Systems and methods for enhancing security of single sign-on are described. These systems and methods can reduce the amount of sensitive information stored on a client device while still providing single sign-on access to shared resources such as virtual desktops or Terminal Servers. For example, storage of authentication information on client devices can be avoided while still allowing client devices to connect to the shared resources. Instead, such information can be stored at a broker server that brokers connections from client devices to the shared resources. The broker server can facilitate more secure single sign-on by providing a single-use ticket to a client device that authenticates with the broker server. The client device can use this single-use ticket to authenticate with a shared resource.
