Abstract
Facilities are provided herein for authenticating a user to use a processing device. A user predefines authenticators of one or more types and associates these with graphical images. Upon on attempt to activate the processing device, a graphical image, of the graphical images, is selected for presentation to the user. The selected graphical image is presented to the user, who then provides input to authenticate with the device. A determination is made as to whether the user is authenticated to use the device. The determination is made based on input received from the user and based further on the authenticator associated with the selected graphical image. Varying the selection of image(s), each associated with a predefined authenticator and authentication type, enables variability in the authenticator that is suitable for unlocking a device at a given time, providing greater security to the authentication process.
