HTTP provides a general framework for access control and authentication. The most common HTTP authentication is based on the Basic schema, but others such as Digest and Bearer are also available. WebCopy directly supports Basic schema, although Bearer can be used via custom headers.
In addition, you can use an embedded web browser to log into a site manually prior to WebCopy crawling the site. This can be useful for more complex authentication systems that are not directly supported, such as multi-factor.
