Overview

To authenticate with Snowflake (JWT), you need:
  1. Subdomain - The subdomain for your Snowflake account, typically part of the account URL (e.g., xy12345 in xy12345.snowflakecomputing.com).
  2. Account Identifier - The unique identifier for your Snowflake account.
  3. User Name - The Snowflake username used to authenticate with the account.
  4. Private Key - The private RSA key in PEM format used to sign your JWT for authentication. It corresponds to the public key registered in Snowflake.
  5. Fingerprint - The SHA-256 fingerprint of the public key used to authenticate with Snowflake, generated after uploading the public key to your account.
This guide will walk you through obtaining and generating these credentials within Snowflake.

​
Prerequisites:

  • You must have an account with Snowflake (JWT).

​
Instructions:

​
Step 1: Finding your Subdomain

  1. Log in to your snowflake account.
  2. Click on your account profile in the bottom-left corner, then under Account, select the account you wish to connect to.
  1. Click on View account details for the selected account.
  2. A pop-up window will appear displaying all your Account Details.
  3. Your Subdomain is the part before snowflakecomputing.com in the Account/Server URL field. For example, in KXOPMLU-RE00572.snowflakecomputing.com, the subdomain is KXOPMLU-RE00572.

​
Step 2: Finding your Account Identifier

  1. From the same Account Details table above, your Account Identifier will be displayed within the Account Identifier field.
If you are using the account locator, exclude any region information from the account locator to obtain the Account Identifier. This value should be provided in uppercase.

​
Step 3: Finding your User Name

  1. From the same Account Details table above, your User Name will be displayed within the User Name field.
This value should be provided in uppercase.

​
Step 4: Generating your Private Key

  1. Generate the RSA private key with the following command:
openssl genrsa -out rsa_key.p8 2048
  1. Extract the corresponding public key:
openssl rsa -in rsa_key.p8 -pubout -out rsa_key.pub
  1. To view the Private Key, run the following:
cat rsa_key.p8

​
Step 5: Finding your Fingerprint

  1. From your Snowflake account, navigate to Projects > Worksheets then click on the + button from the top right corner.
  1. Run the following SQL command to assign the Public Key to your user:
ALTER USER <your_username> SET RSA_PUBLIC_KEY = '<public_key_contents>';
public_key_contents refers to the public key generated in the previous step. You can use cat rsa_key.pub to view contents.
3. After assigning the public key, run the DESCRIBE USER command to check if the public key fingerprint has been set: 
DESCRIBE USER <your_username>;
  1. Look for the RSA_PUBLIC_KEY_FP property in the output. It should show the Fingerprint of the Public Key you just assigned. The Fingerprint is typically in SHA-256 format (e.g., SHA256:<fingerprint>).
Once you have your Subdomain, Account Identifier, User Name, Private Key and Fingerprint:
  1. Open the form where you need to authenticate with Snowflake (JWT).
  2. Enter your Subdomain, Account Identifier, User Name, Private Key and Fingerprint in their designated fields.
  3. Submit the form, and you should be successfully authenticated.
You are now connected to Snowflake (JWT).
