1. A method for authenticating a user, the method comprising: receiving, by a first computer, a request for a user log in from a user computing device; authenticating, by the first computer, an identity of the user and granting the user access to applications hosted on the first computer, wherein one of the those applications is an access portal to a second computer; searching, by the first computer, a storage unit for a unique identification that is associated with the user, and determining, by the first computer, that the unique identification has not been found in the storage unit; in response to not finding the unique identification in the storage unit, generating, by the first computer, the unique identification to be associated with a user, based on a unique arbitrary value to generate a universally unique identifier; storing, by the first computer, the generated unique identification in the storage unit; receiving, by a second computer, a request for a user log in from the access portal hosted on the first computer; determining, by the second computer, if the unique identification accompanies the received user log in request, wherein the unique identification is used to authenticate the identity of the user; determining, by the second computer, if the unique identification has been previously received by searching a database to see if the unique identification was already stored in the database; in response to the unique identification not being previously received, determining, by the second computer, whether the unique arbitrary value grants access to an application on the second computer, and storing, by the second computer, the unique identification to the database; granting, by the second computer, access to the user to the application hosted on the second computer based on the determination.
