Restrict name and email changes

Prevent users from changing their name

By default, any user can change their name. You can instead prevent users from changing their name. Organization administrators can always change anyone's name.

This setting is especially useful if user names are managed via an external source, and synced into Zulip via the Zulip API or another method.

Prevent all email changes

By default, any user can change their email address. However, you can instead prevent all email changes. This is especially useful for organizations that are using LDAP or a another single sign-on solution to manage user emails.
