Automatically add new guest account to 2FA group

Since we want to enforce 2fa for every external user, we need to make sure that every new account is member of our 2fa group.
When a guest account is created the app adds this account to the virtual group “guest_app” automatically.
Is there a way to automatically add every new guest account to an additional group?

Hi Francesco,
I did a quick test and as far as I can see the guest app only allows for one group to be configured.
But you could use some scripting and a cron job, to add users of one group to another additional group.
