# Collaborating on a Amazon DCV session
<a name="managing-sessions-session-collaboration"></a>

Amazon DCV users can collaborate on the same session, enabling screen and mouse sharing. Users can join authorized sessions while session owners can disconnect users from any session collaboration. To take advantage of this feature, users must join the same session identified by the same session ID.

**Note**  
When collaborating on Amazon DCV sessions, the multiple monitor function is disabled.

**Requirements**

By default, the only user that can connect to a Amazon DCV session is the owner of that session.

For users to collaborate on the same session, the active permissions applied to the session need to be updated to include the `display` parameter. For more information on editing the permissions file, see [ Configuring Amazon DCV authorization](https://docs.aws.amazon.com/dcv/latest/adminguide/security-authorization.html).

**Note**  
Administrator privileges are required to edit the permissions file.
