 !!! You should be aware that the SSO can only be reached through the actual domain name (i.e. `https://the.domain.tld/yunohost/sso`), and NOT by just using the IP of the server (i.e. `https://11.22.33.44/yunohost/sso`), contrarily to the webadmin ! This is a bit confusing but is necessary for technical reason. If you are in a situation where you need to access the SSO without having your DNS properly configured for some reason, you might consider tweaking your `/etc/hosts` as described in [this page](/dns_local_network).
 
+## Creating new users
+
+Only the administrator can create new users. From the webadmin, open the `Users` menu and click on the `+ New user` main button. Fill in all the whole form.
+
+Users are created with an associated email address (and XMPP account) with the format `username@domain.tld`. Additional email aliases and email forwards can later be added by the admin and the user.
+
+The password should be at least 8 characters - though it is good practice to use longer password (i.e. a passphrase) and/or to use various kind of characters (uppercase, lowercase, digits and special characters).
+
+Finalize the user creation by clicking on the `Save` button.
