Publishable and Secret Keys
In early Clerk SDKs, developers were required to configure three keys:
- Frontend API URL
- API key
- JWT key (depending on the SDK version)
New SDKs have replaced these with two keys:
- Publishable Key (prefixed with
pk_test_
orpk_live_
) - Secret Key (prefixed with
sk_test_
orsk_live_
)
The name and format of these keys are common among developer tools, and we adopted them to provide a more familiar developer experience.
Although legacy keys will remain operational, we have updated our documentation and code samples to use the new Publishable Key and Secret Key format.
We recommend updating at your earliest convenience.
