You can use this if you are a current member of the university, or if you graduated on or after Summer 2013 (Raven for Life).

If you trust this application, choose a login option to authenticate with your SRCF or Raven account.
Regardless of which you choose, the application will receive your CRSid (and with Raven login, whether you are a current student and/or staff member). No other personal information will be included.
