# Upgrade a guest user to an admin role

## Why this feature is needed

Organizations sometimes need external users to do more than participate in missions. In some cases, a trusted external partner, consultant, or collaborator needs administrative access to help manage the platform.

By default, guest users are treated as external users because their email address does not match your company domain. To allow one of these users to become an [Admin](https://www.acceptmission.com/fr/encyclopedia/admin/), their domain must first be added to the trusted domain list in the platform security settings.

## What this feature is

A guest user is an external user who does not share the same email domain as your organization. Guest users can be invited to participate in missions, selections, and other collaboration activities, but they are not automatically trusted for administrative access.

To upgrade a guest user to an [Admin](https://www.acceptmission.com/fr/encyclopedia/admin/) role, you must first trust the user’s email domain in Application Settings. Once the external domain is listed as trusted, that user can be assigned an [Admin](https://www.acceptmission.com/fr/encyclopedia/admin/) role according to your organization’s access rules.

## Access level

[Admin](https://www.acceptmission.com/fr/encyclopedia/admin/)

You need [Admin](https://www.acceptmission.com/fr/encyclopedia/admin/) permissions to manage security settings and assign administrative access to another user.

## Navigation path

Navigation path: Innovation Studio → Settings → Security

## How to use this feature

External users are identified by their email domain. If a user belongs to another company, their domain is treated as external. This means the user remains a guest until their domain is explicitly trusted.

Before assigning the [Admin](https://www.acceptmission.com/fr/encyclopedia/admin/) role, confirm that the user should have elevated access and that their domain is approved by your organization.

### Step by step instructions

1. Open **Innovation Studio**.
2. Go to **Settings**.
3. Select **Organizational setup**.
4. Select **Security**.
5. Locate the list of trusted domains.
6. Review your current company domain, for example **example.com**.
7. Add the external user’s domain to the trusted domain list, for example **xyz.com**.
8. Save the security settings.
9. Go to the relevant user management area and assign the user the **[Admin](https://www.acceptmission.com/fr/encyclopedia/admin/)** role.

## Configuration and adjustments

Trusted domains are managed in **Innovation Studio → Settings → Security**. Any domain added here is treated as trusted by the platform for access control purposes.

Only add external domains that are approved by your organization. Expanding the trusted domain list affects who can potentially receive elevated access, so this should be reviewed carefully as part of your governance process.

## Practical example – Innovationlands

Innovationlands works with an external innovation consultancy to support a seasonal attraction program. One consultant has already joined several [Mission](https://www.acceptmission.com/fr/encyclopedia/mission/) selections as a guest user using the email domain **partner-innovation.com**.

The Innovationlands [Admin](https://www.acceptmission.com/fr/encyclopedia/admin/) decides that this consultant now needs broader platform access to help manage evaluation settings and oversee cross-park collaboration. To allow this, the [Admin](https://www.acceptmission.com/fr/encyclopedia/admin/) opens **Settings → Security** and adds **partner-innovation.com** to the trusted domain list.

After saving the change, the consultant can be assigned an [Admin](https://www.acceptmission.com/fr/encyclopedia/admin/) role. This allows Innovationlands to extend administrative responsibility to a trusted external partner while keeping access controlled through the domain trust configuration.
