It demonstrates how to build a Python Flask web app with registration & login via oath, routing, database integration and more.

1. Clone repository
2. Pip install requirements.txt
3. Update .env_sample with your info and rename to .env
   • The secret_key is used by WTForms to prevent CSRF attacks and also for serializing our password reset tokens
   • the token_hex function from the secrets module is an easy way to generate your secret key
   • Use your own email address and pw for the email server (used for pw reset emails). NOTE: You may need to enable "less secure apps" access to your email temporarily if you receive a warning.
4. Run the app: $ python run.py
