Is it possible to establish a database connection to Snowflake in Looker using RSA key-based authentication instead of a password?
I believe this is planned for a mid-April launch. Keep an eye on the release notes.
Based on this https://docs.snowflake.com/en/user-guide/security-mfa-rollout Snowflake will stop supporting password auth without MFA. No way of doing this in the Looker snowflake connection as of now.
