Description

Description

Snowflake now supports Workload Identity Federation, and we want this to be usable for connections in airflow. https://docs.snowflake.com/en/user-guide/workload-identity-federation

Use case/motivation

Current snowflake connections rely on password or private key authentication. When Airflow is running in a cloud environment e.g. AWS, Azure, we want to utilise WIF connections, removing the need to manage and store long-lived credentials

Contributor guide

Research direction
Examine the existing Snowflake connection handling in Airflow (e.g., airflow/providers/snowflake/hooks/snowflake.py). Understand how password and private key authentication are implemented. Then, based on Snowflake's Workload Identity Federation documentation, design a new authentication flow that leverages OAuth 2.0 token exchange or similar. Implement the necessary changes to support WIF, including new connection parameters and token retrieval logic.
