Usage

Run app

Use the link to the production server directly.

Clone/Modify app

Modify application.py to replace the secret key (i.e. os.environ.get('SECRET')) with a secret key of your choice and the database link (i.e. os.environ.get('DATABASE_URL')) with the link to your own database.

The two lines to be edited in application.py are shown below:

app.secret_key=os.environ.get('SECRET')
app.config['SQLALCHEMY_DATABASE_URI']=os.environ.get('DATABASE_URL')

Edit create.py to once again replace os.environ.get('DATABASE_URL') with the link to your database.
Run create.py from the terminal to create the table to hold user credentials.
