Get the Chrome Extension
F*#$ Duo is a Chrome extension that uses Google Voice to automate two factor authentication processes.
Much like Burger King, we place the right to choose in the hands of the customer. With F*#$ Duo, you can take that right back from annoying tech departments and other people who implement annoying tech policy.
Go to Google Voice and get a free number. Make sure to remember the number!
Go to F*#$ Duo and add the Chrome Extension. After adding the extension, go to ERNIE and login. In the Duo login section, click 'Add a new device.' Add your new Google Voice number, select 'Other' in phone type, and set it as the default number. If you do not set it as default, F*#$ Duo will not work. Finally, click the new 'F!' button in the top right of your browser and enable F*#$ Duo.
Go to ERNIE and sign in like you would normally.
