**Question:**  
Is it possible for anonymous (no-login) users to join meetings hosted on another Zoom account using only an unlisted JWT-based Android Meeting SDK app, or is OAuth authentication (or a WebSDK workaround) required?

## Environment

- **Meeting SDK:** Zoom Android SDK
- **Version:** 6.4.5.29521

## Setup

1. **Zoom Account One**

2. **Android Client App**

* * *

## Current Behavior

- **Success:** Joining meetings hosted by **Account One ( Mine )**
- **Failure:** Joining meetings owned by **any other Zoom account** always fails with error code : 63

* * *

## Question

1. Can truly anonymous users (no login/OAuth) join external-account meetings via an **unlisted JWT Meeting SDK**?
2. If not, must I switch to an **OAuth-based SDK app** or embed the **WebSDK** (e.g., in a WebView) to support guest participants?

@Riddhi the application must be published and approved for cross account join.

Do ensure that you are using the production credentials after the application is approved.
