Two things about your question: You cannot deploy Django app on github pages because they serve only static files. Check e.g. Heroku, it's quite easy to deploy Django there. The most common practice to hide passwords and secret keys is to use environmental variables. Generally, you have to set a variable in bash e.g. export EMAIL_HOST_PASSWORD=my-own-password and then you can use os python module to retrieve it: import os EMAIL_HOST_PASSWORD = os.environ.get("EMAIL_HOST_PASSWORD") Useful video tutorials: Python Django Tutorial: Deploying Your Application (Option #2) - Deploy using Heroku [LINK] Python Quick Tip: Hiding Passwords and Secret Keys in Environment Variables (Mac & Linux) [this video]

Yes, you have to do that manually. So, within your terminal do this: % cd % nano .bash_profile It will open a file 'bash_profile' in editor in your terminal. And in there you can set environmental variables like: export DATABASE_URL="YOUR DATABASE URL" Check this video out for more info: [this video]

You will want to use os.environ example: app.config['MAIL_USERNAME'] = os.environ.get('EMAIL_USER', 'my@email.com') app.config['MAIL_PASSWORD'] = os.environ.get('EMAIL_PASS', 'mypassword') or set environment variables windows: [LINK] linux: [this video]
