How to Change Passwords in Linux

In Linux, you can change your own password or another user's password using the passwd command.

To change your own password:

passwd

• You’ll be asked to enter your current password.
• Then you’ll be prompted to enter a new password twice.

To change another user's password as an administrator:

sudo passwd username

• You must have sudo privileges.
• Useful for system administrators managing multiple users.

About passwd username without sudo

passwd username

• This only works if you are logged in as the root user.
• Regular users cannot change other users' passwords with this.
