Nearly 3,000 Google API keys were accidentally exposed via Gemini in early 2026, highlighting the growing risk of credential leakage in AI-integrated systems. Ten practical security measures are covered: avoid hardcoding keys in source code, use dedicated secrets managers like AWS Secrets Manager, automate key rotation every 30–90 days, limit key scope to least privilege, keep keys server-side and never in AI-accessible contexts, enforce strict input/output boundaries to counter prompt injection, prevent AI from constructing raw API requests, allowlist approved IP addresses, monitor for unusual API usage patterns, and use trusted execution environments (TEEs) for sensitive workloads.
