Add Privacy Link
Applies To: Windows Server 2016, Windows Server 2012 R2
To add the privacy link that is displayed on the sign-in page, use the following Windows PowerShell cmdlet and syntax.
Set-AdfsGlobalWebContent -PrivacyLink https://fs1.contoso.com/privacy/ -PrivacyLinkText Privacy
linkText parameter in this cmdlet is not required unless you use another value than the default, which is Privacy. The advantage of using the default is that the pages are localized to all client locales. After the sign-in page is customized, the customization takes precedence; therefore, you should customize for all languages that you want to support. All customized content takes a locale parameter. When you configure localized content, you should configure it with a country-less locale first, for example, "en", before you configure country and region-specific locale, such as "en-us".
