SciFinder access changes

Starting December 18, 2025, CAS will implement a new security measure that may affect how users in your organization access CAS SciFinder^® and related applications. 

The update will impact the active use of an ID from multiple devices/browsers at the same time.

How it works: 

User logs in with username and password. 

1. If the username is not signed in and active elsewhere, access proceeds as usual. 
2. If the username is already signed in and active on another device/browser: 
• A verification code is sent to the email listed for the username. 
• The user enters the code to complete the?login process or closes the window and does not complete the login process. 
• If the code is entered and the login is completed, the previous login for that same username will be signed out. 

If you have any questions or need support, please contact the CAS Customer Center.
