Hello YU, and welcome to the UTM Community! 
 I like for people to post in their native language if they are not comfortable in English, but it's polite to supply the result of Google Translate. I like that better than just posting the result from Google Translate. 
 I prefer to change only the password for the admin account if one already knows the root password and can access the console with a keyboard and monitor. If I want to change it to Be1j1ng! 
 cc passwd Be1j1ng! 
 Of course, if you can't get in as root, you will need to follow the KnowledgeBase article suggested by Bruno. 
 Cheers - Bob
