How to mysqldump in a more secure way?

How can I get the following script to be more secure? I am getting a mysqldump warning.

mysqldump: [Warning] Using a password on the command line interface can be insecure.

mysqldump:
# Dump MySQL in staging area
echo "------------------------------------------------"
echo "Dumping MySQL..."
mysqldump -h "$host" -u "$username" -p"$password" "$dbName" > ~/tmp/"$projectName"/database.sql
echo "Done!"

Thanks!

Tried out this solution and am getting the following error.

mysqldump: Got error: 2002: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) when trying to connect using

Bash:
mysqldump --defaults-extra-file=~/.sqlpwd [database] > ~/tmp/"$projectName"/database.sql

with the .sqlpwd being this

Bash:
[database]
host=domain.abc.com
username=user
password=pass
dbName=database_name

Any ideas?
