Send Invitation Email
Users and groups can only be managed by an administrator.
An administrator can send an invitation email to users with their login information. This is typically used when adding new users to inform them of their access to the RegistryUI website and the Docker Registry.
The invitation can be sent when adding a new user by selecting the "Send Invite" check box or on the Registry > Users & Groups page by using the 
icon.
The following is an example of the invitation email.
When logging on for the first time, the user will have to change his/her password.
