Keyboard-interactive is a generic authentication method that can be used to implement different types of authentication mechanisms. Any currently supported authentication method that requires only the user's input can be performed with keyboard-interactive.

Currently, the following methods are supported:

With the current version of SSH Tectia Server on Windows, password, RADIUS, and RSA SecurID authentication can be performed over keyboard-interactive. In the future, it may be possible to use keyboard-interactive also with other authentication methods.

Methods that require passing some binary information, such as public-key authentication, cannot be used as submethods of keyboard-interactive. But public-key authentication, for example, can be used as an additional method alongside keyboard-interactive authentication.

	Note
	PAM has support for binary messages and client-side agents, and those cannot be supported with keyboard-interactive. However, currently there are no implementations that take advantage of the binary messages in PAM, and the specification may not be cast in stone yet.
