Protecting Secrets with AWS Secrets Manager
Stop hardcoding credentials in Lambda. Learn to store, rotate, and retrieve API keys and database passwords securely using AWS Secrets Manager.
Why Not Hardcode Secrets?
Embedding API keys or DB passwords in your Lambda code or environment variables is risky: anyone with read access can see them, and rotating them means a redeploy.
AWS Secrets Manager centralizes secrets, encrypts them, and supports automatic rotation.
What Secrets Manager Stores
Common secrets include:
- Database credentials
- Third-party API keys
- OAuth tokens
- Encryption keys
Each secret is encrypted at rest with AWS KMS.
