Description

All superset installations should always set a unique secure random SECRET_KEY. Your SECRET_KEY is used to securely sign all session cookies and encrypting sensitive information on the database. Add a strong SECRET_KEY to your superset_config.py file like:

SECRET_KEY = <YOUR_OWN_RANDOM_GENERATED_SECRET_KEY>

Alternatively you can set it with SUPERSET_SECRET_KEY environment variable.
