Support to store sensitive information in SharePoint list?

Super User III
Super User III


Sharepoint has no ability to encrypt list data out-of-the-box the way it does with Data Loss Prevention (DLP) for Library files.  If the data is sensitive perhaps there is a way to store it in a separate list while linking back using a lookup column. Only trusted parties would have access to the separate list.  Unfortunately, I cannot go much further than this.  It's just an idea for you to research.

@PravK by default, if your App users have access to read/write to your Sharepoint List ... and they have access to build their own PowerApps ... then they can build their own app, link to the List and then have access to all the list information.


I've built one app where a users submit sensitive data to SP, Flow then copies that entry to another SP List [with limited access] and then deletes the entry from the 1st SP List. This way the initial users can never see the sensitive data of other users - actually they can't see any data because SP list 1 is always empty.


I have a similar situation to yours where I have a SP list getting populated by a number of users and my Accounts Dept doesn't want these users to see prices. What I planned to do is Flow entries from the 1st list to another [limited access] list which will also hold the pricing information. Maybe you could look at something similar ie quarantine your sensitive columns to a different SP List?

Turning off version history would be critical though right? Otherwise a user could just revert back to see the data.

Also, can you please correct me if I am wrong but couldn’t any user review the previous Flow history. Not the expert here. Just trying to poke holes in order to ensure the best solution for @Eelman and to learn for myself.

@mdevaney I had to go an double-check my understanding on these issues you raised! I'm not a SP or Flow expert but it's nice to know I was close to the mark.


re: versioning history in SP, our SP Developer said that once an item is deleted it's no longer able to be viewed - unless you have access to the SP Recycle Bin, which is controlled (and only accessible) by said Developer. These deleted items won't show in version history, apparently.


re: data inside a Flow, it's our understanding that only the Flow Owners / Co-Owners can see this data - or I guess the Flow administrators, once again, the above SP Developer in my org. My flows work outside of Powerapps so no issues there that I know of.


So, I think we've setup (and will be setting up) quite secure data access and flows using these processes. If anyone can poke holes in these approaches then I'd love to know about it.


Btw, I've no dramas with poking holes, I consider it the best way to learn 🙂

Hi @PravK ,

Do you want to encrypt a column in share point list, and do want it to show up within PowerApps app?


I found that you have posted same thread within this community already, please check my response within the following thread:


I afraid that there is no direct way to achieve your needs in SharePoint List. As an alternative solution, I think you could add a JavaScript Library into your SP Site to achieve your needs. Please consider take a try with the solution I mentioned above, then check if it could help in your scenario.
