Not automatically. A key can still work and still be exposed, over-permissioned, or subject to a provider policy that requires replacement. Ask support what prompted the recommendation, verify the request through the provider’s official support channel, and treat credible signs of exposure as a security incident. The title does not identify the provider or the agent’s reason, so the right action depends on those details.
Why would support recommend replacing a working key?
“Valid” only means the provider may still accept the key. It does not prove that the key has remained private, that it has only the access your application needs, or that it meets the provider’s current policy. Support may be responding to suspected exposure, unusual activity, a policy change, an upcoming deprecation, or another account-specific finding. Without the provider and the agent’s rationale, none of these can be assumed.

Ask the agent what triggered the recommendation and request the relevant incident details or policy reference. Do not send the key in a reply or include it in a support ticket. If the message was unexpected, confirm it independently through the provider’s known official support route.
Decide based on the evidence
| What you know | What to do |
|---|---|
| Support has identified exposure, suspicious activity, or a policy requirement. | Follow the provider’s incident or policy procedure. If exposure is plausible, prioritize containment and replacement over keeping the old key active. |
| No specific reason or evidence has been established. | Verify the request and ask for its basis. Review the key’s restrictions and usage before deciding; do not replace it solely because it still works or because an unexplained request arrived. |
Replacement can disrupt applications that depend on the old credential, so plan how to update those systems. That operational cost does not outweigh containment when a key may be compromised.

Check the key’s permissions and activity
Review which applications and APIs can use the key, whether its restrictions match its intended use, and whether recent activity is expected. For Google Cloud keys, the provider documents application and API restrictions and monitoring in Best practices for managing API keys. Google Cloud says, “By adding restrictions, you can limit the ways an API key can be used, reducing the impact of a compromised API key.” Those controls are specific to Google Cloud; other providers have their own settings and terminology.
If exposure is plausible, replace the key safely
- Contain access: follow the issuer’s steps to disable or revoke the affected key. Do not leave a suspected exposed credential active while waiting for a routine support response.
- Create a replacement: issue a new key with only the permissions and allowed uses the application requires.
- Update dependencies: change the credential in each application or workflow that uses it, following the provider’s procedure for avoiding unnecessary downtime.
- Review activity: inspect usage for unauthorized requests and follow the provider’s incident guidance if anything looks suspicious.
Exact console paths and rotation procedures vary by provider and credential type. OWASP’s Secrets Management Cheat Sheet recommends rapid containment and revocation of exposed secrets; Google Cloud also provides provider-specific guidance for managing API keys.

Keep the replacement out of source code
Do not hardcode the new credential in application code or commit it to a repository. GitHub’s guidance, Keeping your API credentials secure, states: “Never hardcode authentication credentials like tokens, keys, or app-related secrets into your code.” For GitHub workflows, use protected encrypted secrets; for application credentials, consider an appropriate secret manager. Restrict the key’s scope and monitor its use.
