Cookie Authentication on the Portal or Gateway

Cookie authentication simplifies the authentication process for end users because they will no longer be required to log in to both the portal and the gateway in succession or enter multiple OTPs for authenticating to each. This improves the user experience by minimizing the number of times that users must enter credentials. In addition, cookies enable use of a temporary password to re-enable VPN access after the user’s password expires.
You can configure cookie authentication settings independently for the portal and for individual gateways, (for example, you can impose a shorter cookie lifetime on gateways that protect sensitive resources). After the portal or gateways deploy an authentication cookie to the endpoint, the portal and gateways both rely on the same cookie to authenticate the user. When the agent presents the cookie, the portal or gateway evaluates whether the cookie is valid based on the configured cookie lifetime. If the cookie expires, GlobalProtect automatically prompts the user to authenticate with the portal or gateway. When authentication is successful, the portal or gateway issues the replacement authentication cookie to the endpoint and the validity period starts over.
Consider the following example where you configure the cookie lifetime for the portal—which does not protect sensitive information—as 15 days, but configure the cookie lifetime for gateways—which do protect sensitive information—as 24 hours. When the user first authenticates with the portal, the portal issues the authentication cookie. If after five days, the user attempted to connect to the portal, the authentication cookie would still be valid. However, if after five days the user attempted to connect to the gateway, the gateway would evaluate the cookie lifetime and determine it expired (5 days > 24 hours). The agent would then automatically prompt the user to authenticate with the gateway and, on successful authentication, receive a replacement authentication cookie. The new authentication cookie would then be valid for another 15 days on the portal and another 24 hours on the gateways.
