 > [!NOTE]
 > This assumes that you've set your Codecov token inside *Settings > Secrets* as `CODECOV_TOKEN`. If not, you can [get an upload token](https://docs.codecov.io/docs/frequently-asked-questions#section-where-is-the-repository-upload-token-found-) for your specific repo on [codecov.io](https://www.codecov.io). Keep in mind that secrets are *not* available to forks of repositories.
 
+### Using OIDC
+For users with [OpenID Connect(OIDC) enabled](https://docs.github.com/en/actions/deployment/security-hardening-your-deployments/about-security-hardening-with-openid-connect), the Codecov token is not necessary. You can use OIDC with the `use_oidc` argument as following.
+
+```yaml
+- uses: codecov/codecov-action@v4
+  with:
+    use_oidc: true
+```
+
+Any token supplied will be ignored, as Codecov will default to the OIDC token for verification.
