We need to completely delete the existing “pi” user because it is a security issue. Everyone knows that a Raspberry Pi has a default user name of “pi” so we need to replace that.

In the terminal, type:

We need to create a new user with the same group allocation.
To create a new user, use the useradd command with a list of all the groups copied from the above list less the pi group. In my case it looks like this but yours will look slightly different:

Now create the password using:
Enter in the new password and reboot using:
Now login with the new username.
