What is 2FA?
2FA adds a layer of security when you sign in with your UW NetID. With 2FA, first you enter your password, then use a 2FA device to prove it’s really you.
When do I sign in with 2FA?
You must sign in with 2FA to access systems such as Workday or Hyak that require 2FA, or when you or an organization you belong to has opted in to 2FA on the web.
Why do I need 2FA?
2FA prevents others from signing in as you, even if they know your password. It protects you and the UW from the risks of phishing scams and other forms of passwords theft.

Sign in with 2FA
Once you set up a device, you’ll be ready to sign in with 2FA.
Sign-in options depend on your choice of device (above). They include:
- “Send Me a Push” – Duo sends a notification to Duo Mobile on your smartphone or tablet. You then tap “Approve” to sign in. An internet connection (Wi-Fi or cellular data) is required to receive push notifications.
- “Enter a Passcode” – Open Duo Mobile on your smartphone or tablet to generate a passcode, with or without an internet connection. Or, if you have a hardware token, use the passcode from it.
- “Call Me” – Duo calls your smartphone, mobile phone, or landline. Answer the call and follow the instructions to approve. This option only works with phone numbers in the US and parts of Canada.
