US Patent 9483627 Abstracting credentials for mobile client authentication

A computing system receives an authentication request from a user device for access to a web application hosted in a cloud and determines that the authentication request is a candidate for modification based on initial user credentials in the authentication request. The computing system modifies the authentication request to include replacement user credentials that correspond to the initial user credentials and transmits the modified authentication request to the web application in the cloud. The web application determines whether the modified authentication request is valid based on the replacement user credentials.
