Snowflake Key Pair Authentication

Coalesce supports Snowflake’s key pair authentication for connecting Development Workspaces and Environments to Snowflake instances. Both encrypted and un-encrypted private keys are supported. Encrypted keys have a corresponding passphrase that is required to use them, while un-encrypted keys can be used directly. While keys are allowed to be encrypted with an empty passphrase by Snowflake, this is not supported in Coalesce and will result in an error.
