Zoho DataPrep: Introduces Private Key & OAuth Support for Snowflake Connections

Hello Everyone,

Passwords alone just don’t cut it anymore.

As cybersecurity threats continue to evolve, Zoho DataPrep is stepping up to protect your data—starting with how you connect to Snowflake.

In line with Snowflake’s pledge to the CISA Secure by Design initiative, single-factor authentication using only a password is being officially phased out. Starting October 2024, all new Snowflake accounts will require multi-factor authentication (MFA) by default. By November 2025, single-factor password sign-ins will no longer work.

So, what’s changing in Zoho DataPrep?  

Starting in August 2025, Zoho DataPrep will introduce private key and OAuth authentication options for Snowflake connections. No more relying on just usernames and passwords. Instead, you’ll get better control, tighter security, and full compliance with Snowflake’s latest policies.

Here's your action plan:  

Step 1: Go to the Saved Connections tab in Zoho DataPrep.

Step 2: Click the ellipsis (…) next to the connection you want to update and select Edit Connection

Step 3: You’ll see the default username/password option. Change this to either Private Key or OAuth authentication.

Step 4: Update the details and hit Update. That’s it!

FAQs:  

Q: What happens if I don’t update my connection?
Your connection will work only until November 2025. After that, if you're still using password-based login, you’ll lose access.

Q: Do I need to create a brand new connection?
Nope. Just edit your existing one using the steps above.

Don’t wait until the last minute. Upgrade your Snowflake connections in Zoho DataPrep today and stay one step ahead—because securing your data isn’t just good practice. It’s the future.
