Employees can better protect institutional and personal data by opting in to two-factor authentication (2FA) when signing in with UW NetID on the web. As an employee, you already use 2FA to sign in to Workday and other systems. By opting in to 2FA on the web, you help ensure your UW NetID and other systems are protected too. 2FA adds a layer of security when you sign in with your UW NetID. First you enter your password, then use a 2FA device to prove it’s really you.
