Introduction<\/h2>\n

Creating user and managing user password is one of the basic tasks of the Linux system administrator. That’s why the chpasswd command was born.<\/p>\n

chpasswd command is used to change the password equivalent to passwd command. But chpasswd command allows changing passwords of multiple users easily.<\/p>\n

This article will show you how to use the chpasswd command in Linux as we go through below.<\/p>\n

The syntax of chpasswd command<\/h2>\n
$ sudo chpasswd<\/pre>\n
user1:password<\/p>\n
user2:password<\/p>\n
user3:password<\/p>\n
Press Enter to go to the next user. Once done, press Ctrl+d to exit and the new password will be saved.<\/p>\n
For example:<\/p>\n
<\/p>\n
Or you can create a password file with the cat command:<\/p>\n
$ cat > file.txt<\/pre>\n
For example:<\/p>\n
<\/p>\n
Press Ctrl+ D to exit.<\/p>\n
Then send this file to chpasswd command:<\/p>\n
$ sudo chpasswd < pass.txt<\/pre>\n
Options<\/h2>\n
    \n
  1. -e<\/strong> Use encrypted password<\/li>\n<\/ol>\n
    This tells chpasswd that your password is encrypted so chpasswd won’t re-encrypt it.<\/p>\n
      \n
    1. -m , -md5 <\/strong>Use MD5 hash encryption<\/li>\n
    2. -c<\/strong> Choose 1 encryption method<\/li>\n<\/ol>\n
      For example, I want to choose DES as the encryption method for my password:<\/p>\n
      $ sudo chpasswd -c DES<\/pre>\n
        \n
      1. -h, -help <\/strong>Ask for help information from the command<\/li>\n<\/ol>\n
        Output:<\/p>\n
