`PUT /_xpack/security/user/<username>`
==== Description
When updating a user, you can update everything but its `username` and `password`.
To change a user's password, use the
<<security-api-change-password, change password API>>.

{stack-ov}/realms.html[Realms] and <<configuring-native-realm>>.

The following example creates a user `jacknich`:
[source,js]
--------------------------------------------------
POST /_xpack/security/user/jacknich
{
"password" : "j@rV1s",
"roles" : [ "admin", "other_role1" ],
"full_name" : "Jack Nicholson",
"email" : "jacknich@example.com",
"metadata" : {

// CONSOLE
A successful call returns a JSON structure that shows whether the user has been
created or updated.
[source,js]
--------------------------------------------------
{
"created": true <1>
}
--------------------------------------------------
// TESTRESPONSE
<1> When an existing user is updated, `created` is set to false.

[source,shell]
--------------------------------------------------
curl -u jacknich:j@rV1s http://localhost:9200/_cluster/health
