''Authorization'' is the process of determining which resources may be accessed by a particular user. It occurs after [[authentication|WebServer Authentication]] has determined the identity of the user. TiddlyWiki's WebServer implements a simple authorization scheme which permits independent control of who has administrator access to the server, and read and write access to a wiki.
The WebServer parameters [[admin|WebServer Parameter: admin]], [[readers|WebServer Parameter: readers]] and [[writers|WebServer Parameter: writers]] each contain a comma separated list of //principals// (which is to say, either usernames or certain special tokens) which should have read or write access respectively.
<<.tip"""The ''(anon)'' token is not valid for the [[admin|WebServer Parameter: admin]] parameter.""">>
At this time, no server functions are restricted to ''admin'' authorized users in the unmodified [[Tiddlywiki server|WebServer]]. Third party plugins can leverage this to restrict routes or commands to a subset of authorized users.
