The Change Password API enables you to submit a request to change the password
of a user. Every user can change their own password and users with the
manage_security privilege can change passwords of other users.
To change the password of the logged in user, submit a POST request to the
_xpack/security/user/_password endpoint:
POST _xpack/security/user/elastic/_password
{
"password": "changeme"
}A successful call returns an empty JSON structure.
