Techniques for increasing mobile device security

Methods, apparatus and articles of manufacture for increasing mobile device security are provided herein. A method includes establishing a pre-determined set of cryptographic information, wherein said pre-determined set of cryptographic information comprises one or more user-selected non-alphanumeric input elements applied to one or more visual components; generating a prompt via a computing device interface in connection with an authentication request to access a protected resource associated with the computing device; processing input cryptographic information entered via the computing device interface in response to the prompt against the pre-determined set of cryptographic information; and resolving the authentication request based on said processing.
