Resolved: Known Issue

Last updated on February 8, 2018 at 7:21AM

Update on February 8, 2018 at 7:21AM

This issue has been resolved via CHG0046724, which has been successfully implemented. If you continue to have issues with WebAccess and authenticating with Duo, please contact the IT Service Desk.

Original Alert

As of 6 a.m. EST on Tuesday, February 6, 2018, the Duo Authentication service is experiencing problems on Mac platforms (Mac Safari; any browser on iPhone or iPad). The "Send text ..." link (to get new passcodes via SMS) is not working correctly. As a workaround to authenticate at this time, you can choose another authentication option (call, Duo Push, etc.) or clear your browser's cache before using Duo.

Penn State IT staff members are implementing a fix tomorrow, Wednesday, February 7, 2018, during the normally scheduled maintenance window from 5 - 7 a.m. EST.

For more information, please contact IT Service Desk (
