Managing Users

How to add or manage user accounts.

  4 minute read

User accounts can be added to the TrueNAS system to allow flexibility for user permissions to access shared data. Note that only the root user account can be used to log in to the TrueNAS web interface. A common practice is to create users and assign them to groups. This allows for efficient permissions tuning for large numbers of users.

If the network uses a directory service, import the existing account information using the instructions in Directory Services. When using Active Directory, Windows user passwords must be set from within Windows.

To see user accounts, go to Accounts > Users.

TrueNAS hides all built-in users by default. To see all built-in users, click and SHOW.

Creating User Accounts

To create a new user, go to Accounts > Users and click ADD.

Account options are subdivided into groups of similar options.


Enter the Full Name of the user. A simplified Username is suggested from the Full Name, but can be overriden with your own choice.

An Email address can be associated with an user account.

Set and confirm a password for the user.

User ID and Groups

Next, a user ID must be set. TrueNAS automatically suggests the user ID, starting at 1000. This suggestion can be changed if desired. It is recommended to use an ID of 1000 or more for non-builtin users.

By default, TrueNAS creates a new primary group with the same name as the user. To add the user to an existing primary group, unset New Primary Group and select an existing group from the Primary Group drop-down. The user can be added to additional groups using the Auxillary Groups drop-down.

Directories and Permissions

When creating a user, a home directory path of /nonexistent is set. This does not create a home directory for the user. To set a home directory for the user, select a path using the file browser. If the directory exists and matches the username, it is set as the user home directory. When the path does not end with a subdirectory matching the username, a new subdirectory is created. The full path to the user’s home directory is shown here when editing a user.

Directly under the file browser, the home directory permissions can be set. TrueNAS default user accounts cannot have their permissions changed.


A public SSH key can be assigned to a user for key based authentication. Just paste the public key into the SSH Public Key field. If you are using an SSH public key, it is always a good idea to keep a backup of the key. Click DOWNLOAD SSH PUBLIC KEY to download the pasted key as a .txt file.

If Disable Password is Yes, it disables the Password field and removes the password from the account. The Lock User and Permit Sudo options are also removed. The account is then restricted from password-based logins for services. For example, disabling the password prevents using account credentials to log in to an SMB share or open an SSH session on the system. By default, Disable Password is set to No.

A specific shell can be set for the user from the Shell drop-down:

cshC shell for UNIX system interactions.
shBourne shell
tcshEnhanced C shell that includes editing and name completion.
bashBourne Again shell for the GNU operating system.
ksh93Korn shell that incorporates features from both csh and sh.
mkshMirBSD Korn Shell
rbashRestricted bash
rzshRestricted zsh
scponlyscponly restricts the user’s SSH usage to only the scp and sftp commands.
zshZ shell
git-shellrestricted git shell
nologinUse when creating a system account or to create a user account that can authenticate with shares but which cannot log in to the TrueNAS system using ssh.

Setting Lock User disables all password-based functionality for this account until the option is unset.

Permit Sudo allows this account to act as the system administrator using the sudo command. It is recommended to leave this option unset.

When the user account is going to be using a Windows 8 or newer client to access data stored on TrueNAS, set Microsoft Account. This enables additional authentication methods available from those operating systems.

By default, Samba Authentication is enabled. This allows using the account credentials to access data shared with SMB.
