What is Snowflake's recommended authentication method for automated service accounts and headless ETL/ELT pipelines (e.g., Python connectors, SnowSQL scripts)?

Key Pair Authentication (RSA 2048-bit minimum key pair) — Key Pair authentication using RSA public/private keys (minimum 2048-bit) is the official Snowflake best practice for service accounts and automated pipelines because it does not require interactive password prompts or MFA challenges.

Which technology does Snowflake natively integrate with to provide Multi-Factor Authentication (MFA) across all editions without additional licensing cost?

Duo Security — Snowflake includes built-in Multi-Factor Authentication powered by Duo Security for all accounts and editions at no extra cost. Users enroll via the Duo Mobile app on their smartphone or tablet.

A data engineering team needs to rotate the RSA public key for an ingestion user without causing downtime to running ingestion pipelines. How does Snowflake support zero-downtime key rotation?

By executing ALTER USER ... SET RSA_PUBLIC_KEY_2 = ' ', switching clients to the new private key, and subsequently removing the old key — Snowflake provides two user properties (RSA_PUBLIC_KEY and RSA_PUBLIC_KEY_2). Setting RSA_PUBLIC_KEY_2 allows both keys to authenticate concurrently while clients update their credentials, after which the old key can be unset.

Authentication Methods

Overview

Snowflake supports a wide range of authentication methods to ensure secure access. Knowing the differences between MFA, SSO, Key Pair, and modern authentication policies is vital for the COF-C03 exam.

Key Concepts

Basic Authentication & MFA

Key Pair Authentication

Used primarily for programmatic access (e.g., service accounts, SnowSQL, Python scripts) rather than human users. It uses an RSA 2048-bit (or stronger) public/private key pair instead of a password.
