1. Open the Cerby mobile app.
2. Log in to your Cerby workspace.
3. Activate the **Collections** tab located at the top on iOS or tap the **Collections** button located at the bottom navigation bar on Android. The **Collections** screen is displayed.
4. Tap the corresponding collection card. The collection details screen is displayed.
5. Tap the right arrow icon from the **Members** list within the **Sharing** section. The **View members** screen is displayed.**NOTE:** To update guest users’ role access from external parties, tap the right arrow from the **Guest users** list.
6. Select the corresponding member from the list. A menu is displayed at the bottom.
7. Tap the **Update role** button from the menu. The list of roles is displayed.
8. Select the user’s new role in the collection:

   * **Owner:** Users can share access and manage the collection configuration.
   * **Collaborator:** Users can only log in to the accounts, view the secrets, and download the secret attachments.

   **NOTE:** When you select a member with the **Login-only** role, you can only select the **Collaborator** role for them.
9. Tap the **Save** button.

Now you are done.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.cerby.com/cerby-mobile-app/collections/managing-your-collections/update-a-user-s-role-on-a-collection.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
