# Document Properties: Access

The Access properties page allows you to provide a user name and password for accessing source files on web servers that request authentication information. Note that iSiloX only supports the HTTP Basic Authentication mechanism. You can usually tell that a web site uses this mechanism if when you access the site, your browser pops up a dialog asking for your user name and password. You can usually tell that a web site does not use this mechanism if when you access the site, you get a page with a form for you to enter your user name and password.

Note that this is not where you enter your user name and password for your proxy. To do this, you need to go to the Tools menu, select Options, and enter the information under the Proxy tab. See Options: Proxy for more information.
