Abstract
An example method is provided for an electronic device, which may have a display and an input interface, to perform password authentication. The example method may include generating at least one sequence of input elements for entry during the authentication of the user's password to disguise entry of the user's password via the input interface by increasing the user's contact with the input interface and prompting, on the display, for an entry of the user's password and the at least one sequence of input elements via the input interface. The example method may further include receiving, via the input interface, entry of the user's password and the at least one sequence of input elements and determining whether the authentication is successful by checking whether the received entry is correct.
