# Regions

A sub-user can work in **Indore**, **Mumbai** or both. In each region it has its own key pair, and it can only be given buckets in its regions. An Indore key does not work on the Mumbai endpoint, and the other way round.

To change a sub-user's regions, select **Manage Regions** in its row menu (⋮) in the sub-user list, or **Manage** in the **Region** card on its page.

## Add a region

#### Choose the region

In the **Manage Regions** dialog, pick a region under **Add a region** and select **+**.

#### Save the new keys

A credentials file with the new region's access key and secret key downloads automatically. Save it — the secret key cannot be shown again.

Then [assign buckets](/sub-users/assign-a-bucket) in the new region. If the sub-user has not accepted its [invitation](/sub-users/invitations) yet, the new region stays suspended too until it does.

## Remove a region

Select the bin icon next to the region, then **Remove Region** to confirm.

> **Warning**
>
> Removing a region deletes the sub-user's keys there and removes all its bucket access in that region. This cannot be undone.

You cannot remove a sub-user's last region. To remove all its access, [delete the sub-user](/sub-users/delete-a-sub-user) instead.
