A convenient and secure system and method for access to any number of password-protected computer applications, web sites and forms without adding to the user cognitive load and without circumventing the inherent security of such password-protection schemes. An existing password field on a device display is overlaid with password wallet pop-up field which allows a wallet "master" key to unlock the wallet. An application-specific and/or user-specific password is automatically retrieved from the wallet and entered into the password field with no other user action required.
