How to add the same user to multiple domains?

First of all, you will need to have access to user management of multiple domains yourself.

If that's the case, you can just go to a first domain (see "How to add new users to a specific domain?") and add the user by inserting their emailaddress. From there, you've got two options:

  1. repeat the steps for each domain. We will recognize that the user is already in our database. This means a user can use the same password to access all joined domains;
  2. or, after adding a user to a first domain, edit the user. You will then see a complete list of all domains you have permissions to as well. From there, you only have to check some checkboxes.
