How To

Address upcoming MFA enforcement for Snowflake connections

Environment

Snowflake

Prerequisites

Snowflake admin access

Procedure

To enhance security, Snowflake will fully deprecate Basic Authentication (username/password) by March 2026. After this date, all connections using Basic Authentication will no longer function.

 

What This Means for You

If your Alteryx workflows connect to Snowflake using Basic Authentication, they will stop working once the deprecation takes effect. To avoid disruption, you must update your connections to a more secure authentication method, such as:

  • Azure AD;
  • OAuth 2.0;
  • Key Pair Authentication

Why Is This Change Happening?

Basic Authentication relies solely on a username and password, making it increasingly vulnerable to security risks. Snowflake’s shift aligns with industry standards by prioritizing more robust authentication methods, such as OAuth, which supports Multi-Factor Authentication (MFA) for enhanced protection.

 

Action Required: Update Your Alteryx Workflows

Follow these steps to ensure seemless transition:

  1. Identify Impacted Workflows: Audit your Snowflake connections and locate connections using Basic Authentication.
  2. Update connections:
    • Navigate to identified connections and assign applicable authentication method;
    • Save the connection and sync with your server DCM (if applicable).
  1. Complete Migration by March 1, 2026.
