Ready to supercharge your data transformations? Let's dive into connecting dbt™ to Snowflake. We'll cover three rock-solid methods: username/password, OAuth, and key pair authentication in this guide. Buckle up!

1. Username and Password: The Classic Approach

Simple and straightforward, but watch out for security risks.

Here's how to set it up in your profiles.yml:

‍

Working with YAML file and storing username and passwords in local machines is not recommended and poses significant security risks. So, in Paradime we make the process as easy as filling up a form and we generate and store the profiles.yaml securely in the cloud. See how to setup Snowflake using Username-Password in Paradime.

2. OAuth: Secure and User-Friendly

OAuth is the way to go for enhanced security.

2.1 First, set up an OAuth app in Snowflake:

‍

While creating the OAuth app in Snowflake, pay attention to the redirect_uri and the token_ validity parameters above. Redirect URI depends on the provider you are using. For example, in Paradime, you can find the redirect URIs at in our Configure Snowflake OAuth section of the help docs.

Get the client ID and secret in the previous step as follows:

2.2 Now, update your profiles.yml:

‍

In Paradime, this process is significantly faster. Once an OAuth app is created, an admin on Paradime can create the connection and every additional user just needs to authenticate from Paradime on their Snowflake. The biggest benefit of this approach is that users can use Paradime and SSO + MFA on their Snowflake all together. See how to setup Snowflake using OAuth with Paradime.

3. Key Pair Authentication: For the Security Obsessed

3.1. Generate the private key:

This command does two things:
- Generates a 2048-bit RSA key
- Converts it to PKCS8 format, which Snowflake requires

‍

3.2. Extract the public key:

This extracts the public key from your private key file.

‍

3.3. Format the public key for Snowflake:

This command formats the public key as a single line with '\n' for newlines, and copies it to your clipboard.

‍

3.4. Add the public key to your Snowflake user:

‍

3.5. Use the private key in your dbt™ profile:

‍

Key points to remember:

- Keep your private key (rsa_key.p8) secure and never share it
- The public key (rsa_key.pub) is safe to share with Snowflake
- Use a strong passphrase if you choose to encrypt the private key
- Store the private key path securely, preferably as an environment variable

Remember to handle these keys with care. The private key grants access to your Snowflake account, so treat it like a password.

Keeping private key stored in local laptops defeats the purpose of enhanced security. On Paradime, we make this process much more secure by generating the profiles.yaml and keeping it away from user access. See how to setup Snowflake and Key-Pair authentication on Paradime.

Pro Tips:

1. Always use environment variables for sensitive info.
2. Rotate credentials regularly.
3. Use the least privileged role necessary for your dbt™ tasks.
4. Test your connection with `dbt debug` before running models.

Security considerations for each of the methods:

Let's break down the security considerations for each connection method as follows:

Username/Password

• Passwords can be compromised if not properly secured

• Risk of exposure in plain text configurations

• Requires frequent password rotation

• Vulnerable to brute force attacks

• Not suitable for automated systems or CI/CD pipelines

OAuth

• More secure than username/password

• Supports token-based authentication

• Allows for fine-grained access control

• Tokens can be easily revoked if compromised

• Reduces the risk of credential sharing

• Integrates well with SSO and MFA systems

Key-Pair Authentication

• Highly secure, uses asymmetric cryptography

• Private key never transmitted over the network

• Immune to password-based attacks

• Ideal for automated systems and CI/CD pipelines

• Key rotation can be less frequent than password changes

• Requires careful management of private keys

Each connection method has its strengths and potential vulnerabilities, so choose the one that best aligns with your security requirements and operational needs.
