I haven't been able to find a recent answer to this exact question. I don't see anywhere that we can change this within Web App Builder.
Are we able to change the favicon for web maps, web map apps, and/or storymaps?
Hey Chelsea Dickerson,
I had a look because I though this would a reasonably easy fix however I have had very little luck! I thought it might be a setting in the json that I could edit with ArcGIS Online Assistant but no luck.
You should be able to download the application and then change the icon in the index.html in the root of the application folder. It should be around line 9 and look like so:
<link rel="shortcut icon" href="images/shortcut.ico">
You will then need to host it using your own web server.

This will download you a zip file containing the application. You will then need to unzip the application and edit the index.html file to change the favicon. Once you have changed this you will need to host the applicaiton in your own web server environment. For full list of steps you can see here: Deploy your app—Web AppBuilder for ArcGIS (Developer Edition) | ArcGIS for Developers
Unforutnately it is a long and convoluted process to just change the favicon however it does give you complete control of the application and full customisation.
You should add this capability to App Builder and/or Experience Builder! Some of Esri's configurable templates (e.g. Crowdsource Reporter) have an easy option to add favicon.
Hi I am new to using Experience Builder dev edition. Can you give me a little more direction on where and how to change the icon? I found two index.html files that have the exb.ico in them. I have changed them there but I am not seeing it reflect on my app.
