Abstract
A system maintains a web session across multiple web resources and/or devices using a two-token model. A user agent transmits an authentication request to a login endpoint. The user agent have access to a grant token, and it will receive an access token in response to the authentication request. The grant token is relatively long-lived and the first access token is relatively short-lived. The user agent will use the access token to access the first web resource and establish a web session. When the access token expires or is about to expire, the user agent will transmit a re-authentication request with the grant token to a re-authentication endpoint. The user agent will then receive a second access token from the re-authentication endpoint. The user agent will then use the second access token to access the web resource and maintain the web session.
