  passwd yourusername

Grant Sudo Access to the New User

CAUTION

Modifying the sudoers file incorrectly can lock you out of administrative privileges. Be cautious!

1. Open the sudoers file:

   EDITOR=nano visudo

2. Uncomment the following line by removing the #:

   %wheel ALL=(ALL:ALL) ALL

This grants sudo access to all users in the wheel group.
