Learn how to dynamically generate Snowflake user credentials.

Infisical’s Snowflake dynamic secrets allow you to generate Snowflake user credentials on demand.

Snowflake Prerequisites

1. Open user settings

   Select the Governance & Security tab and click on Users & roles.

   
2. Create a new User

   In the top right, click Create user

   
3. Configure user details

   Create a Snowflake user with the USERADMIN role for Infisical

   

   Infisical requires a Snowflake user in your account with the USERADMIN role. This user will act as a service account for Infisical and facilitate the creation of new users as needed.

4. Create a network policy

   Programmatic Access Tokens require an attached network policy that defines the IPs allowed to authenticate as this user. Select the Projects tab and click on Workspaces to open the query editor, then paste the following snippet.

   

   CREATE NETWORK POLICY PREVIOUSLY_CREATED_USER
       ALLOWED_IP_LIST = ('0.0.0.0/0')
       COMMENT = 'Allow access from any IP';
   
   ALTER USER INFISICAL set NETWORK_POLICY = 'PREVIOUSLY_CREATED_USER';
   

   Be careful with the IPs you allow in your network policy. Using 0.0.0.0/0 allows access from any IP address, which can be dangerous in production. Prefer restricting the list to only the IP ranges that should be allowed to authenticate (for example, your corporate NAT(s) and/or Infisical’s outbound IPs if you have them).

5. Generate a Programmatic Access Token

   Select the Governance & Security tab and click on Users & roles. Then select the user you created in the previous step.

   

   Open the Programmatic access tokens tab and click Generate new token. Give the token a descriptive name and configure its expiration. Set the role restriction to USERADMIN.

   
6. Copy the Token

   Copy the generated token. Snowflake only displays it once, so store it somewhere secure for the next step.

   
7. Save the Account and Organization identifiers

   Click on the Account Menu in the bottom left and take note of your Account and Organization identifiers

   

Set up Dynamic Secrets with Snowflake

1. Open the Secret Overview Dashboard

   Open the Secret Overview dashboard and select the environment in which you would like to add a dynamic secret.

2. Click on the 'Add Dynamic Secret' button

   
3. Select the Snowflake option in the grid list

   
4. Provide the required parameters for the Snowflake dynamic secret

   Secret Name · string · required

   The name you want to reference this secret by

   Default TTL · string · required

   Default time-to-live for a generated secret (it is possible to modify this value when generating a secret)

   Max TTL · string · required

   Maximum time-to-live for a generated secret

   Account Identifier · string · required

   Snowflake account identifier

   Organization Identifier · string · required

   Snowflake organization identifier

   User · string · required

   Username of the Infisical service user

   Programmatic Access Token · string · required

   Programmatic Access Token (PAT) of the Infisical service user used to authenticate with Snowflake

   
5. (Optional) Modify SQL Statements

   

   Username Template · string · default: "{{randomUsername}}"

   Specifies a template for generating usernames. This field allows customization of how usernames are automatically created.

   Allowed template variables are:

   • {{randomUsername}}: Random username string.
   • {{unixTimestamp}}: Current Unix timestamp at the time of lease creation.
   • {{identity.name}}: Name of the identity that is generating the lease.
   • {{dynamicSecret.name}}: Name of the associated dynamic secret.
   • {{dynamicSecret.type}}: Type of the associated dynamic secret.
   • {{random N}}: Random string of N characters.

   Allowed template functions are:

   • truncate: Truncates a string to a specified length.
   • replace: Replaces a substring with another value.
   • uppercase: Converts a string to uppercase.
   • lowercase: Converts a string to lowercase.

   Examples:

   {{ randomUsername }}                                            // 3POnzeFyK9gW2nioK0q2gMjr6CZqsRiX
   {{ unixTimestamp }}                                             // 17490641580
   {{ identity.name }}                                             // <identity-name>
   {{ random 5 }}                                                  // x9K2m
   {{ truncate identity.name 4 }}                                  // test
   {{ replace identity.name '<identity-name>' 'new-value' }}       // new-value
   

   Customize Statement · string

   If you want to provide specific privileges for the generated dynamic credentials, you can modify the SQL statement to your needs.

6. Click 'Submit'

   After submitting the form, you will see a dynamic secret created in the dashboard.

7. Generate dynamic secrets

   Once you’ve successfully configured the dynamic secret, you’re ready to generate on-demand credentials. To do this, simply click on the ‘Generate’ button which appears when hovering over the dynamic secret item. Alternatively, you can initiate the creation of a new lease by selecting ‘New Lease’ from the dynamic secret lease list section.

   

   When generating these secrets, it’s important to specify a Time-to-Live (TTL) duration. This will dictate how long the credentials are valid for.

   

   Ensure that the TTL for the lease falls within the maximum TTL defined when configuring the dynamic secret in step 4.

   Once you click the Submit button, a new secret lease will be generated and the credentials for it will be shown to you.

   

Audit or Revoke Leases

Once you have created one or more leases, you will be able to access them by clicking on the respective dynamic secret item on the dashboard. This will allow you to see the lease details and delete the lease ahead of its expiration time.

Renew Leases

To extend the life of the generated dynamic secret lease past its initial time to live, simply click on the Renew button as illustrated below.

Lease renewals cannot exceed the maximum TTL set when configuring the dynamic secret.
