A2A server authentication

Hi Team,

We have created a Custom AI Agent in Elasticsearch and are planning to access it from an external application through the A2A (Agent-to-Agent) Server.

Currently, we understand that authentication to the A2A Server/API can be done using Basic Authentication with an API Key.

We would like to understand whether it is possible to use any alternative authentication mechanism instead of Basic Auth/API Key when connecting to our Custom AI Agent externally through the A2A Server as in our prod env basic auth will not be accepted as per security concerns.

Hi Team,

Can anyone help me with this query.
