When a user is attempting to access a server application, a challenge is received, in a browser, for a one or more login credentials to access a server application (e.g., a web page). For example, a user is requested to provide a user name and password to login to the server application. In response to the user providing the credentials via the browser, the login credentials are sent. If the credentials are validated, an access token is received by the browser from the server application. In response to receiving the access token for the server application, the browser sends the access token and an address for the server application, via a local loopback address, to a local application. This allows the local application to send local information, such as local files, to the server application using the token.
