Hi,
I've been using an OBi200 with a Google Voice account for years. and it has generally worked well. I recently switched 2FA on for the Google account, enabling a hardware token (FIDO / U2F). This works fine for web access, but it seems to have broken the OBi GV functionality. I can't be sure that that's what's going on here, but nothing I tried got GV working again (including multiple reboots and deleting the entire SP1 configuration and recreating it by going through the Google app authorization flow again), until I disabled 2FA, at which point GV promptly came back to life (after a reboot).
From browsing this forum, I had the impression that 2FA should not prevent the OBi from working with GV. Can anyone help? Thanks.
