Power Apps: How To Block Users From Using An App

Power Apps: How To Block Users From Using An App

Hey Everyone,
Thanks to the combination of Power Apps Office365Groups and StartScreen function, you can now control which users accessing the app also have rights to the backend SharePoint data source.

In this video, we'll take a look at a scenario where users who have access to the app but do not have access to the backend SharePoint site are automatically re-routed to a denied screen. This is accomplished using a combination of IsEmpty, Filter and User functions.

Thanks Daniel, that's a very well preented and useful solution. It allows the developer to move data sourcing to the onvisible event(s) which only fire for authorised users, and thus avoids the generationof ugly error mesages. Perfect. Good work 🙂

Happy Independence Day! Thanks for another great video... Question about the mail value in the Office 365 groups - is that the UPN, or the email address?

Thanks! Most of them I’m bothered by the opposite. Is there is way to grant access to the app AND the Sharepoint list at the same time without having to add groups to both (I have a few lists it’s annoying to set up).

Daniel, good evening. Do you know if it's possible to prevent users to create a powerapp based on the list that has been shared with them?

It's crazy. You pit this huge amount of effort into creating user experiences, applying business rules, and there's nothing stopping users from just create a simple power app, adding a list and a form and bang, they can do as they please, if you don't have stuff like item level security.

Thanks in advance

I thought I'm just a common user in my company and may not be allowed to see user or group id in Azure AD. Surprisingly, I can! Hope our IT won't block this function to us.^^

You do not need to write "IsEmpty()=true" in condition, because IsEmpty already returns true or false.

I'm a bit confused, why would you want to block users? They would already be denied access if you don't share the app with them.
