That’s not possible and also not planned. You should better think about using a second factor to secure your data access, then trying to restrict it to specific ip addresses
Actually @j-ed you have file access control. Where you can specify access by remote ip if you like.
That way you can have 2fa enabled for all accounts but extra sensitive info can be restricted to only be opened by users at the office, but they can edit everything else if they are working from home or on trips.
You’re right, I was only focused on the core functions and missed that specific app. Nevertheless pinning access to a fixed ip address seems to be counter-productive from my point of view, especially if you have to administer many users.
