User groups and permissions

User groups are XenForo's primary method of assigning roles to the users of your forum. This allows you to assign permissions, titles and other customizations to users.

XenForo's group and permission system is very powerful. However, it may work differently than you're accustomed to with other software. You will find you get better results if you adapt your approaches to work with the concepts presented here.

User groups as roles

XenForo comes with four default user groups that you cannot remove, though you can rename them:

  1. Unregistered / unconfirmed
  2. Registered
  3. Administrative
  4. Moderating

The first two are the most significant initially. Unregistered / unconfirmed represents all guests and any users who have an account that is not in a confirmed/valid state. Registered represents all registered users.

All users must belong to at least one user group but can be members of many. We recommend that all users have the registered group as their primary user group -- including your moderators and administrators! When a new user registers, they will always be put in the registered group automatically.

If you're coming from a different forum software, having your admins and moderators be members of the registered group may seem awkward. However, if you consider user groups to be "roles", the concepts will begin to make sense.

Any user account on your forum is, by definition, a registered member. A user who is a moderator should also be in the moderating role (group). Similarly, if a user is an admin and a moderator, they should be in the registered, administrative and moderating roles (groups).

Taking this approach allows you to:

  • Define a baseline set of permissions for the registered group. These are the permissions that all registered users will have.
  • For each additional role, you then only need to consider the additional permissions that they will receive. (All other permissions can be left at no/inherit. See below.)

If done correctly, you will not be duplicating permission configurations across groups. If you find that two groups require nearly identical permissions, consider either merging them or using an additional group to represent the share components.

How permissions are applied

There are multiple permission sets that come together to define a user's final set of permissions. Under the Groups & permissions section, these include:

  • User group permissions: the permissions defined for each user group you have created
  • User permissions: an optional set of additional permissions to apply to specific users. This is used for things like moderator permissions. However, if you are ever going to apply the same permissions to multiple users, we recommend creating user groups.
  • Node permissions: these are override permissions for specific nodes. This will be discussed more in the next section.

Add-ons may define additional permission types. These will behave similarly to node permissions.

To determine the global permissions for a user, we collect the permissions from all the groups they're a member of and any custom user permissions. The final value for a permission is then determined by which value has the highest priority.

Permission value priority

As a user may be in many groups and have their own custom permissions, determining the final permission value is done by determining which value has the highest priority. The priority is defined as: (highest priority first)

  1. Never: this is an overriding no and the permission is not granted. It always trumps other values and should only be used in specific scenarios.
  2. Yes: the permission is granted.
  3. No: the permission is not granted.

To make this clearer, here are some examples of what permission would "win" in various scenarios:

  • No + Yes = Yes
  • No + Never = Never
  • Yes + Never = Never

For numeric permissions, the highest value from all of the groups and user permissions is used.


"Never" is a powerful feature but it can cause problems if used inappropriately. It is designed for being applied to groups that are used for user discipline, such as by removing permissions to users that have a certain number of warning points. Do not use it for the default registered group!

Node permissions

Node permissions allow you to define permissions that will only apply to a specific node. Like the global permissions, these can be applied to user groups and individual users.

Initially, these permissions are inherited from the global permission values. If you customize a permission for a particular node, that new value will now be inherited by any child nodes as well, unless they too customize the value.

Differences from global permissions

Node permissions are very similar in concept and application to the global user group and user permissions and the examples given above.

However, instead of defaulting to No, node permissions default to Inherit. If any custom permission value is set, it will be used instead of the inherited version; essentially, Inherit is the lowest priority permission value.


There is one exception to this rule. If the inherited value is Never, it cannot be overridden, even by child nodes.

Private nodes

When setting the permissions for a node, you have the option to make the node private. Enabling this will prevent all access except where explicitly granted.

This is ideal for creating staff-only forums. To do this, you would make the forum private and then set View node to Yes for the administrative and moderating user groups.

Confirming permissions are correct

To confirm that a user is receiving the permissions you expect, use the Groups & permissions > Analyze permissions system. This allows you to see the final yes/no value for each permission, along with all of the permissions that were considered leading up to that decision.

This analysis can be done for a user's global or node-specific permissions.

Other uses for groups

Setting custom permissions is probably the most significant use for user groups, but they can also be used to customize how users may appear to others.

If a user is a member of a multiple groups, the configuration of the group with the highest Display styling priority value will be used in most of the features listed here.

  1. User title override: this controls whether a user's title comes from this group or the standard user title ladder. Note that a user-specific custom title will override both.
  2. User name CSS: this can be used to apply color or other flourishes to the name of users in this group. Note that the user name styling is not used in all scenarios.
  3. User banners: if specified, a banner will be displayed below the user's name on their posts. Further configuration for this can be found in Setup > Options > User options > User banners.


In XenForo, there are two types of staff members, moderators and administrators. These are entirely distinct roles in terms of the permissions granted. Making a user an administrator does not make them a moderator; these roles need to be assigned separately.


Moderators are users that are given special privileges on your site, generally to help manage the content other users submit to the site. This includes things like deleting posts that violate rules, moving threads to more appropriate locations, and handing out warnings. The exact permissions that a moderator has can be set when the moderator is configured.

There are two types of moderators: super and forum-specific. Super moderators have permissions in all forums by default, while a forum moderator is only able to use those permissions in the specific forums they're assigned to.

In order to have access to allow of the moderator tools and functionality, a user must explicitly be made a moderator. Adding a user to the Moderating user group does not make them a moderator. They must be added via Groups & permissions > Moderators.

The moderator bar will be displayed at the top of the page for all moderators. This allows them to access the approval queue and reported items.


Administrators are users that can access and perform actions within the administrator control panel. Making someone an administrator does not inherently give them additional access to the forum.

There are two types of administrators: super and regular. Super administrators always have access to all parts of the control panel and can add/remove other administrators. Regular administrators are controlled by the specific permissions applied to them. They are unable to add/remove administrators.

Staff security

Administrators and moderators have enhanced access to your forum. If an attacker is able to gain access to one of these accounts, they may be able to delete/manipulate content or deface your site. Therefore, it is very important that you and your staff take precautions to ensure that your accounts cannot be accessed unexpectedly. Here are several tips to help avoid that:

  1. Use a unique password for your site. Most account takeovers are caused by password reuse. The best method to ensure that you don't reuse passwords is to use a password manager.
  2. Enable two-step verification. This ensures that even if an attacker gains access to your password, they will need a second authentication token to login. You can force your staff to enable two-step verification through permissions or by blocking access to the control panel until they enable it.
