Onion-Location is a new HTTP header that web sites can use to advertise their onion counterpart.
If the web site that you're visiting has an onion site available, a purple suggestion pill will prompt at the URL bar saying ".onion available".
When you click on ".onion available", the web site will be reloaded and redirected to its onion counterpart.
At the moment, Onion-Location is available for Tor Browser desktop (Windows, macOS and GNU/Linux).
You can learn more about Onion-Location in the Tor Browser Manual.
If you're an onion service operator, learn how to configure Onion-Location in your onion site.
An authenticated onion service is an onion service that requires you to provide an authentication token (in this case, a private key) before accessing the service.
The private key is not transmitted to the service, and it's only used to decrypt its descriptor locally.
You can get the access credentials from the onion service operator. Reach out to the operator and request access.

If you want to create an onion service with client authentication, please see the Client Authorization in the Community portal.
