Snowflake to Block Single Factor Authentication in 11 Months

Company details three stages to remove single factor logins by end of 2025.


Snowflake has announced that it will block sign-ins using single-factor authentication with passwords by November 2025.

In an announcement, the company said this will be enabled in three stages:

By April 2025, all human users in accounts without a custom authentication policy will be required to enroll in MFA upon their next password-based sign-in to Snowflake.

By August 2025, even if the customer has a custom authentication policy already defined, all ‘human users’ - users who are human and normally use an interactive login to sign in to Snowflake - will be required to use MFA when signing in with passwords.

By November 2025, the LEGACY_SERVICE will be deprecated, and all LEGACY_SERVICE users will be migrated to SERVICE users. This will conclude the process of blocking sign-in to Snowflake using single-factor authentication with passwords for all users (human or service).

The announcement follows the addition of mandatory MFA earlier this year.
