For changing all users cpanel logins the next time they login go to
\nMain >> Account Functions >> Force Password Change<\/strong> in WHM and then Select All<\/strong>,
\nthen Submit<\/strong><\/p>\n

From techtrunch.com<\/a><\/p>\n

There is a cPanel script [chpass] to reset each user\u2019s password. Its syntax is as follows<\/p>\n


\n\/scripts\/chpass username password
\n<\/code><\/p>\n

After running the script always run the following script<\/p>\n


\n\/scripts\/ftpupdate
\n<\/code><\/p>\n

Using the above cPanel script I have created my own script to change all users password in one shot.<\/p>\n


\n#\/bin\/bash<\/p>\n

cat \/etc\/trueuserdomains | sort -t\" \" -k2 > LIST.txt
\nexec 7<> LIST.txt
\nfor i in `cat \/etc\/trueuserdomains | awk '{ print $2 }' | sort`; do
\nread < &7\nDAT=$(date +%S%H%M%S)\nNAM=`echo $i | awk '{ print substr($1,3) }'`\n\/scripts\/chpass $i \"#\"$NAM$DAT\necho $REPLY \"#\"$NAM$DAT >> pass
\nsleep 1
\ndone
\n\/scripts\/ftpupdate
\n<\/code><\/p>\n

What actually this script is doing?<\/p>\n

01. Makes a sorted list of \u2018\/etc\/trueuserdomains\u2019 [sort with usernames] in a file \u2018LIST.txt\u2019
\n02. A File Descriptor opened for \u2018LIST.txt\u2019
\n03. Opened a for loop to itarate each users in \u2018\/etc\/trueuserdomains\u2019
\n04. Read the first line in the FD and remove the same on each iterartion
\n05. Store a date format in a variable for generating password
\n06. Store a part of user name, say from third character of the name to last character, in varaible for complicating the generated password
\n07. Executing the cPanel password changing script with appropriate parameters
\n08. Outing the information [Domain Name, User Name and New Password] to a file named \u201cpass\u201d on each iteration
\n09. Making a delay of 1 second on each iteration
\n10. Ending the for loop
\n11. Running cPanel password synchronization script.<\/p>\n

another method:<\/p>\n


\n#! \/bin\/bash
\nfor i in `awk -F: '{print $2}' \/etc\/trueuserdomains`
\ndo
\ntmp=`mkpasswd -l 10`
\n\/scripts\/chpass $i $tmp
\necho \"$i $tmp\" >> newpasswds
\ndone
\n<\/code><\/p>\n

Save this in a .sh or some file and give exec perm chmod +x filename and then run it. You will get all new users and passwords from newpasswds file in running location.<\/p>\n","protected":false},"excerpt":{"rendered":"
