How to Fix: “The Auth mode for the messaging channel should be unAuth” in Salesforce

Are you in the middle of migrating your Salesforce Messaging for In-App and Web (MIAW) setup from V1 to V2? It’s usually a seamless process—until you hit a roadblock.

One of the most common errors admins encounter during this migration is the cryptic exception:

“The Auth mode for the messaging channel should be unAuth”

If this error has stopped your deployment in its tracks, don’t worry. This is a known configuration conflict related to User Verification settings during the transition phase.

In this post, we’ll break down why this happens and the exact steps to resolve it so you can complete your V2 upgrade.

The Problem: Migration Blocked by Auth Settings

This error typically occurs when you attempt to click the “Switch to V2” button within your Embedded Service Deployment.

Salesforce attempts to migrate your current configurations to the new V2 architecture. However, if your existing Messaging Channel has “Add User Verification” enabled, the migration tool flags a conflict. The migration process requires the channel to be in an “Unauthenticated” state (unAuth) to successfully bridge the gap between the legacy V1 and the new V2 framework.

The Solution: Disable User Verification Before Switching

To resolve this, you need to temporarily disable the verification security setting on the specific Messaging Channel you are trying to upgrade.

Follow these steps to fix the exception:

Step 1: Identify the Messaging Channel

First, note which Embedded Service Deployment is throwing the error and identify the Messaging Channel linked to it.

Step 2: Navigate to Messaging Settings

  1. Go to Setup.
  2. In the Quick Find box, type Messaging Settings.
  3. Select Messaging Settings.

Step 3: Modify the Channel Configuration

  1. Locate the Messaging Channel connected to your deployment.
  2. Click the dropdown arrow next to the channel name and select Edit.
  3. Scroll to the security section.
  4. Uncheck the box labeled “Add User Verification”.
  5. Click Save.

Step 4: Retry the V2 Migration

Now that the channel is in an “unAuth” state:

  1. Navigate back to Embedded Service Deployments.
  2. Locate your deployment.
  3. Click the Switch to V2 button again.

The error should now be cleared, allowing the migration wizard to proceed.

Note: Once you have successfully switched to V2, you can review your new deployment settings and re-enable User Verification if your use case requires authenticated messaging.

Summary

Migrating to the latest Salesforce features is vital for keeping your org healthy, but configuration mismatches can be frustrating.

To recap:

  • The Error: “The Auth mode for the messaging channel should be unAuth”
  • The Cause: User Verification is enabled during the V1 to V2 switch.
  • The Fix: Disable “Add User Verification” in Messaging Settings -> Switch to V2 -> Re-enable if needed.
