First things to do with a Raspberry Pi 4 (Raspbian Lite)

Initial Changes

• Change User Password
• Change Hostname
• Enable SSH
• Change Time-Zone
  sudo timedatectl
• Memory Spit
  sudo raspi-config

Change username

1. Choose a secure password for the root user.
   sudo passwd root

2. Logout. And then log back in as the user 'root' using the password you just created. ...

3. Rename User
   usermod -l newname pi

4. Assign Home Folder
   usermod -m -d /home/newname newname

5. Now logout and login back in as newname

6. If you wish you can disable the root user account again but first double check newname still has
   'sudo' privileges. Check the following update command works:
   groups newname
sudo apt-get update

7. If it works then you can disable the root account by locking the password (if you want to)
   sudo passwd -l root
