######################### LibreSignage User Manager ######################### The LibreSignage User Manager is available for users of the group *admin*. Other users can't access the page. This page is used for managing the users and groups of the LibreSignage instance. Editing users ------------- Users can be edited by clicking the name of a user in the list of users on the *User Manager* page. This opens a dropdown editor for editing user settings. Admins can only edit the groups of a user. Usernames are immutable and can't be changed after creation. If a username needs to be changed, the user must be deleted and recreated with a different name afterwards. New user groups can be added by writing a group name in the *Groups* input box and clicking the *Plus (+)* button. Group names can only contain the characters A-Z, a-z, 0-9, - and _. Groups can be removed by clicking the *X* symbol next to a group name in the list. Note that you must save the user data afterwards by clicking the *Save (Floppy icon)* button or the changes won't be preserved. Users can be removed by clicking the *Remove (Trash icon)* button. Creating new users ------------------ New users can be created by clicking the *New user* or *New passwordless user* buttons and specifying a name for the new user in the popup dialog. The maximum length of a username is set in the LibreSignage instance config and can be changed only by server admins. The maximum length is 64 characters by default. When a new user is created by clicking the *New user* button, they are given a automatically generated password. The initial password is visible to the admin user in the *Password* box in the user editor dropdown until the page is reloaded. The password is not visible or even known by the server on subsequent reloads of the page. The *New passwordless user* button creates a user without a password, meaning you can login as the new user without supplying any password. This is handy if you need to create users for many individual people who then set the passwords by themselves. **For increased security it's recommended to create normal users instead.** Passwordless users can also be used for public facing display clients where authentication is not needed. LibreSignage includes a system for automatically logging in a display client as a passwordless user. Please see `Display Setup `_ for more info.
