't think we would add a further/separate option for this.
As @Martok mentioned, you can set the permission for users that have access to the privileged information and ensure they enable 2 step before continuing.
I provided working groups in my forum. for example graphic, social media etc. I associated this to custom profile fields.
What does it mean. Users can join to working groups who want to work specified working group and I dont want to change his usergroup for attent to working group.
I am making distinction working groups from usergroup with custom profile field. in a word I dont change user's usergroup.
as @Mike said we are using 2 step verification all forum. I think this suggestion isnt hard to provide.
Each working group would have a user group associated to them, so Graphics would have a Graphic user group, Web Coding a web coding user group etc. A user group promotion would assign them to each user group (as a secondary user group) automatically.
If a user 'joins' the Graphic working group, then you would give the Graphics user group access to specific private forums. You would also enable 2 step verification for that user group. Similarly for Web Coding and the other groups.
Note that these user groups are in addition to any others that they are in (and of course Registered should be the primary user group for every member on the website). Members can be in multiple user groups.
