Regular API key rotation is a security best practice. But poorly executed, it can break your integrations and cause outages.
Plan and monitor your rotations for a painless transition.
Why Rotate
- Security: a compromised key must be revoked. Preventive rotation limits exposure window.
- Compliance: some standards (PCI-DSS) require periodic credential rotation.
- Hygiene: old keys may have been shared or inadvertently exposed.
Rotation Strategy
- Dual key period: activate the new key before deactivating the old one. Cohabitation period.
- Progressive update: update systems one by one during the transition period.
- Validation: verify all systems use the new key before revocation.
Automate with MoniTao
- Dual monitoring: monitor with both keys during transition.
- 401 alert: immediately detect if a system still uses the revoked old key.
Frequently Asked Questions
What rotation frequency?
Every 90 days is good practice. More frequent for very sensitive keys.
How to know if all systems are migrated?
Monitor old key usage logs. No calls = complete migration.
Can I automate rotation?
Yes, with tools like HashiCorp Vault or AWS Secrets Manager.
What to do for a compromised key?
Immediate rotation without transition period. Instant old key revocation.
