    Secure API keys in a .NET Blazor application by storing them in environment variables or secure configuration files, not in the codebase. Use user secrets for development and Azure Key Vault for production. Implement proper access controls and avoid exposing sensitive information in client-side Blazor. Rotate API keys regularly and use HTTPS to encrypt data in transit.
