2-Factor Authentication


UC Merced Single Sign On (SSO) requires 2-factor authentication for all faculty, staff, student, and affiliate accounts. The preferred method for 2-factor authentication is using a mobile phone, either via the Duo app or SMS text messaging. Individuals who do not have a mobile phone or prefer to not use a personal device may instead register other devices and/or multiple devices to authenticate to UC Merced Single-Sing-On (SSO) services. You can also register a tablet, a basic cell phone, VoIP and landline phones, or obtain a special hardware token from the OIT Service Desk.
