 To use SSO authentication for Snowflake, omit a `password` and instead supply an `authenticator` config to your target. `authenticator` can be one of 'externalbrowser' or a valid Okta URL.
 
-**Note**: By default, every connection that dbt opens will require you to re-authenticate in a browser. Contact your Snowflake support rep and inquire about turning on the "id token cache" for your account as described [here](https://github.com/snowflakedb/snowflake-connector-python/issues/140#issuecomment-447028785).
+**Note**: By default, every connection that dbt opens will require you to re-authenticate in a browser. The Snowflake connector package supports cacheing your session token, but it [currently only supports Windows and Mac OS](https://docs.snowflake.com/en/user-guide/odbc-parameters.html#using-browser-based-sso-with-connection-caching-macos-and-windows-only). See [the Snowflake docs](https://docs.snowflake.com/en/user-guide/odbc-parameters.html#using-browser-based-sso-with-connection-caching-macos-and-windows-only) for how to enable this feature in your account.
