Snowflake has announced that multi-factor authentication (MFA) will become mandatory by November 2025, and single-factor password authentication will no longer be supported. Learn more about this change in the Snowflake blog.
This change will also affect Supermetrics users using Snowflake as their data destination.
To avoid disruptions, we strongly recommend migrating to key-pair authentication as soon as possible.
If you continue using username + password authentication, you will experience multiple authentication prompts (10+ per transfer run), making this method impractical.
What you need to do
If you currently use username + password authentication, you’ll need to switch to key-pair authentication as soon as possible to ensure uninterrupted access. Follow these instructions to configure key pair authentication in Snowflake.
Follow these steps to transition your transfers smoothly:
- Clone your existing Snowflake destinations. Go to the Storage destinations page on the Supermetrics Hub, and click the Clone destination icon for each Snowflake destination you want to transition to key-pair and set up the new destination with the new authentication method.
- Edit your current transfers. Go to the Transfers page on the Supermetrics Hub, and edit each Snowflake transfer by selecting Edit transfer under the three-dot menu. Switch the destination of the transfer to the newly created Snowflake destination.
