Is the sensitive information present in variables automatically modified by Azure Functions?

edit

No, sensitive information present in variables is not automatically modified by Azure Functions. It is the responsibility of the developer to properly manage and secure sensitive information, such as passwords, connection strings, and API keys, within their code and deployments. Azure Functions does provide some features, such as Key Vault integration and environment variables, that can help manage sensitive information securely. Developers should also follow best practices for securing their code and deployments, such as encrypting sensitive information at rest and in transit, and limiting access to only authorized individuals.
