I wish it had a feature in the admin section where one could disable different 2FA methods. For example, in my family everyone has SMS as a 2FA, as well as hardware tokens and device prompts. SMS was there from the beginning, so everyone has it activated. Only one account is not using hardware tokens.
So what I'd like to do is to set SMS to off, and all the accounts which already have something like device prompts and/or at least one hardware token added, get SMS deactivated without user intervention.
