A method of dynamically adapting a secure graphical password sequence provides a secure means to access a restricted account through a dynamic password defined by element selection requirements. A selection grid is dynamically generated with graphical elements, and a password sequence is inputted by selecting certain grid cells containing graphical elements. Various preferences provide full customizability for the dynamic password, and security measures increase the difficulty of an undesirable user ascertaining the element selection requirements. The dynamic password can adapt over time through user input by designating one of the sequential locations of the password sequence as a sequence updating parameter.
