What is Auth'n'auth?

Question

Requesting my keys on developer.eBay, I see a message that invites me to enable OAuth. But the message also speaks about Auth'n'auth.

Searching for it on Google doesn't give me any information about what this is, so I'm asking here.

The complete message given to me by eBay is:

To use eBay's latest security features, add OAuth security to your keys. These keys will support both Auth'n'auth and OAuth.

For keys with multiple redirect URLs go to the Tokens page and enable one redirect URL for OAuth only. All redirect URLs will continue to support Auth'n'auth.

This is an old post, and I also wondered as to what this meant. It is apparently just eBay jargon for Authentication and Authorization or as eBay refers to it - Auth'n'Auth.

They have an eBay developer technical support article about this here - https://ebaydts.com/eBayKBDetails?KBid=1198

That article even shows an example usage:

<INPUT TYPE=\"submit\" NAME=AUTHORIZE VALUE=\"Launch Auth & Auth\" "
             .  "onclick=\"window.open('https://signin.ebay.com/ws/eBayISAPI.dll?SignIn&runame=$runame&SessID=$sessid');\">\n"
