# Custom profile fields
{!admin-only.md!}
By default, user profiles show their name, email, date they joined, and when
they were last active. You can also add custom profile fields like country
of residence, birthday, manager, Twitter handle, and more.
Custom profile fields are always optional, and do not appear in users'
profiles until they fill them out.
Zulip supports synchronizing custom profile fields from an external
user database such as LDAP or SAML. See the [authentication
methods][authentication-production] documentation for details.

## Display custom fields on user card
Organizations may find it useful to display additional fields on the
user card, such as pronouns, GitHub username, job title, team, etc.
All field types other than "Long text" or "Person" have a checkbox option
that controls whether to display a custom field on the user card.
There's a limit to the number of custom profile fields that can be displayed
at a time. If the maximum number of fields is already selected, all unselected
checkboxes will be disabled.

icon for the profile field you want to edit.

You can also choose which custom profile fields will be displayed by toggling
