RESOLVED: Duo: Authentication via phone call and SMS unavailable

Update, Friday 2/14: Duo reports that this issue is resolved and all methods of communication are operational.


Today, Duo identified an issue where authentication via phone call or SMS/text messages is failing. Until the issue is resolved, community members will need to authenticate via Duo Mobile Push, passcodes from the Duo Mobile App, or security/hardware tokens.

Please remember that LITS will never ask you to initiate a Duo Push or to send us a passcode/SMS message. You should only approve Duo authentication requests that you initiated yourself. It never hurts to decline a Duo request if you’re unsure.

We will update here as more information becomes available. If you have any questions, please contact the Help Desk: 610-526-7440 or help@brynmawr.edu.
