You can use the chpasswd command to change passwords for multiple users in Ubuntu. Here’s how you can do it:
userlist.txt) with the list of username:password pairs for the users whose passwords you want to change. Each line in the file should have the username and the new password separated by a colon, like this:user1:newpassword1
user2:newpassword2
user3:newpassword3
sudo chpasswd < userlist.txt
This will update the passwords for the specified users in bulk. Make sure to replace userlist.txt with the actual file name if it’s different.
