Perisit pasword when using make

Hi all

I thought I'd start with a easy question 😉

When packaging and deploying an app using a make file I define a roku_dev_target variable:
export ROKU_DEV_TARGET=192.168.1.104

I'm then prompted to enter a password:
Enter host password for user 'rokudev'

How can I persist the password either for that session or permanently?

Thanks
