If you are the administrator of any Paratext project, you may register for someone who has difficulty accessing the internet or who does not have an e-mail address. Users registered in this way will be able to participate in projects and use resources, but will not be able to register projects of their own until they sign up for themselves.
Go to registry.paratext.org and click on the Users tab. At the top of the page you will see a button to add a new user:
Fill out the form and you will receive the registration code after a delay if approval is necessary.
