The MFA Phone Call (“Call Me”) Option Was Eliminated
On Thursday, October 6, 2022, phone calls were eliminated for all NYU community members (the “Call Me” option in the Duo prompt and “phone1” in NYU VPN) as a method of MFA authentication. Instead, everyone should use Duo Push – the easiest, most secure way to authenticate. To regain access, call the IT Service Desk or your school/unit help desk, then switch to Duo Push.
Use Duo Push
To ensure uninterrupted access to your NYU account, and to protect your data and the availability of NYU’s network, switch to using Duo Mobile with the Duo Mobile app and in NYU VPN.
