  • Patent number: 11354400
    Abstract: Data from a SaaS application may be stored and accessed locally, enabling SaaS data to be interacted with, regardless of connectivity, while providing secure authentication when offline. When online, a user may perform an authentication procedure and provide credentials to an application server, which may provide an authentication token for access to secure data or applications. The authentication token and user credentials may be cached locally. When offline or experiencing intermittent connectivity, if user provided credentials match the cached credentials, then the client application may retrieve the cached authentication token and allow the embedded browser to resume utilizing the network application and/or data; while if the new credentials do not match the previously provided and cached credentials, access may be denied. Thus, the embedded browser may perform authentication agnostic to whether the device is online or offline at that time, requiring no changes to the browser or network application.
