  • To change a users password you need to have sudo privileges yourself.
    sudo passwd username will change the password for the 'username' you want to change.

  • Thanks. What I really want is - I hired a developer and gave him an access on our server, after his job was done, I realized that he still has an access onto the server even though the root password was changed right after he finished working. My guess is that he has an account with root privileges, and would like to change at least his password after finding the account somehow...The best case scenario for me is to find out how many user account has admin privileges, and then which credentials has to be changed.
    Would you happen to know how to say look up ALL users, and then from there I can change password of usernames that i don't recognize.

  • To list users you can use this terminal command (when you are logged in...)

    cut -d: -f1 /etc/passwd

    That being said... you are going to see a great many usernames you do not recognize... and those are system users that are needed to perform certain tasks - so you do not want to delete them.

    You can check your users against these:

    root
    daemon
    bin
    sys
    sync
    games
    man
    lp
    mail
    news
    uucp
    proxy
    www-data
    backup
    list
    irc
    gnats
    nobody
    libuuid
    syslog
    messagebus
    landscape
    sshd
    colord
    sheriffderek
    mysql

    Where 'root' and 'sheriffderek' - are the only usernames I was previously aware of... so - your additional users should be in addition to these.

    Also, you should just delete the users you don't want instead of just changing the passwords. It's just as easy to create new ones.

    This is what I found when I googled your question:

    ps: can you change your question title to - 'How may I reset a user's password: Ubuntu 14.04' - or something that is a little more clear, for others. : )
