[[security-api-users]]
=== User Management APIs

The `user` API enables you to create, read, update, and delete users from the
`native` realm. These users are commonly referred to as *native users*.
To use this API, you must have at least the `manage_security` cluster privilege.

[[security-api-put-user]]
To add a user, submit a PUT or POST request to the `/_xpack/security/user/<username>`
endpoint.

[[username-validation]]
NOTE: A username must be at least 1 character and no longer than 30 characters.
      The first character must be a letter (`a-z` or `A-Z`) or an underscore (`_`).
      Subsequent characters can be letters, underscores (`_`), digits (`0-9`),
      or any of the following symbols `@`, `-`, `.` or `$`

.User Fields
[cols="4,^2,10"]
|=======================
| Name        | Required  | Description
| `password`  | yes       | The user's password. Passwords must be at least 6
                            characters long.
| `roles`     | yes       | A set of roles the user has. The roles determine
                            the user's access permissions
| `full_name` | no        | The full name of the user
| `email`     | no        | The email of the user
| `metadata`  | no        | Arbitrary metadata that you want to associate with
                            the user.
|=======================

A successful call returns a JSON structure that shows whether the user has been
created or updated.

[source,js]
--------------------------------------------------
{
  "user": {
    "created" : true <1>
  }
}
--------------------------------------------------
// TESTRESPONSE
<1> When an existing user is updated, `created` is set to false.

NOTE: You also use the PUT user API to update users. When updating a user, you
      can update everything but its `username` and `password`. To change a user's
      password, use the  <<security-api-reset-user-password, reset password API>>.

Once you add a user through the Users API, requests from that user can be
authenticated.
