Create a new user and password for your database:
myfirstdb is the name of your database and the .* grants the same privileges to all tables (you could fine tune this by replacing the * with a table name).
yourusername is the username
yourpassword is the password
After grant are the privileges, if you want to give them full access you could just use "GRANT ALL" or if you want to restrict them to only reading you could just use "GRANT SELECT" and any other number of options that meet your needs for security.
GRANT SELECT, INSERT, DELETE on myfirstdb.* to yourusername@localhost IDENTIFIED BY 'yourpassword';
