Google 2FA Barcode

We recently had to install Piwik onto a new server and I had Google 2FA installed on the previous install. I just happened to also purchase a new phone today.
When I enable the Google 2FA plugin it immediately logs you out of Piwik without giving the option to display the barcode.
I was wondering how I could get a new barcode so that I can continue to use 2FA on Piwik?

Thank you
