  • Authentication via an OpenAthens session lasts for 8 hours.
  • Once you login to one subscription-based library resource via OpenAthens, you will not need to log in again to use others, unless you close your browser.
  • OpenAthens login is required for licensed content, even when inside the library, with the exception of a few resource platforms.
  • On many publisher/provider platforms, you can look for a login button, click it and use the "find your organization" box to search for Princeton Theological Seminary. After selecting Princeton Theological Seminary, follow the prompt to log in with your Princeton Seminary email and password.
