Description
Clears the pre-authentication settings for either the allow or deny list.
Note
What is pre-authentication?
SharePoint includes self-issued tokens in URLs called pre-authentication URLs (also known as tempauth URLs) to provide temporary access to a SharePoint resource, which helps support more rich user experiences. For example, a common scenario is downloading a file using a URL that includes a token in the tempauth query parameter like the following:
https://<tenant>.sharepoint.com/sites/samplesite/_layouts/15/download.aspx?UniqueId=<id>&tempauth=v1.ey...
This feature is currently being deprecated and you can use the related Set-SPOTenantPreAuthSettings to control the use of pre-authentication in various use cases.
