Abstract: Disclosed are systems and methods for improving interactions with and between computers in an authentication system supported by or configured with personal computing devices, servers and/or platforms. The systems interact to identify and retrieve data across platforms, which data can be used to improve the quality of data used in processing interactions between or among processors in such systems. The disclosed systems and methods enable users to access web-based resources on a first device by authenticating themselves on a second device. A user can provide identifying information to a web-based resource on a first device, and as a result, the user receives a message at his/her already registered second device. The user then authenticates himself/herself on the second device by reusing the means of authentication that exist on the user's second device, which results in the user being granted entry to the web-based resource on the first device.
