Here are a couple of short videos which explain how to use the Duo 2FA (2 Factor Authentication) Security Solution
How does Duo Push work? (Video)
How does Call Me work? (Video)
How does entering a passcode work? (Video)
The 2fa process for using https://iupat.okta.com is the same as logging into your computer. The only difference is the computer login automatically ‘pushes’ and the portal you must make a selection.
