Once we've created a user, we can test the new account by logging out of MySQL by typing exit and then logging back in as the new user:

mysql -u bobrocker -p
Enter Password: 7PzoBROs7D1zwW6Qna3mvWNDMIwktCBe

When asked for the new password, just copy and paste it into your terminal and hit Enter. Don't try to type it out by hand.
