Disabling a client authentication certificate immediately stops a service user from accessing APIs or other systems that rely on it.
You may want to disable a client authentication certificate if:
The certificate is no longer needed.
You need to block API access for security or maintenance reasons.
A new certificate will replace the current one.
Caution
If your API integrations depend on this certificate, replace your client authentication certificate first. Otherwise, disabling it will cause API communication failures.
You can enable the client authentication certificate at a later stage, if you choose.
Sign in to DigiCert ONE.
