Storing SAS Connection Strings in WebPart

Hello all,

I am currently writing a SPFx webpart which collects some data from the user and would put a message in Azure Storage Account Queue which will be picked up by a Function App later to be processed.

I am trying to see if it is safe to store SAS key which I will be using to put a message in an Azure Storage Queue. I am wondering if it is safe to store them within the SharePoint Framework WebPart itself or if there are any other methods which I can use. 

Regards,
Jag
