How can I change the default root password in Arch Linux?

By default, Arch Linux does not have a root password set, so all root permissions operations are carried out using the sudo command. If you need to set a root password, you can follow the steps below:

1. Open the terminal and log into the system as a regular user.
2. switch user
3. Change password
4. Enter a new root password and confirm.

Now that you have successfully changed the root password for Arch Linux. Remember, it is recommended to only use the root account when necessary, and to use a regular user account for everyday tasks, obtaining root privileges through the sudo command when needed.
