To change the password for the root user or any other user on an OpenBSD system, you can use the passwd command. This command is used to change the password for the user account associated with the current terminal session.
To change the password for the root user, open a terminal and log in as root. Then, enter the following command:
refer tuttual:ori.compasswd
The passwd command will prompt you to enter the current password for the root user, followed by the new password that you want to set. After you have entered the new password, passwd will ask you to confirm the new password by retyping it.
To change the password for a different user, use the passwd command followed by the username of the user whose password you want to change. For example, to change the password for the user john, you would enter the following command:
passwd john
The passwd command will then prompt you to enter the new password for the user john.
Keep in mind that the passwd command is only available to users with administrative privileges, such as the root user or users with the wheel group. If you are a regular user and you want to change your own password, you can use the passwd command without any arguments.
It's important to choose strong and secure passwords to protect your system and your data. You should avoid using simple or easily guessable passwords, and consider using a password manager to help you generate and store strong, unique passwords for all of your accounts.
