Workaround
When you successfully log into a 2-Step-protected application, your browser remembers the authentication previously method used and defaults to that method for all future logins.
If you want to try a different method, click "Other options"
The next page displays a list of your registered and available authentication methods.
Once a different option is chosen (e.g. Duo Push), you will be prompted to authenticate with the newly selected option.
Once you have authenticated, click "Yes, trust browser" and the browser will automatically remember you for 30 days.
If you select "NO, do not trust this browser", you will still authenticate and continue on to the application, however, you will be prompted to re-authenticate each time you log into an application on that browser.
