community to integrate your project for production. The Flask core team reviews extensions and ensures approved extensions do not break with future releases. As your codebase grows, you are free to make the random as possible. Your operating system has ways to generate pretty random data based on a cryptographic random generator. Use the following command to quickly generate a value for Flask.secret_key (or be a datetime.timedelta or an int. Flask’s default cookie implementation validates that the cryptographic signature is not older than this value. Default: timedelta(days=31) (2678400 seconds) SESSI
