Customize AD FS Login Screen – Login Instructions

To customize the login instructions on your AD FS login screen, first you need to download the theme that will be updated. Then, you will update the onload.js script with your custom code, and then reset the theme to use the updated onload.js. Open PowerShell as administrator on the AD FS server, and follow these steps:

Download your theme:

export-adfswebtheme -name “<your theme name>” -DirectoryPath “<local directory>”

Modify the onload.js file located at <local directory>/script/onload.js:

Upload your modified onload.js file:

set-adfswebtheme -targetname <your theme name> -additionalfileresource @{Uri=’/adfs/portal/script/onload.js’;Path=”<local directory>/script/onload.js”}

The theme name that is delivered with the AD FS configuration is “default”, but you have the option of creating and customizing your own themes.
