OAuth (Open Authorization) is an industry-standard protocol that enables third-party applications to obtain limited access to Snowflake resources on behalf of users.
In Snowflake, OAuth integration supports two primary flows: External OAuth and Snowflake OAuth. External OAuth allows organizations to use their existing identity providers such as Okta, Azure AD, or custom OAuth servers to authenticate users. Snowflake OAuth is a built-in option where Snowflake acts as both the authorization and resource server.
To configure OAuth integration, administrators create a security integration object using the CREATE SECURITY INTEGRATION command. This integration defines the OAuth provider settings, including client credentials, token endpoints, and scope mappings. The integration maps OAuth tokens to Snowflake roles, controlling what resources authenticated users can access.
Key benefits of OAuth integration include enhanced security through token-based authentication, elimination of password management overhead, and seamless single sign-on (SSO) experiences for users. Tokens have limited lifespans and can be revoked, reducing the risk associated with compromised credentials.
For programmatic access, applications receive access tokens after successful authentication with the identity provider. These tokens are then presented to Snowflake when establishing connections. Snowflake validates the token against the configured security integration and grants access based on the mapped roles.
Administrators can monitor OAuth usage through the LOGIN_HISTORY view, which tracks authentication attempts and methods. They can also configure token validity periods and refresh token policies to balance security with user convenience.
OAuth integration is particularly valuable for organizations with existing identity management infrastructure, enabling centralized access control and audit capabilities while maintaining Snowflakes robust security model. It supports modern application architectures and facilitates secure API-based interactions with Snowflake resources.
OAuth Integration in Snowflake: A Complete Guide
Why OAuth Integration is Important
OAuth integration is a critical security feature in Snowflake that enables secure, token-based authentication for client applications. It eliminates the need for storing and transmitting user passwords, significantly reducing security risks. Organizations benefit from centralized identity management, single sign-on capabilities, and enhanced compliance with security standards.
What is OAuth Integration?
OAuth (Open Authorization) is an industry-standard protocol that allows third-party applications to access Snowflake resources on behalf of users through secure access tokens. In Snowflake, OAuth integration creates a trust relationship between Snowflake and an external OAuth 2.0 authorization server (Identity Provider).
Snowflake supports two types of OAuth: • Snowflake OAuth - Uses Snowflake's built-in OAuth service • External OAuth - Integrates with external identity providers like Okta, Azure AD, PingFederate, or custom OAuth servers
How OAuth Integration Works
Step 1: Security Integration Creation An administrator creates a security integration object in Snowflake using the CREATE SECURITY INTEGRATION command, specifying OAuth-related parameters.
Step 2: Client Registration The client application is registered with the authorization server and receives client credentials.
Step 3: Token Request When a user attempts to connect, the client application requests an access token from the authorization server.
Step 4: Token Validation Snowflake validates the access token against the configured security integration.
Step 5: Session Creation Upon successful validation, Snowflake creates a session for the authenticated user.
Key Configuration Parameters
• TYPE = EXTERNAL_OAUTH or OAUTH (for Snowflake OAuth) • EXTERNAL_OAUTH_TYPE - Specifies the IdP type (OKTA, AZURE, PING_FEDERATE, CUSTOM) • EXTERNAL_OAUTH_ISSUER - The URL of the token issuer • EXTERNAL_OAUTH_TOKEN_USER_MAPPING_CLAIM - Maps token claims to Snowflake users • EXTERNAL_OAUTH_SNOWFLAKE_USER_MAPPING_ATTRIBUTE - The Snowflake user attribute for mapping • EXTERNAL_OAUTH_AUDIENCE_LIST - Expected audience values in the token
Exam Tips: Answering Questions on OAuth Integration
1. Understand the Difference Between OAuth Types Know that Snowflake OAuth is simpler to set up and managed by Snowflake, while External OAuth provides more flexibility and integrates with existing enterprise identity infrastructure.
2. Remember Key Commands • CREATE SECURITY INTEGRATION is used to configure OAuth • DESCRIBE INTEGRATION shows configuration details • ALTER INTEGRATION modifies settings
3. Focus on Use Cases OAuth is commonly tested in scenarios involving: • Third-party BI tool connections • Custom application authentication • Enterprise SSO implementations
4. Token Handling Knowledge Understand that access tokens are short-lived and refresh tokens can be used to obtain new access tokens based on the integration configuration.
5. Role and Privilege Requirements Remember that ACCOUNTADMIN or a role with CREATE INTEGRATION privilege is required to create security integrations.
6. Common Exam Scenarios • Questions about which OAuth type to use for specific IdPs • Configuration parameter purposes • Troubleshooting authentication failures • Security benefits compared to password-based authentication
7. Key Distinctions to Remember • OAuth is for programmatic access, not console login • SAML is used for web-based SSO to the Snowflake UI • OAuth tokens contain claims that map to Snowflake users
