An access token is an object that describes the security context of a process or thread and is allocated to each user logged onto a Windows NT or Windows 2000 system. These access tokens can be represented with the CAccessToken class.

It is sometimes necessary to impersonate access tokens. This class is provided as a convenience, but it does not perform the impersonation of access tokens; it only performs the automatic reversion to a nonimpersonated state. This is because token access impersonation can be performed several different ways.

For an introduction to the access control model in Windows, see Access Control in the Windows SDK.
