Authentication Helpers for 'Snowflake'.

snowflakeauth

snowflakeauth is a toolkit for authenticating with Snowflake. It aims for compatibility with the connections.toml and config.toml files used by the Snowflake Connector for Python and the Snowflake CLI, so that R users can use a consistent approach to Snowflake credentials across both languages.

snowflakeauth is intended for use by R package authors targeting the Snowflake platform.

Installation

You can install snowflakeauth from CRAN with:

install.packages("snowflakeauth")

Or, install the development version of snowflakeauth from GitHub with:

# install.packages("pak")
pak::pak("posit-dev/snowflakeauth")

Example

snowflakeauth can pick up on the default Snowflake connection parameters from the connections.toml and config.toml files used by the Python Connector for Snowflake and the Snowflake CLI (or any other named connection, for that matter):

library(snowflakeauth)

snowflake_connection()

snowflake_connection(name = "testing")

or you can define the parameters of a connection manually:

snowflake_connection(
  account = "myaccount",
  user = "me",
  private_key_file = "rsa_key.p8",
  private_key_file_pwd = "supersecret"
)

These parameters can then be used to retrieve credentials, which take the form of a one or more of HTTP headers:

conn <- snowflake_connection(
  account = "myaccount",
  user = "[email protected]",
  authenticator = "externalbrowser"
)

snowflake_credentials(conn)

Limitations

• Browser-based authentication is known to fail in Positron, but should work in RStudio.
