# Rename default user 'pi' to 'alex'
#
# In order to change the username 'pi' we will have to log in a the root user since it's not possible to rename an account while your logged into it. To log in as root user first we have to enable it, to do so type the following command whilst logged in as the default pi user:
sudo passwd root

# Login, and edit this file: 
sudo nano /etc/ssh/sshd_config

# Find this line: PermitRootLogin without-password
# PermitRootLogin yes

# reboot
sudo reboot

# Choose a secure password for the root user. You can disable the root account later if you wish.
# Now logout of the user pi using the command:
logout

# And then logout back in as the user 'root' using the password you just created. Now we can rename the the default pi user name. The following method renames the user 'pi' to 'newname', replace this with whatever you want. Type the command:
usermod -l alex pi

# Now the user name has been changed the user's home directory name should also be changed to reflect the new login name:
usermod -m -d /home/alex alex

# If it works then you can disable the root account by locking the password:
sudo passwd -l root
