# Restrict name and email changes

|
## Restrict name changes
|
|
|
|
By default, any user can [change their name](/help/change-your-name).
|
|
You can instead prevent users from changing their name. This setting is
|
|
especially useful if user names are managed via an external source, and
|
|
synced into Zulip via the [Zulip API](/api/), [LDAP][ldap-sync-data] or
|
|
another method.
|
|
|
|
!!! tip ""
|
|
|
|
Organization administrators can always [change anyone's
|
|
name](/help/change-a-users-name).
|
|
|
|
{start_tabs}
|
|
|
|
{settings_tab|organization-permissions}
|
|
|
|
1. Under **User identity**, select **Prevent users from changing their
|
|
name**.
|
|
|
|
{!save-changes.md!}
|
|
|
|
{end_tabs}
|
|
|
|
## Restrict email changes
|
|
|
|
By default, any user can [change their email address][change-email].
|
|
However, you can instead prevent users from changing their email
|
|
address. This setting is especially useful for organizations that
|
|
are using [LDAP][ldap-sync-data] or another single sign-on solution
|
|
to manage user emails.
|
|
|
|
!!! tip ""
|
|
|
|
Organization administrators can always change their own email
|
|
address.
|
|
|
|
{start_tabs}
|
|
|
|
{settings_tab|organization-permissions}
|
|
|
|
1. Under **User identity**, select **Prevent users from changing their
|
|
email address**.
|
|
|
|
{!save-changes.md!}
|
|
|
|
{end_tabs}
|
|
|
|
## Require unique names
|
|
|
|
You can require users to choose unique names when joining your organization, or
|
|
changing their name. This helps prevent accidental creation of duplicate
|
|
accounts, and makes it harder to impersonate other users.
|
|
|
|
When you turn on this setting, users who already have non-unique names are not
|
|
required to change their name.
