Trouble Logging In?

The most common problems logging in to CAS SciFindern are because:

You are not using the off-campus proxy.  If you get a message that you are "Not authorized from this IP address", you need to use the link: https://go.openathens.net/redirector/utoledo.edu?url=https%3A%2F%2Fscifinder-n.cas.org%2F

Wrong Username or Password.  If you cannot remember your username or password, you can retrieve it using your e-mail address and the answer to your security question at the 'Forgot Username or Password?' link on the Login screen.
