Configuring User Authentication

Configure the user to use key-pair authentication (Recommended)

https://docs.snowflake.com/en/user-guide/key-pair-auth

or set the user type to be a legacy user if you wish to use only a Password for authentication (not recommended).

Set the user type to legacy using the following command

ALTER USER [kada_user] SET TYPE = LEGACY_SERVICE

From the above record down the following to be used for the setup

1. User Kada user name / Password

2. Password

3. Private Key (if configured)

4. Role

5. Warehouse

6. (If creating a new database for metadata) Database name

7. Snowflake account (found in the URL of your Snowflake instance - between https:// and .snowflakecomputing.com/…)
