# Rex permissions

> Control what Rex can read and change in each connected tool, and who can use Rex.

## Where permissions live

**Settings → Connections** shows each connection's status and the Rex permissions for it. People whose role administers the company or the Location control which tools and data Rex can use there. Labels in your account may vary slightly; the concepts below apply.

## Permission levels

| Permission | Settings | Meaning |
| - | - | - |
| Reading | **Allow** or **Off** | Whether Rex can read data from this tool |
| Changes | **Allow**, **Ask**, or **Off** | Whether Rex can make changes, must ask first, or can't change anything |

These settings work with each person's mode. In **Ask** mode, Rex waits for confirmation before any change. In **Apply** mode, Rex can make internal changes these settings allow. External actions, such as sending email, always need the current user's confirmation. See [Act with Rex](/rex/act).

## What permissions don't do

* They don't give anyone an Admin role. Rex works within the current user's access; see [Members and roles](/features/members-and-roles).
* They don't unlock plan features. Changes to XBuild records still respect what your plan includes; see [Plan comparison](/plans-billing/plan-comparison).
* They don't override a read-only conversation or company policy.

## Who can use Rex

Rex needs all of the following:

* Rex enabled for the selected [Location](/features/locations)
* the feature included in your plan
* an Admin or Standard role; Limited members don't get Rex

## Choosing settings

* Start with reading allowed and changes set to **Ask** for tools your team is still learning.
* Use **Off** for tools Rex shouldn't touch.
* Revisit settings when you add a connector; see the [connectors overview](/connectors/overview). [Google Drive](/connectors/google-drive) is a personal connection each person sets up for themselves.

## Troubleshooting

* **Rex says it can't reach a tool.** Check the connection status and the read permission in **Settings → Connections**.
* **Rex keeps asking before changes.** The change permission may be **Ask**, the user may be in Ask mode, or company policy may require you to confirm that action yourself.
* **A teammate can't see Rex.** Check their selected Location and role.
* **Rex isn't available for anyone.** Contact XBuild Support to confirm your account's Rex setup.
