The favicon is the small icon displayed at the top of browser tabs and next to bookmarks.

By default, your portal favicon will be the Deskpro icon.

You can use your own favicon on the portal instead.

Note that the ICO image format commonly used for favicons is not supported. Instead, prepare a square image in PNG or GIF format that is 16x16 or 32x32 pixels.

Go to Admin > Portal and click the Change Favicon button.

Simply select your logo and then Upload your favicon file. 

Click Save  at the top of the portal editor. Your browser may take a while to update to the new favicon, but you should be able to see it straight away in the portal preview to confirm that the change worked.
