Hi @innoxgraphics,
Thanks for reaching out.
With the free plan, we do provide authentication via secure Basic Auth and JWT authentication along with the options to choose which APIs you want to make public or requires authentication. You can configure any of these methods to authenticate your WordPress REST APIs.
And in case if you are looking for advanced authentication methods like OAuth 2.0, API key authentication and other security features. Then, yes there are available with our premium plans.
Also, it will be great if you can raise an internal ticket by dropping an email to [email protected] and tell us more about your use case and the feature requirements. So, we can assign a technical engineer to help you further.
Thanks,
Team miniOrange
