Un sistema de gestión de contraseñas de varias partes que genera contraseñas al vuelo.
XYfer is a multi-part password management system that generates passwords on the fly based on a master password. XYfer encapsulates the information needed to generate the password in Shakers. Each Shaker contains a Shaker name, user name, a list for security responses and a password pattern field that defines the requirements of the password to be generated. The idea behind a Shaker is simple; all the parts needed to recreate the password are not contained within the Shaker. The master password is needed and that is the only password the user needs to remember. A Shaker is guaranteed to always generate a password, regardless of what the value of the master password is. Only when the intended master password is introduced to the Shaker, then and only then the expected password will be generated.
