# Admin settings

> How to add and remove project administrators on Project Management → Admin Settings, and what the errors mean.

**Where:** sidebar **Project Management** → **Admin Settings** tab

Whoever creates a project becomes its **owner**, and the owner can add other users as **administrators**. An administrator works with the project's workflows, profiles, and analyses at the same scope as the owner.

## Adding an administrator

| Input | Rule                                                                                        |
| ----- | ------------------------------------------------------------------------------------------- |
| Email | The email of a user **already registered** with Omni. An unregistered email cannot be added |
| Name  | Letters and digits only. Must be unique within the project                                  |

Selecting **+ Add** puts the user in the **Admin List** immediately; there is no approval step. The list has three columns — Email, Name, and an action column with **Delete** — and the heading shows the current count. The user sees this project in their project list from their next sign-in.

## Removing an administrator

Use the **Delete** button on the row. The owner cannot be removed. A removed user loses access to the project, but the workflows and profiles they created stay exactly as they are.
