$ curl -XPUT -u elastic 'localhost:9200/\_xpack/security/user/elastic/\_password' -H "Content-Type: application/json" -d '{  
"password" : “1234”  
}'  
Enter host password for user 'elastic':  
{"error":{"root\_cause":[{"type":"security\_exception","reason":"failed to authenticate user [elastic]","header":{"WWW-Authenticate":"Basic realm="security" charset="UTF-8""}}],"type":"security\_exception","reason":"failed to authenticate user [elastic]","header":{"WWW-Authenticate":"Basic realm="security" charset="UTF-8""}},"status":401}%

My license is basic but i have used 'trial type'. So i want to give different access to users by using x-pack that is installed by default elastic v6.4.0  
I think [elastic]'s default passwd is 'changeme'. but above error appeared.

1. How can I solve this issue?

2. How can I initialize x-pack on Elastic,Kibana v6.4.0?

Hi there

There's no default password for the elastic user . You can set the password of the internal users using [the setup-passwords](https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-passwords.html) utility.

You can read more [in our documentation](https://www.elastic.co/guide/en/elastic-stack-overview/current/setting-up-authentication.html)
