+And if you want connect Snowflake with [Key Pair Authentication](https://docs.snowflake.com/en/user-guide/key-pair-auth.html#step-6-configure-the-snowflake-client-to-use-key-pair-authentication).
+Plase make sure you have the key pair and the public key is registered in Snowflake.
+To connect Snowflake with Key Pair Authentication, you need to add the following parameters to "SECURE EXTRA" field.

+***Please note that you need to merge multi-line private key content to one line and insert `\n` between each line***
