California – Setting Up Two-Factor Authentication (2FA) for CDTFA

Updated 4 months ago

⚠️ Important Notice (Update received as of October 31, 2025)

The CDTFA recently has issues in its login process. Codes can no longer be sent to secondary logons email. Because of this, you must temporarily replace your email address with Kintsugi’s secure Virtual Mail Group email address (VMG ID).

✅ What You’ll Need

  • Access to the CDTFA Online Services Portal

  • Your CDTFA username and password

  • Kintsugi Mail’s Virtual Mail Group (VMG) ID
    ​(Go to Configuration → Kintsugi Mail → Virtual Mail Group → Group ID in your Kintsugi app)

🔐 Step-by-Step Instructions

1. Log in to CDTFA

a. Go to https://onlineservices.cdtfa.ca.gov/

b. Enter your username and password, then click Log In.


c. If prompted with Confirm Identification, click Send Authentication Email to receive a code.


d. Enter the code sent to your registered email, select Yes to “Trust This Browser,” and click Logon.

2. Go to Your Profile Settings

  • Choose Settings → Profile.

3. Update the Email Used for 2FA

CDTFA is not able to send authentication codes to secondary logins at the moment. Please replace main email with Kintsugi’s secure Virtual Mail Group email address (VMG ID).

Here’s how:

  1. Under Profile, locate your current email address.

  2. Click Edit.

  1. Replace it with the Kintsugi Virtual Mail Group (VMG) ID.

    Access the Virtual Mail Group (VMG) ID within the Kintsugi app.
    Navigate to: Configuration > Kintsugi Mail > Virtual Mail Group > Group ID

    Copy the VMG ID:

4. Verify the Change

  • A verification code will be sent to the email address you linked to Kintsugi’s Virtual Mail Group (VMG)

  • Copy the verification code that was sent to the email—the one you added or connected in the Virtual Mail Group. Then, paste it into the website or portal to verify and complete the 2FA setup.
    ​

Once verified, your account is now connected, and Kintsugi can access it as needed.​
