Under development.
Right now, only key pair authentication is supported.
Add your public and private key under environment_variables/local folder (you will have to create the local folder). Make sure your private key is named rsa_key.p8 and your public key is rsa_key.pub.
You can change the text files in environment_variables/snowflake_private_key_path.txt and environment_variables/snowflake_public_key_path.txt to change where the application looks for the keys.
