How to protect metadata page(s) with authentication/credentials?

ServiceStack Metadata

Is there a built-in way to protect (w/ user credentials) metadata page and also all operation documentation pages?

You can’t limit the Metadata page but you disable the Metadata page in Release builds with:

#if !DEBUG
Plugins.RemoveAll(x => x is MetadataFeature);
#endif

You can also Restrict and Hide Individual Services with the Restrict attribute.
