Question Regarding API Usage for Gemini Integration

Hello,

We are an enterprise-level user, and our company produces thousands of devices. Based on your suggestion of using separate API keys for each device, I would like to ask:

1. How can we efficiently create and manage unique API keys for thousands of devices? Are there tools or bulk management processes available to handle this scale?

2. How can we ensure the confidentiality of each device's API key to prevent exposure or misuse? Do you have recommendations or best practices (e.g., implementation examples or security configurations) to securely store and protect the API keys on devices?

3. To streamline the process, does Google provide scripts, automated workflows, or related documentation to help implement API key distribution and secure management in large-scale deployments?

We are trying to implement this securely and efficiently, so any additional guidance or examples regarding device-level integration at this scale would be greatly appreciated.

Thank you for your assistance!
