This article describes how you can bypass the login screen when accessing SmartForms sites. If you want to allow users to log in to a form without needing to select an authentication method, you must set up a realm in your claims configuration to use a single issuer such as the K2 Windows STS or the K2 Forms STS.
The login page is shown if there is more than one linked issuer configured for the realm (the site URL). To bypass this page and let users log in directly, make sure there is only one linked issuer for the realm.
See the K2 Five User Guide for more information on Claims configuration.
