In the Administration panel, you can click on the Create user button, and you'll be presented with the following dialog:

<img src={require('./img/create-new-user-dialog.png').default} width="90%" title='New User Registration Dialog' />

You can then set an initial password. If you'd like, you can use an easy password like password, and keep the setting Require user to change password on first login active. This will prompt the user to change their password on first login, to a password that they choose.
